Re: Mystery vacuum port

Oddly, my service manual shows the static timing as being 12deg BTDC and 4deg ATDC at idle. That's very interesting, Ive never heard of that before. Is it something to do with having the retard unit connected, although I understand that it only puts in around 8 degrees of retard. My manual is the bl...

Re: Mystery vacuum port

John I use 12deg before tdc, for idle timing with the vacuum unit disconnected. This is specified in the service manual under the electrical section. Do check your dizzy has movement and kick back when you turn the rotor a little way. Many get seized up internally from lack of lubrication down the c...

Re: Mystery vacuum port

Hi John The advance or retard module is the silver unit on the lower side of the distributor. If it is operational it is connected via a vacuum hose to the port on the carburettor that I mentioned. Many people have just blanked the port on the dizzy if the unit has failed. You can tell if it is an a...

Re: Mystery vacuum port

Hi guys Yes that's correct, that port had a vacuum line to the flap in the forward portion of the intake trumpet on the carburetted cars. I also have disconnected mine, and just blanked that port. There is one on the other side as well. Its not for the distributor, that vacuum comes from the LH rear...

Re: S3 with 2.88 diff

Hi Phillip. My car has the 2.88 plus a getrag 5 speed. At our speed limit 100km/hr it shows 2000rpm, this makes it great cruising still with leisurely overtaking. The best thing about this combination is the need for plenty of gearchanging to drive the car properly, especially when things get twisty...

Re: Changing Rearlight from US-Spec to Euro-Spec

Hi Guys
Just got Mareks's tailights fitted today. They are an excellent product, well made, and fit well.
His covered headlight mod for the S3 is also very well made, and in my opinion the best on the market.
Cheers

Re: New clutch

Hi You will need to either take the engine and gearbox out as one unit, or make a modification to the tunnel to allow you to get the gearbox out on its own. Cutting out a piece of the tunnel seems a worthwhile modification to me, even though some would say its sacrilege. I did mine then took the pie...

Re: Fuel pump not working after winter

Hi Georg
My car is a S3 so I'm not the best person to ask for your questions. However If you google for pictures of jaguar S1 fuel pumps there are plenty of pictures.
The cap is at the end away from the main pump body. The points inside look very similar to the ones in your distributor.
Cheers

Re: Series 3 etype 2+2: cooling system

Hi Chris I did use distilled water when filling mine, I cant give any decisive reasons for doing so, but thought its a new rebuild lets keep it pure. I have not heard of using hylomar on the heater hoses, I only use some red rubber grease when fitting them. I have never had any leaking in this area....

wiper arm lenght OTS

Hi Guys
Could someone kindly tell me what the correct length of the wiper arms is on a S3 Convertible.
Its measured from the center of the spindle to the end of the wiper arm.
It looks to be somewhere from around 280mm to 305mm both sizes I can get down here.
Many thanks

Re: Thermostatic Vacuum Valve and Retard Unit

Sorry I'm late to the party on this issue. In answer to some of your queries. I ran my car with the vacuum retard disconnected for a number of years, no issues were observed. My car is a naked V12 with no emissions pipework, no valve fitted. As part of the rebuild I did exactly as British vacuum rec...

Re: Fuel pump not working after winter

I have heard stories of the pump points getting a little corrosion on them over winter. Pull the pump, take off the Bakelite or plastic cap and clean the points with emery paper. They are what gives you the tic tic when power is on.

Re: Sheared otter switch bolt

Hi Guys
If you are looking to upgrade to more modern/reliable componentry, check this link to Coolcat out. I fitted one to my V12 several years ago; replacement senders are a modern readily available part from Porsche.

Re: Thermostatic Vacuum Valve and Retard Unit

Hi Guys I have a 71 S3 with strombergs. I used the british vacuum unit timing and distributor curve advice, also the recommended vacuum advance module. I got Rob to recurve my distributor to his spec. He also drilled the carb for ported vacuum at a very reasonable cost. He has made a jig to get the ...

Re: Lying "Battery Condition" / Volt meter

Good post, thanks for that. I have just upgraded the alternator on my S3, and am experiencing similar symptoms. I think heat might have also had an influence. After a 3 hour run with 30 minutes of stop/go at the end, in warm conditions, I noticed the voltmeter at 12 volts or less, dropping into deep...

Re: Optimising the V12

Hi Guys
I made a slight error in my original post . The vacuum retard port comes from underneath the carb, and the advance port is on top of the carb.
By the way you can get advance ported ZS carbs from some of the XJ series cars.

Re: Optimising the V12

Hi Guys Just to add a little fuel to the fire on this topic. My car had a retard vacuum unit on it, which I decided to disconnect. The car ran fine but obviously sub optimally, as there are times at part throttle when more advance could be tolerated. Searching around the net I found a guy in the sta...
