well some of you mite know a couple of weeks ago i took my saff to AVA to get set up as i had rebuilt the engine etc. all was well untill the last run on rollers the suddenly lost power and car cut out

Got the car started about 20mins later when cooled down but engine was knocking like fook again but as i was 220 mile from home i had to drive it got me home ok ish lol. So today i decided to strip the engine down to have a look and found this





so it looks like my problem is a melted piston first time ive melted a piston on a cossie in 10 year
