Knocking

wonder if it's preignition caused by loads of carbon....
have you tried running it on 97?

we was at matlock as well, at the fishpond

did you spot the camera van on the a6?

 

Just looked and ur a bit far away for me to have a listen mate. u dont work up this way (preston/blackburn) or regular travel up here. id be more than willing to bomb out meet you somewhere and have a listen myself. very hard diagnosing noises off descriptions lol

 

We saw it - a bus flashed us from the other side as we were getting close (which was unexpected and nice) - Off to matlock again tomorrow, the weather looks nicer.

I have tried 97 for a few tanks.. does not seem to make a difference..

 

I work in Wigan... might have to arrange something
