Member Post nr. 408 KL, Malaysia e21 323/6 316, e34 520i, e32 730i	Hi, Here's info about my M10: Model E21 Type 316 Spec ECE Steering Right Transmission Manual Engine type M10 Produced Apr 1980 From Jeroen's there are few valve clearances for the same model: M10 in out(mm) 4 cyl. > 81 .15 .20 316 81> .20 .20 Should I use clearance of in/out of .15/.20mm? I think pre-81 or 316 >81 is 1.5L M10, whereas post81 316 is 1.8L.. so 316 81> is really should have been 1.8L M10... Am i talking to myself...

Member Post nr. 650 Helena, Montana none right now :(	I adjust M10's to .08" thats assuming you have a stock cam, with a high lift cam, I use a slightly greater clearance, usually about .10" I find that .08 works best for most M10 applications, any tighter than that and it starts getting too close with the risk of burning a valve
