Thank you search button! I've been having troubles with the A14 over the past couple of weeks, I changed the plugs on a 9th of November (night before I had to travel 120km to a rallysprint) The no.1 plug looked terrible, the others seemed to have more normal signs of wear. It was like and oily sooty buildup on it and the plug was also built up like it was rusty? Put some older plugs in as I had nothing else and I knew they were reasonably fine. During the course of the trip the motor behaved like the one mentioned in the first post and whatnot.

just yesterday I pulled the plugs out to have a look and to my suprise no.1 2 and 3 looked like they have been in rusty water for ages and no. 4 was covered in oil and the plug had a gap of about .2 or something shocking!.

I did a compression test and cylenders 1& 4 were reading around 125psi while 2 & 3 were just over say 130 or the next little bar past 125. I also did a carbon clean for a few minutes to try and rid the cylenders of some of that crap aswell as a quick timing check.

Would any of this be the signs of broken oil rings or a broken headgasket? there is an airleak somewhere I must find on it too but I have a feeling it may be the carb or intake causing that one.
