i got this 109 block down to bare block .but noticed when i pulled cam out it had worn into block and shim was thrashed...this was a flat tappet cam with roller button on it....my question for some of the more experienced members is this......
1..does a flat tappet cam take shims behind it?
2.is it possible the cam button spring was pushing cam back causing the wear (no end play in cam)?
3.and how bad is this wear?
