Re: Ported Vacuum Source

The factory fitted retard unit makes the spark fire closer to TDC and the purpose was to make it warm up quicker,burn hotter at idle and meet better emissions. As soon as you take off it is inoperative as there's not enough vacuum to power it. Early cars had a temperature controlled vacuum valve tha...

Re: Thermostatic Vacuum Valve and Retard Unit

All of my car is standard UK spec with PJ Langford SS exhaust. I'm sure it can always be improved but with the torque it runs great at last with no flat spots. I'm sure lamba information would improve it but you'd be amazed how using an air flow meter on the carburettors highlights imbalance when se...

Re: New clutch

I've done it with no cutting on my S3 without removing the engine but what a pain. You have to drop the rear end down to pull the prop back more. Cant remember about the exhaust. Remove interior tunnel, disconnect bell housing and pull back, You need good socket set and extensions, undo the pressure...

Thermostatic Vacuum Valve, Retard Unit and overheating

Finally got it running pretty well. Cooling system stripped out and found loads of old Bars Leaks cork plugs. Ignition replaced and with coil relocated to outer wing area for cool. operation Multiblade cooling fans fitted. Carburettor temperature control valves were making car run weak so they were ...

Re: Difficult start - only when heat soaked E-Type

I have fitted a translucent fuel filter on the downstream side of the valve. This enables me to see the fuel flowing when ticking over. I suspect there's just too much heat once left and the inlet manifolds are vaporising. I try to switch the fans on before I stop the engine to cool things down a li...

Re: wiper arm lenght OTS

Interesting because my drivers side RHD wiper overlaps the windscreen chrome pillar at the bottom right .when parked.
Seems to me the wiper blade should be shorter but they all seem like that?

Re: Thermostatic Vacuum Valve and Retard Unit

I have now completely taken the valve out of the system. In addition due to rubbish leaking retard units out there I have excluded and plugged the pipe and unit. I may do vacuum advance later but road trials are optimistic.

Re: Sheared otter switch bolt

Looking good. I too sheared one of those bolts and as mentioned drilled it and got in a stainless self tapper.
It's also nice to have a switch with light to activate the fan relay and thus switch them on manually in traffic.

Thermostatic Vacuum Valve and Retard Unit

I have now completely bypassed the valve and run vacuum direct to the retard unit from LHR carburettor. I purchased it recently from Jag Shop and although it works it now leaks slightly. This I have verified with my trusty big plastic syringe and it doesn't hold vacuum. I will at some point remove i...

Re: Stromberg Carburetor rebuild V12 S3

Be very careful on the outsource. I paid £600 to a well known Carburettor company in the 'Southern' part of England. Their work had left me spending hours and hours of tracking a fault that they should never have done. I have spent so much time trying to find out why my car was running awful when ho...

Re: Thermostatic Vacuum Valve and Retard Unit

The reason why I made that statement was that I fitted a vacuum gauge by means of a tee piece into the vacuum supply to the retard diaphragm. Timing was set according to the book. I also had a strobe pointed at the timing marks. Car ticks over and vacuum is high, blip the throttle and vacuum is low....

Re: Thermostatic Vacuum Valve and Retard Unit

My engine number is 7S 5099SB,1972 model. I'm now beginning to think that most people have either junked the retard connection and plugged the carb or bypassed the thermostatic valve and run vacuum direct. If this is the case surely the car is running artificially hot at tick over in all conditions....

Re: Thermostatic Vacuum Valve and Retard Unit

To fit an advance unit I would need to drill the carburettor and make a tapping as the source needs to be local to the butterfly, not something I wish to do at present. The only advance on the S3 V12 E Type is through the centrifugal weights inside the distributor. The RETARD unit was fitted to the ...

Thermostatic Vacuum Valve and Retard Unit

My car is a UK spec manual. I bought it when it was 5 years old. It is fitted with the valve at the rear of the RH inlet manifold bank. I seem to remember that when I purchased it there were some pipes connected to it but not all. I presume some were removed or never fitted,little brass pipes carbur...

Re: Misfire/Backfire/Low Power Issues

I think you've had a lucky miss and hope it was just as simple as that. Having battled with this issue for months/years and now nearly solved the issue I suspect your ignition is breaking down due to heat. Heat is an issue in itself especially if you have older Opus ignition and even replacements. T...

Hello to all, I've messed around with Jaguars for years and have owned my present car since 1978. It's kind of been off the road for years but I've always been doing something to it in bursts. Probably had most things apart over the years and had a lot of bodywork done in the mid eighties. I've fall...
