Title: no compression on 1 and 2 gti 1.8 turbo
Post by: joeblogs on 14 July 2010, 20:59

Brought car cheap hence fault, checked timing, all good and oringinal cam belt. removed head found inlet valves bent on 1 and 2 and exhaust camshaft bearing nearest pully is worn and head bearing face is scored, yet all others are ok and oily. Also can i fit any other 20v head other than a AUM or has it got to be a AUM?

you need to find out why they have bent before changing the head.. why have they dropped a valve ?? for it to have bent valves in cylinder 1 and 2 you would expect maybe a cambelt snap and piston just slammed into valve which means maybe piston damage aswell..
