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...

Re: V12 Oil pump

Hi You will be surprised how long it takes to prime up the oil pressure spinning the engine over with the starter motor. I have just rebuilt mine, and it took a couple of 15sec bursts with the starter motor to get oil pressure showing. No pre priming was done. My mechanic didn't see any problem with...

Re: 73 USA S3 2+2 Won't Start

Be careful with the ballast resistor test results. The SNG kit uses a non standard one, I'm not sure what the numbers should be.
Perhaps someone could test one and post them.

Re: Lost power and hear air bubbles in fuel tank

What about sediment in the fuel tank drain. If this gets stirred up it may be creating random blockages.
You could try removing the bolt and see what comes out.

Re: Solution to use a latter V12

Hi
Did you look at the price for a refurbished V12. At 4400GBP it looked very good value for money, depending on what parts were reused.
Having just spent at least double that on my rebuild, mostly new internals, I wished I could have access to a rebuild at that price.

I just had the first drive with the extra spacer washer fitted as in the above posts.
What a difference, there is none of the driving on ice twitchy feeling any more.
A great modification

leaking steering rack

Hi I think the price sounds very reasonable. Down here in NZ it cost me around 400 quid. As far as rebuilding goes we would have to do it down here to pass the annual safety inspection. Woolfi's idea sounds simple enough. I was in the process of rebuilding my pump so I took the jaguar approach and f...
