Re: LED bulbs.

I agree that H4 LED bulbs are finally getting close to acceptable whereas up until now they've been poor to diabolical - particularly for blinding oncoming drivers. As you say, the size of the heatsink is a challenge. Have you seen the recent thread on JL where someone has posted some comparative me...

Re: Cooling Fans

It is relatively easy if not a bit fiddly to replicate replacement brushes from generic 6mm x 6mm carbon brushes and crimp them (gently) back in the steel brush holders.

Re: S11 Cooling Fans

There's a picture of the thrust washer in Chris Vines' restoration thread:

When I rebuilt my motor the washer was steel iirc but I can't be certain.

Re: Two carb set up

It depends exactly which two carb Stromberg setup you have but there is actually very little for your mechanic to play with - that's deliberate so folks couldn't mess with settings to upset the emissions. As said, you need to hold the secondary throttles permanently open and apart from balancing the...

Re: Malpassi fuel pressure regulator

This certainly is a solution looking for a problem.....

The irony is that the SU pump as standard on an E type has - effectively - a filter king pressure regulator already built into it :wow:

Re: Insulation on exhaust hoses

Yes but wouldn't you have had the fire whether the pipes were wrapped or not? If hydraulic fluid sprayed in the direction of the exhaust pipes it would catch fire.

Re: Brake issue

3) Incorrect master cylinder push-rod length clearance (1 hour job) (5 min job) there is a bolt at the rear of the pedal box housing that sets how far the brake pedal returns. You need to adjust that bolt to allow the brake pedal to return far enough so that the brake master cylinder is fully retra...

Re: Dodgy coil?

When you fit a set of electronic points such as a Petronix, Simon BBC or similar they open more quickly than a mechanical set of points which is deliberate and beneficial as this faster opening gives a steeper rise time and a higher voltage spike from the coil. It's one of the two ways electronic po...

Re: S2 fhc - aircon renovation

It will be a journey of exploration - I haven't done it on a Jaguar, only on similar cars of '70's vintage. When you say completely as is you need to consider the following: That your original compressor still works, isn't seized or leaking. Check the magnetic clutch works and pulls in. The system h...

Re: Gearbox Oil Change

In all probability for your car the access hole in the transmission tunnel is on the wrong side so it is best and probably easiest to drain and refill the gearbox oil from underneath as long as you can raise your car into the air whilst keeping it level. From underneath both the drain plug and the ...

Re: Insulation on exhaust hoses

Yes, I have had that but the insulation only retains a small amount of moisture if you get it wet and it steams off so quickly as the pipes warm up you don't notice it so I'd say it's not a problem.

Re: Which 185 tyre: Dunlop or Pirelli or Michelin ?

I bought 185 Vreds and have been very pleased with them. They would certainly save you a lot of money over the tyres you propose.

Re: Insulation on exhaust hoses

I've done exactly the same on my car and it works well. Yes the heat has to go somewhere but into the exhaust boxes where there's good airflow on the move and then on out the back is better than into the engine compartment.

So you did have a good idea :geek:

On E types the problem of easily stripping the sump plug thread comes from Jaguar using an aluminium sump and a UNF thread.

Re: Servo assistance for the clutch ?

Has anyone done this? 1.9 or 2.1 to 1 in line servos are readily available so I'm up for some experimenting.

The other option to help make the clutch action lighter is to fit a .625 clutch master cylinder. Apparently MarekH has done that on his V12.
