I've scoured the engine put magnetic tool round every nook and cranny, drained the oil and the shim is nowhere to be found.
I put a spare shim in that I had lying around so I could measure its clearance, measured in at 0.422mm, spun engine round by hand a few times and it went down to 0.391mm, spun engine a few more times and was down to 0.385mm.
So question is if I continue to spin the engine/crank it over on starter without starting is it likely to bed in (if thats the right term to use) and return to a reasonable clearance or is it completely knackered and if so whats the easiest way to go about fixing it?
