Re: Interesting Stromberg problem

Hi Philip, Thanks for posting this, my car has the same issue. I was going to check that the choke plate was in the correct orientation. Is this what you term as the enrichment valve? Now I have another thing to check, would spraying some inert gas around the valve with the engine running demonstrat...

Re: Speed Hump Scraping - Custom Exhaust

Hi Guys Looking at Oles car should be an inspiration to any restorer, hes done such a nice job. My car is at best a good driver. Hi Pete, no I’m not related to the South Island Browns.

Re: Speed Hump Scraping - Custom Exhaust

Hi Joe, The Opus system continued into the early 80s, so you may still have it. In the video title photo you can see a small aluminium ribbed box just forward of the distributor, that’s the opus box. The SNG kit still uses the alloy box but fits the later HEI solid state module in it. Oles exhaust s...

Re: Speed Hump Scraping - Custom Exhaust

The ease of starting is also helped by fitting the later HEI ignition system as fitted to the later V12s. Sng Barratt do a nice replacement with a rebuilt dizzy as well. There is one with the vacuum advance fitted, get that one. If you still have the original OPUS system fitted, watch out, it will f...

Re: Speed Hump Scraping - Custom Exhaust

Ah yes the Joy of Jaguar motoring. Buy a set of Orings for those strombergs, the usuals have them. That fuel drips onto hot bits. Yes I upgraded to the geared starter, a vast improvement. Check out British starters.com there is a different number of teeth for the 1971 engine, check this. Red rubber ...

Re: Speed Hump Scraping - Custom Exhaust

Hi You will probably have to adjust the mixture if you open up the exhaust system. This shouldn't be too much of a challenge for a competent mechanic. here is a link to a you tube video I did of my car with just straight through center boxes and no rear box. https://youtu.be/VaFJJUHjcXk You can prob...

Re: Speed Hump Scraping - Custom Exhaust

Hi Here’s a couple of pics which may be of interest. I did use 2 1/4 inch pipes for my system. The hangers are modified to take modern rubber mounts, available at any exhaust shop. The first pic shows the amount we flattened the pipe under the IRS On the last pic you will see, if you look closely, t...

Re: Speed Hump Scraping - Custom Exhaust

Hi. Living down here in NZ we have lots of roads with poor surfaces, and lots of speed humps. My car used to graunch all over the place so serious intervention was required. I would check your rear ride height, the figures are in the manual. To get it right required spacers under my Koni shocks. The...

Re: Brake master cylinder reaction valve spring

Hi Paul Sorry, I misunderstood where your large spring was. That is most unusual. I was talking about the small spring in the nose of the valve, it’s not shown in the diagrams, but can be accessed by popping the nose off the end of the valve. This is the one that some recommend to replace with a sli...

Re: Brake master cylinder reaction valve spring

Hi There was a solution offered to reaction valve problems that involved fitting a slightly stronger spring than the original. I think it was to ensure the small piston that the reaction valve operates will always return. If it doesn’t you can get sticking brakes. Your spring may be an attempt to im...

Re: Boot Pops Open

hi yes mine used to do this regularly. I found two issues, firstly as mentioned make sure you push the release handle back in after opening the boot. This resets the locking mechanism. The second issue I found was that the locking bar mounted on the Boot lid was not engaging properly with the lock m...

Re: Jagurar E Type S3 on Elevator

Hi Marco My mechanic uses a lift the same as the one pictured. For the front we use the jacking points as fitted to the car. Just put the rubber pad a little off center to get a clear lift. For the rear it is a little more difficult. You cannot position the rubber lifting pads on the jacking points ...

Re: Timing setting for vacuum advance V12

Yes all vacuum disconnected.
I also run a 5 speed and a 2.88 diff, which the V12 handles effortlessly.
As far as the extra advance goes, why don’t you email Ron at British vacuum and ask him. He is very approachable.
Cheers

Re: Timing setting for vacuum advance V12

Hi Simon, I have a very similar setup to you. The only difference being the use of the SNG HEI ignition amp, from the later V12s. I went down the Opus, reopus Path till finally arriving at the HEI amp which has been superb for a number of years, but I digress from your question. I have the same adva...

Thanks Rosco
That’s a relief, I didn’t want to change things. I’ve been running like this for several years with no problems.

Re: Series 3 V12 Running Hot

I’m now confused about the current draw of the fans on high speed setting. Ole posted some figures quite a while ago that showed each fan drawing 12.2 amps on high, so a combined total of 24.4amps was within my 30amp relay. Since then another poster came up with a much higher figure, well over the 3...

Re: Series 3 V12 Running Hot

Thats a very nice job you are doing on your radiator area.
I may have to modify my relay setup to yours, as I have only got one relay for both fans on high speed, and thanks to another poster I found out the amperage draw is way above the relay rating.

You have covered all the weak points with the rad rebuild, coolcat mod, the otter switch upgrade, and a manual override switch. If you want fu...

Re: Rad Rebuild

Nice job, I did the same mod with the VW fans.
Use relays to power the fans when you wire them in, you probably knew that, theres been lots of threads on it.
On high they pull quite high amperage.
Cheers
