Re: Myths concerning the V-12

Hi Atle, I'm another happy V12 owner, manual car, with Strombergs. The above advice is spot on, I wish I had taken it when I purchased mine, nothing serious but issues I could have negotiated price on. Do you have a Jaguar owners group anywhere near you. If so get in contact with them and you should...

Re: classicfabs exhaust system

Hi, There are some question marks over the performance gains from these systems. Also some people don't like the tinnier sound from stainless steel. If you search for posts from Woolfi he has done lots of work around carbs, bigger bore exhausts, and the advantages disadvantages of fitting EFI instea...

Re: V12 Stromberg Bypass Valves

Hi Colin I reckon the best fix is to just block or blank off both types and enjoy the lovely little pop pop pop as you decelerate, sounds like a sports car should. I saw the nice little blanking plate you made up, but it was above my skills, so I just cut out a piece of solid gasket paper and replac...

Re: Ignition Amplifier

Hi Andrew I also found the following diagram of the internals of the Ballast resistor, or not. There is no guarantee of its authenticity, but it should be simple enough to test it. https://s8.postimg.cc/a0o44whz9/IMG_3637.jpg the resistor numbers are A-D 6.8K ohms B-F 0.3 ohms Cheers Mark

Re: Ignition Amplifier

Hi Andrew Whilst surfing the net I came across the attached diagram. It may be a useful test, perhaps one of our electronics gurus could comment. The coil supplied with the SNG kit is a Lucas DLB 198, which advertises as a 0.8 ohm resistance and suitable for non ballasted systems. I have read somewh...

Re: New Exhaust manifold - bad fit

Hi Hilton Those older manifolds do break the ears, where the studs go through. I’ve had two go, and they are a pain in the arse to change in situ, as you are finding out. I think This is why the newer ones are thicker. I bit the bullet and changed out both on the same side for new ones which made th...

Re: New Exhaust manifold - bad fit

Hi Hilton I had a similar experience with fitting two new manifolds to my car. Firstly get the pair milled flat as a pair. When fitting leave the manifold slightly loose then fit the lower down pipe and then tighten up the manifolds. Next check that with the studs in the block that there is enough s...

Re: Vacuum Pipes on series 3

Hilton
The Sng distributor has a vacuum retard unit as per the original set up. Just blank it off,and the port under the left hand rear carb.
You don’t need anything connected to the port under the carb.

Re: Running Temperature etc

Hi Colin, the distributor vacuum unit never connects to the carburettor bypass valve. If you hold to the Jaguar method it is either connected to the port on the top or the bottom of the left rear carb depending on whether you have an advance or retard vacuum module fitted. If you want to run with Ph...

Re: Vacuum Pipes on series 3

Hi Guys Just an idea for some of you who don't have the ported vacuum carburettor with the port on the top for the vacuum advance module. Quite a few other jags of similar vintage used the same carb with the correct advance porting, im thinking of the jaguar saloons XJ6 series, or some of the later ...

Re: Running Temperature etc

Hi Colin, I do agree with Philip regarding the vacuum retard module on your distributor. Just disconnect it and plug the port on it and the manifold. Your car will run just fine without it. For some unbiased advice on suitable vacuum advance modules take a look through this website. www.britishvacuu...

Re: Running Temperature etc

Hi Colin, Regarding those thermostats. One of our posters,Marekh, did an interesting research project some years ago where he discovered that most, if not all replacement thermostats available today did not open enough to close off the radiator bypass inlet, leading to hotter running. So you may fin...

Hi Hilton
I would start by ringing SNG.
A quick google search for stromberg mixture adjusting tool yielded several UK suppliers.

Re: Starter motor not disengaging

Hi Guys, I’ve got an early V12, fitted with what appears to be the same starter as in the posts, although I got mine from British starters.com in the US. The starter has been on for 10 years with no problems. It is a close fit but does not touch anywhere. I pulled the engine for a rebuild a year ago...

Hi Guys Ole, the relays I used are the 5 pin version with the extra 87 terminal, but we didn’t use it, so thanks for your input, others will benefit. I would be interested to see how you wired up the delay relay. Here is a pic of the 2 relays on top of the radiator. Yes, I have put in an alloy radia...

Re: Starter motor not disengaging

Hi Yes it’s easy enough to change the starter motor. Drop the splash guards under the starter motor, then it’s easy enough. Don’t bother to repair the old one. Just buy one of the modern geared type, Japanese manufacture, bearings instead of bushes, much better cranking, and half the weight. It will...
