Re: 5 speed gearbox

The Tremec box should be very smooth in operation. If it's feeling notchy, it may be knackered or simply due to incorrect fluid. The correct fluid for a Tremec 5-speed gearbox (like the T-5, TKO, or TKX) is Tremec HP-MTF, or a high-quality Dexron III/Mobil 1 Synthetic ATF. A lot of people get this w...

Re: Oil over fill.....spin on adapter

I've had spin on adapters on all three of my E-types, and also on several MGs, a couple of Triumphs, and even my Singer. None had 'one way valves' and FWIW I've never seen or heard of such a feature on any spin on adaptor . Now it is true, and somewhat common for spin on oil filters to have an anti ...

Re: What's it like living with a moss box?

I've had two Moss box cars, and now my current 4.2 car which I converted to a 5 speed a year or so after purchase. I've no quarrel with a Moss gearbox in an old sport tourer.

Is the squealing somewhat muffled (as it would be for an internal issue)? Or more of an 'external' sound?

Re: Bars leaks

A chemist friend recommends reverse osmosis (RO) purified water for engines with aluminum (aluminium :bigrin:) and specifically against 'softened' water, due to the ionization brought on by the salt in a typical softener system. In the U.S. at least, RO water is easy to find in gallon jugs at most g...

Re: Brake pedal adjustment

For large pedal position changes on these early pedal boxes, I absolutely agree the best way to approach this is to remove the pedal box. I managed to do it in situ on on my first E Type, but was young and agile then. On my current car, when dialing in the pedal heights, it took two tries to get thi...

Re: Cooling hose replacement

I would say no. The silicone hoses can last pretty much forever. Good quality non silcone hoses can last for decades. So lifespan really isn't an issue with these cars typically doing single digit thousands of miles per year. Silicone hose typically has a gloss type of finish, often with a wrapped t...

Have you checked out the header tank from Cambridge Motorsport? It's a thing of beauty and can be ordered with choice of thermo switch bosses, and either polished or satin finished. I bought polished, but found it a bit blingy, so had it powder coated satin black. https://tinyurl.com/Cambridge-Tank ...

Or just use copper or aluminum crush washers on the banjo bolts. No soaking required. Tighten once and you're done.

Re: Exhaust lengths

I had forgotten about the so called extractor opening in the rear hatch on the S3's. The slightly humpback shape of the +2 suggests to me that airflow over the rear hatch would tend to detach and create a turbulent area towards the lower part of the hatch, similar to the the 2 seater FHC but beginni...

Re: Aftermarket heater fan internal short

Overflowing carbs are much more likely due to a varnished (gummy with fuel residue due to lack of use) or worn needle valve. Floats do leak and 'sink', but that is relatively less likely to occur.

Re: cooling fan

That crusty fan is no doubt an improvement over the original item, but its small diameter blades relative to the fan shroud is leaving airflow on the table. Best performance will come from a multi blade fan with a diameter slightly smaller than the shroud, i.e. Cool Cat. My otherwise stock S1 4.2 ca...

Re: oil sump draining before working on oil return???

If you have access to a car lift, no, it is not necessary. If you place just the front wheels on the lift and raise it, the car (and engine) will end up at an extreme angle and the oil level will clear the return pipe. I replaced mine this way. While you may have lived to tell the tale, I would hig...

I would replace braided rubber based lines at no more than 10 years old, regardless of mileage. And if you have no idea how old it is, I would argue for replacement.

Re: Voltage across coil terminals

I believe the "lost"voltage is powering the coil (which is basically a transformer). Disconnect the negative wire from the coil (keeping points closed) and measure the voltage between the coil positive and the negative wire. Should be nominally the same as battery voltage. If that is not the case, y...

Re: ZF 8HP 70 box swap

I would think the 8HP with its two OD gears (8th gear around .64 from Wikipedia) would be a step too far with a 2.88 rear end, yielding a 1.84 overall ratio in 8th. I think it rare to see a car with an OA ratio below 2, and there is a reason for that. You might find a car with the dynamic characteri...
