Hi Guys, im new to the site have an audi s3 2002 51 plate with a bam engine and need some help. my issue: cylinder 3 has no compression and i need to get it sorted..my current engine is a BAM engine, however i have a 210 AMK engine can i use parts of that engine to fix my problem? are they similar? i have been told i just need the bottom end from the engine. is this correct and can i use the 1 from the AMK engine? would really appreciate any information i can get.
