If you scroll down to the October 2018 entry to this Blog you can read about the motivation for what I then called the Ten-Year Renewal Project for my 1960 Austin-Healey BT7. True to my history with this car, everything takes longer than expected! While the care and maintenance of a classic car never ends, now in October 2020 I am going to proclaim that the Renewal Project has come to its conclusion.

The good news is that I have accomplished quite a lot and I am pleased to say that the Bloody Beast is running better than it has ever run while in my ownership, and that covers forty-nine years!

This website has a separate entry for all of the major renewal efforts, so one does not have to read through everything in order to obtain more information about a particular project. However, in no particular order, the following is a summary of all that has been accomplished in the past two years:

  • Greased all suspension, steering and handbrake grease zerks.
  • Installed a fresh smear of white lithium grease on door locks, bonnet catch and boot lock.
  • Checked the ground strap in the boot for tightness.
  • Checked tightness of engine mount and shock damper bolts.
  • Checked rubber boots on on suspension ball joints.
  • Checked king pin wear.
  • Replaced fluids in gearbox, engine, hydraulic system, cooling system, rear differential. Replaced the Penrite oil in the steering box and idler with John Deere Corn Head grease to help prevent leaks.
  • Checked all dash lights for functionality.
  • Checked tightness of prop shaft bolts/nuts at both ends of the shaft.
  • Replaced the oil sump gasket with a neoprene gasket from Tom’s Imports and ceramic coated the aluminum sump.
  • Removed the PCV system components and installed an oil catch can system.
  • Replaced my intake manifold, which had two broken mounting ears due to improper installation, with another good, but used unit, sourced from Michael Salter. Jet-Hot coated the manifold before installation.
  • Cleaned and repainted the carburetor heat shield and refreshed the insulation.
  • Replaced the chromed “Austin-Healey” front shroud badge with a new component as the paint had chipped away on mine.
  • Replaced a leaking RH front Armstrong damper with a newly rebuilt unit from World Wide Auto Imports.
  • Replaced ill-fitting rear rally bumper irons with proper irons sourced from AH Spares. The first set had the bumperettes sitting too far from the rear shroud.
  • Had the HD8 SU carburetors rebuilt with delrin bushings installed by Thomas Bryant. Replaced both fuel bowl floats with nitrophyl floats. Added fuel bowl “Kouzies” from Joe Curto to insulate fuel bowls from exhaust heat and prevent vapor lock.
  • Sealed a persistent oil leak at the rear differential drain plug.
  • Adjusted valve clearances to spec. and sealed the cylinder head stud holes to prevent oil leaks.
  • Replaced the plastic (nylon?) breather fitting on the rear axle with a brass unit sold by Land Rover.
  • Replaced the clutch and brake master cylinders. Inspected the clutch slave cylinder and left it in place. Replace fluid and bled the system.
  • Installed a remote clutch slave cylinder bleeder hose from Ol Phartz Parts.
  • Replaced the original fuse panel with a seven fuse/fourteen terminal unit sourced from Charlie Hart.
  • Fabricated and installed a rear main drip tray below the engine backplate/gearbox to catch oil leaks.
  • Replaced the front cylinder block cover gasket to eliminate an oil leak.
  • Replaced the alternator with a “new” rebuilt unit.
  • Replace the Halogen sealed beam headlights with aftermarket Lucas PL 700 headlights.
  • Replaced the original fuel hose delivery system from the hard fuel line to the carbs with a new design and fittings.
  • Added carburetor ram pipes and ITG air filtration socks.
  • Added an electric pusher fan in front of the radiator.
  • Modified the design of the throttle cable routing to the carburetors from the accelerator pedal.
  • New vinyl for the RH door shut face finisher panel side. Will replace the LH side at a later date.
  • Installed new ignition wires, rotor, and distributor cap and checked the ignition timing.
  • Added a bell housing drain hole for oil leaks from the rear main bearing.
  • Replaced the water pump, mounting studs and gasket, fan belt, and upper and lower radiator hoses. Replaced the stainless steel flex fan with an asymmetric yellow plastic (nylon) fan sourced from AH Spares to reduce noise.
  • Replaced the 195 degree thermostat (for Virginia) with a 160 degree sleeved thermostat (for Florida) sourced from British Car Specialists.
  • Washed, clayed, compounded, polished and waxed the car.

