DDK - Die Deutschen Klassiker

Ok so when I did the tappets when the engine was out I was in a quandary about finding TDC. I’ve got the Z1 mark on my pulley so that’s fine it’s just that I can’t easily tell if it’s on the compression or exhaust stroke I don’t have a distributor any more so using the position of the rotor arm is a...

Thanks Tim. However they actually are new spark plugs. That soot is after two trips of about 5 miles.

Out of interest what hotter plugs did you switch to?

Now the deadline for the Pyrenees holiday has passed I’m enjoying this analysis process much more

Thanks - they are both interesting thoughts and things that I can check on I think the HT leads are OK. They are perhaps 10 years old and seem to be good quality and in good condition. They are also producing spark to the spark tester I agree that if we’ve got fuel before the injector and spark in t...

Thanks - might leave that until tomorrow (though I’m getting better at removing the fuel rails now) I”m not sure it’s that whole bank - that wouldn’t explain why number 2 was 20 degrees cooler than 1 and 3 - to me that would be more of an indication that 2 isn’t firing but 1 and 3 are and the cooler...

Thanks mate. Good to know I’m in the hands of experts here.

So fuel then. I know there is fuel in the fuel rail (would t start otherwise) I removed the left hand fuel rail https://uploads.tapatalk-cdn.com/20240525/5753eafabdd2bf2da5c67851f06d63bd.jpg Unlikely/impossible to be a block in these holes as they are so big, but I blew them through with an airline ...

OK so then I connected an inline spark tester to make sure spark was getting through

So it is producing spark to the plug

I suppose fuel is next

Ok so I took no 2 plug out https://uploads.tapatalk-cdn.com/20240525/89a59d417a4f0d7f693d8a8118fbb351.jpg Bearing in mind this was brand new and I’ve driven it round the block a couple of times it seems unusually sooty. So I grabbed one of the previous plugs, cleaned it up and put it in. Started it ...

I’d worried that the ECU problems hadn’t been fully fixed but thinking about it, the ECU sends a signal to one bank or the other - if it was ECU related then I’d be getting nothing on one bank. So it’s fuel or spark on No 2 It’s got a new loom, new injectors and new spark plugs. I say new, but the s...

OK so the saga continues… The new injector loom arrived. However it wasn’t marked as to which set of injectors was on which side I referred to the wiring diagram https://uploads.tapatalk-cdn.com/20240525/23bca082058667a024b75aa783757f22.jpg And peeled back the boot on one of the connectors. Sussed o...

Yes when we stopped in the afternoon we were all actively helping Gary trace the noise https://uploads.tapatalk-cdn.com/20240524/00a32dbb5c85096cb0d7d72f74803371.jpg Just to be clear the GT4 was incredibly capable but I was taking the corners in 2nd not 5th. I would far rather have been in my backda...

First (unsuccessful) go at fixing Boydys fanbelt

That’s the AC condenser that Jonny is talking about

Interesting…
