All sorted!!!!
It was as most of you thought.........the Cam and Lifters!
3 out of the 8 lifters were so burred over that i had to drop them out the bottom becaue they would not come out the top!! Chunks missing, Cam lobes burred, looks like it's all been hit with a hammer over and over again! All in less than 150miles!!!
Piper back in now, all good as gold!