A few things yet to do:

  • Replace rubber in wiper arms.
  • Replace bristle flex draught excluders (door seal) – will complete when hardtop is off the car.

October 2018

It has been approximately ten years since I wrapped up (if you ever really complete a restoration of a Healey) the restoration of the Bloody Beast. He has weathered the ten years quite well – better than me, that is for sure! I have taken good care of the Beast and completed periodic maintenance as one should. There have been a few things along the way that have required attention, such as the failure of the brake master cylinder that led to the replacement of both masters and the clutch slave cylinder while I was at it. However, for the most part, it has simply been fluid changes, tire replacements and etc.

I am sad to report that I have not driven the Healey as much as I should have during the time since I finished the restoration. About a month after I completed the restoration work I drove the Bloody Beast 8,000 miles in a cross-country trip from Rehoboth Beach, Delaware to California, up the coast to Victoria, BC and then back to Harrisonburg, VA. Between helping my son with his Bugeye, restoring a 1964 Jaguar MK2, and maintaining the 1987 Alfa, a 1969 MB 280SL and the Porsche in addition to the daily drivers there just wasn’t much time to drive! I am ashamed to say that I only put an additional 2,878 miles on the Healey in the ensuing nine-plus years. Driving, however, is the whole point of having a sports car and that is certainly true for an Austin Healey roadster. My son has now taken the Bugeye to his home. I have sold the Jaguar and the Mercedes. I now intend to spend more time driving the Bloody Beast!

After almost ten years I thought it might be healthy to go over the car carefully and examine the condition of components, check tolerances, and replace items that typically wear – even though they might be in operable condition at the moment. I will be making myself a list of items, that will probably not be in any particular order, and I will undertake some of the work as the list is added too over time. I will gradually need to accumulate parts for the work to be done.

For those who read this post, I hope you will contribute through your comments and make suggestions about anything, but particularly about items that should be added to my ten year renewal list. To be clear, an item on the list, an oil change for example, doesn’t mean that it is only to be done every ten years. I will make entries on this post chronologically as items are accomplished. I will keep a ten year renewal checklist as a separate post and add to it as I think about items to address. I will organize this list based on the categories of the Workshop Manual.

So, lets start this project! The most recent actions are listed first: Ten Year Renewal Blog

Bugeye Aluminum Cylinder Head

Posted on by
Reply

When we purchased the rebuilt 1275 engine from Rivergate Restorations about twenty years ago, we opted to go with an aluminum cylinder head. Described by Bill Perry (Rivergate owner) in this way: Improved flow and performance, Stellite valve seats, 19 pounds lighter than stock, ready for no-lead fuel, bronze valve guides – a beautiful, functional addition to Sprite/Midget – $725 price only applies to a cylinder head purchased with a rebuilt motor. 

We believe that the cylinder head is the one sold by Moss Motors. Part number 451-875. This is how Moss describes the head:

“These light-weight (9 lbs.) high strength aluminum alloy cylinder heads run cooler, allow higher compression ratios, and have a greater than 35% increase in flow rate over stock heads. Heads come with silicon-bronze valve guides and hardened valve seats. These require 1275 valves, springs, and retainers, 12mm spark plugs (our 451-890 NGK plugs are recommended), all of which must be purchased separately. These heads do not have air injection ports, and therefore should not be used for street use on cars originally fitted with air pumps.”

 

Compatible with: Exhaust Valve 423-335, Intake Valve 423-190, Upper Valve Spring Collars 460-556, Valve Spring Cotters 460-535, Double Valve Spring Set 423-470

Fitting the head to smaller bore engines will require machining of the block to ensure adequate valve to block clearance.

 

Requires coarse thread manifold studs 328-765 x 6

 

Note: The rocker oil feed design requires that if a Payen composite head gasket with rubber oil seal is used, the gasket must be reversed. “FRONT” should be to the back of the engine so that the original type copper oil passage seal is over the oil feed passage.

