Re: V12 2+2 Coupe converting to DHC - Feasible?

Hi Phil to get back to your original query. Yes its possible, I had mine converted almost 30 years ago. At the time I didn't have the money for an original softop so this was the only option. The good thing about the S3 2+2 is that it was designed as an open car so all the chassis and body is up to ...

Re: Vacuum pipes

Or if the vacuum advance mechanism had failed, a common complaint, then some owners just blanked it off, and the pickup on the carb.

Re: Brake Pedal Pressure Drops?

Hi
The normal cause is some air still left in the system.
Get your mechanic to rebleed the brakes.

Re: Vacuum pipes

Hi I think you will find that a PO will have got rid of emission control gear. On the stromberg there is a temperature controlled bimetallic device on the side that can be vacuum controlled on some carbs there is also an overrun enrichment device also vacuum controlled that is often blocked off. If ...

Re: Tuning Problems V12

Hi Mike,

I took a look at that plug on my Pre HE barratt distributor. LIke yours it seems to cross over the wires, however it works perfectly.
No guarantees with your HE dissy, but it may be correct.

Re: Tuning Problems V12

Hi Mike Very frustrating. I have the SNG barratt opus replacement system on my V12. I have had it installed for 5 or 6 years with the amplifier in the valley the same as yours, it has not shown any problems. However the symptoms you describe sound like the failure mode of the original OPUS amp, so i...

Re: S3 V12 Stromberg/Dizzy vacuum pipes

Hi Ryan,

If it helps I am also using the HEI ignition on my 71 carby V12. I have set the base timing to 12Deg BTDC, and there is no hint of pinking or knocking.
Down here in NZ we have 95 Octane RON fuel, which is very similar to your US 92 octane

Re: Hello from New Zealand's newest member

Hi Guys, Welcome to Jaguar world. I’ve been doing stuff to my S3 for around 15 years, and there are plenty of top resto guys available down here in NZ. We do have Beachams in the Hawke’s bay who are world class. I had the mighty V12 partially rebuilt a couple of years ago, and would recommend Taylor...

Re: s3 butec to alternator conversion

hi Rob
I have a page of instructions for a Denso 110amp, internally regulated alternator, they came with a kit that I bought from SNG Barrett's.
PM me if they are of use.

Re: S3 V12 Stromberg/Dizzy vacuum pipes

Hi again One other thought regarding distributors. Jaguar, after a couple of distributor cap explosions, due to vapours leaking into the cap, changed the cap to a vented one. These are available thru the usuals, and have two ports on them, one is connected to the rear of the air filter canister to p...

Re: S3 V12 Stromberg/Dizzy vacuum pipes

Hi Looking at the picture of your distributor I’m fairly certain that it’s the HEI distributor as used in the later V12s. It looks so new inside that I’m thinking that it may be the unit sold by SNG Barratt, if so it has the upgraded electronics packaged in the original Opus box which is visible in ...

Re: s3 starter motor removal

Hi I agree on removing the tunnel access panel. I don’t remember the clutch line being an issue. I also removed the battery and it’s support box. If you are removing the starter due poor performance, check out the geared starters available. Half the weight Faster cranking Lower current draw Half the...

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: 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.