Rear Axle Hub/Brake Problems Again!

Posted on by

We don’t seem to be able to escape our problems with the fitment of the rear axle hubs and brake drums. A thorough accounting of the issues we faced were first documented in several videos included in an earlier post:https://valvechatter.com/?p=13569

We thought we had conquered the problems we had encountered with the hub rubbing the axle flange and with the brake drum rubbing against the brake backplate, but upon installing the road wheels and tires we discovered that all had not been corrected! 

The wheel on the left side of the car turned freely but on the right side we found that despite the hub nuts being tightened and torqued to 38 ft. lbs. as directed in the maintenance manual, the wheel and tire wobbled back and forth. It is a little hard to tell but it can be seen in the beginning of the Bugeye Restoration Video Episode Ninety-two. We then tried a pair of brand new Moss Classic Gold brake drums that we had on hand.

These allowed us to eliminate the wobble of the wheel on the axle, but the drums rubbed against the backplates just ever so slightly. All of this trial and error is shown in the Episode Ninety-two video.

We will now machine the edges of the drums and see if we can end up with a fully operational axle assembly. Stay tuned….

 

 

 

 

 

Flywheel and Clutch

Posted on by

In 2022 when we pulled the engine from the car to begin the restoration, the clutch was working just fine. However, with the engine out of the car and the gearbox already separated from the engine, It seemed the perfect time to go ahead and replace the clutch disc and pressure plate (cover) with new components. We have learned on multiple occasions that just because a part is new doesn’t mean it is better, but the clutch is definitely a wear item so we decided to buy a new disc from Rivergate and a new Borg & Beck pressure plate from A.H. Spares. We had already observed that the ring gear was pretty chewed up so we ordered a new one from A.H. Spares as well.

Upon removing the clutch and flywheel from the engine we noticed that we did have wear on the flywheel surface so we decided to go ahead and have it resurfaced. That was work was done by Southwest Hydraulic, 177 Jackson Rd, Venice, FL 34292 (941) 786-8530. We then took the flywheel, new ring gear and clutch assembly to VAMI – Venice Auto Marine Engine Machine Shop 331 Camion St. Venice Fl. 34285 (941) 484-2474 to have the ring gear replaced and the complete assembly dynamically balanced.

One VERY POSITIVE by-product of removing the flywheel was the discovery that not only had the crank rear seal, installed at the time we purchased the rebuilt 1275 engine from Rivergate, not leaked at all, the entire backplate was still pristine.

No leaks – Rear Crank Seal

Bugeye Restoration Video Episode Sixty-five https://vimeo.com/952645430/164949ac19 provides documentation of the removal of the clutch and flywheel as well as the installation of the new clutch.

These are the Borg & Beck installation instructions:

Gear Reduction Starter

We have gone back and forth between using the Lucas starter with the Bendix that engages from the rear of the ring gear and the modern gear reduction starter that engages from the front of the flywheel.We have currently replaced the starter with a modern gear reduction starter from APT Fast. Unlike the old Lucas starter it cranks until the motor fires. Definitely more difficult to install than the original, but hopefully easier starting will make it worth it. Fastening the lower bolt was accomplished by jacking up the right front, removing the tire and wheel and reaching through the hole in the frame wall. The cranking sound is very different than the Lucas starter, but functionality is substantially improved. We chose to continue to use the old pull starter switch on the dash, but could have hooked up the starter to a modern solenoid as well.

Alternator 

The only information we have on the alternator is that it is a rebuilt unit designed to replace the Lucas alternator that we had in the car previously. It’s rated output is 65 amps.

Alternator Invoice

Rather than having two bolts for the left and right ears of the alternator, a single long bolt and a stainless bushing have been added to enhance the stability of the mounting.

Exhaust

Posted on by

Nothing in our exhaust system is as original! From the header to the oxygen sensor in the exhaust pipe to the dual tip muffler, everything is a modification. We have had the header fitted since the early 2000s. We don’t have a record but we are pretty sure that it was sourced from Mini-Mania and produced by Maniflow in the U.K. The header is a long branch, 1 5/8.” Before we initially installed it we had it Swain-Coated for thermal insulation. While beautiful then, it looks a little tired now so we will send it off to Jet-Hot Coatings to have them refinish it so that it will match our intake manifold.

Header

The Jet-Hot coating now matches the intake manifold.

We purchased new exhaust pipes and a twin-tipped muffler from Maniflow to fit the header. The pipe comes in two sections. We will be installing a bung in the front pipe for an oxygen sensor to feed our AFR gauge. We also purchased Maniflow’s installation kit which has the hangers and clamps needed to do the job.

Modifying the Rear Leaf Springs

Posted on by

The rear suspension in the Bugeye is comprised of the quarter elliptical leaf springs, the shock absorbers, the radius arms and their mounting boxes, the rebound straps, the rubber bump stops, and of course, the axle. Video Episode Thirteen shows the removal of the original fifteen leaf springs: https://vimeo.com/769992972/c923375ecc

We chose to replace the original springs. The only springs readily available at this time are the 10 leaf “Rally” springs. We ordered a pair from BugeyeGuy.com along with five degree shims that will lower the car to give it a proper ride height. We disassembled these springs, removed the poor paint, cleaned them and repainted with POR-15 and installed teflon tape between each leaf to reduce friction and squeaking. That process is shown in Video Episode Fourteen: https://vimeo.com/754389824/9ab8550b67

Most of what we have read on the various forums is that the rally spec springs are a bit stiff and don’t give the ride that the original springs provided. Tom Colby of Speedwell Engineering has suggested the removal of three of the leaves to offer an improved ride and we decided to try his suggestion. We can always back up and reinsert the leaves we take out.

Tom Colby’s Spring Modification

Bugeye Restoration Video Episode Sixty-four shows the deconstruction of the springs.https://vimeo.com/989814778/55abef9a4c

It wasn’t quite as easy as just pulling out a few spring leaves. Because the remaining collection of seven springs isn’t as high as the ten leaves, the bolts and springs clasps need to be modified as well. The two 3/8″ hex head bolts (per spring) that are 3 1/4″ long were replaced with two bolts that are 2 1/2″ long. The 5/16″ compressing pins that are 2 1/2″ long were replaced with 5/16″ socket head screws. Socket head screws were used because the compressing pins have round heads that also serve to locate the spring in the chassis spring plate. Rather than rounding the edges off of a hex head bolt the socket head should work just fine.   

Two of the spring clips or brackets are of sufficient size to permit drilling an additional hole in the arms of the bracket to fit the new spring height. There isn’t room on the other two so we will try them as they are or modify at a later date.

The true test will be the ride and that is still months away!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Doors

Posted on by

Prior to installing the doors on the car, we decided to assemble the door trim. Hopefully this is the best route to take. our first step was to install the rubber door liner that we purchased from Bugeyeguys. This liner is heavy and in addition to providing a solid feel when the door is opened and closed, it should afford a certain degree of sound insulation as well. The liner was glued to the door using contact cement. The photo below shows the finished product:

Rubber door liner installed

That is where the factory stopped. However, we have decided to glue carpet to the rubber liner to give a more finished and coordinated appearance.

Glueing the carpet to the rubber door liner

Carpet installed

We then installed the upholstered door pockets. These also came from Bugeyeguys and they are an upgrade over the originals. These pockets simply slide over the door lip (as can be seen in the photo above) and push down into place. Screws are not required to secure the pockets.

Upholstered Door Pocket

Next came the installation of the polished aluminum cockpit molding. Rubber washers sourced from Bugeyeguys are installed under the thumb screws for the side curtain brackets. They minimize any scuffing that might result from taking the side curtains on and off the car.

Polished aluminum cockpit molding

It was then time to install the door latch mechanism to the door. Four pan head #10-32 x 1/2″ stainless machine screws with internal tooth washers are used to mount the latch to the door.

Door Latch Installation

The final step in the completion of the doors is the installation of the upholstered check straps. These fit through a slot in the door and are then secured to the inside of the “A” pillar of the car. The end of the strap has two metal finishing plates.

Door check strap

With the doors assembly complete it was time to install the door hinges to the car’s “A” pillar. There are two hinges per door. The hinges had been stamped with markings to signify whether the hinge was top or bottom and left door or right door. Each hinge uses three pan head 1/4″-28 x 1/2″ screws and internal tooth lock washers to mount to the car.

Unfortunately, after we mounted the four hinges we decided that there was just too much play in each hinge so we pulled them all from the car and sent them to a hinge repair specialist to install new bushings, washers, and pins so they will be as good as new.

Seating

Posted on by

The Bugeye seats were the subject of an earlier post in the restoration section: https://valvechatter.com/?p=14315  This post explains our decision process on the type of seat cover we would use and also reviews the refurbishment of the seat frames and backs.

Geoff Chrysler, owner of Rightway Heritage Trim did a beautiful job with the seat upholstery. We could not have been happier with the leather color or his craftsmanship.

MK2 Seat with inserts and horizontal stitch

The seat tracks were originally screwed to the lower seat frame with 1/4″-28 x 5/8″ flat-head screws, but before long in the production cycle the screws and nuts were replaced with rivets. Several of the rivets in the Bugeye seat tracks were loose and resulted in sloppy seat travel. We decided to drill out the rivets and return to the use of screws and nuts to hold the pieces together. We also sent the seat tracks and rails to Jartex in Forth Worth, TX to have the pieces cleaned and zinc plated. They did a very nice job. We are now ready to assemble the components.

As produced at the time, only the driver’s seat had an adjustable slider track. The passenger seat was bolted in place with four brackets to the floor. However, we also have the adjuster for the passenger seat and will be installing it. It is hard to imagine ever adjusting the seats given how little room there is in the Sprite. They will probably be pushed all the way to the rear and then never moved!

We installed three-point retractable shoulder harnesses and seat belts sourced from Bugeyeguys.com. The belts and their installation were covered in an earlier post which includes a video showing the modifications to the chassis to accommodate the fixing points.https://valvechatter.com/?p=14383

This is the finished product:

Accelerator pedal

Posted on by

The accelerator pedal in the Bugeye was mounted on the floor board as seen in the illustration below:

Sprite Accelerator Pedal

We have decided to hang the pedal from the shaft rather than mounting it on the floor and we purchased a kit from Speedwell Engineering that has a throttle return spring so that the mechanism is not dependent upon the throttle plate return spring on the carburetor. 

Episode Eighty-nine of the Bugeye Restoration Videos shows the new pedal arrangement installed in the car:

Lighting

Posted on by

Sidelights/Flashers and Tail Lights – We had previously switched the incandescent bulbs in the flasher/side lights and tail lights in favor of LEDs. These are much brighter, consume lower amperage, and produce less heat. This requires replacing the flasher relay can with a substitute suited for LEDs. In our case, the LED flasher relay is incorporated in the Classic Technologies Fuse Box.

License Plate Lights – the original light fixture used two small incandescent bulbs.We converted these to LEDs sourced from Moss Motors.

Headlights – We ordered new headlights from The Bus Depot. Their web site states: “Essentially generic knockoffs of the old Cibie Z-beams, these are tested and certified to meet stringent E-Code and TUV standards.  This means better light distribution and visibility than the cheapo knockoffs sold on Ebay, etc. (which are not E-code and often don’t even come with protective boots on the back). These are direct bolt-on replacements for your stock 7″ sealed-beam headlights; just pop them in and you’re ready to go. They also have curved glass similar to how the sealed-beams looked, whereas most other E-codes have flatter glass that is more common in Europe. (The difference does not affect performance and is just a matter of personal taste, if you care at all.) They also feature a special anti-fogging coating on the insides of the lenses.”

Cibie Headlights

Then we needed to find some LED lights to put in the headlight bodies. After some research we decided on these units from Classic Car LEDs. These were very reasonably priced for what appears to be high quality units.

Driving Lights – We have considered, but not decided on, installing Lucas driving lights. Since it is a possibility for the future, the wiring harness has incorporated the wiring for the lights should we desire to add them at a later date. This image shows what they look like once installed.
