If I recall correctly 5° is due replacement. I checked some engines well over 500 000km and stretch was 2-3° so it would not bother me much.

Hy ,
Maybe u´re right , but what i really need is the manufacturer info , cause last time i checked it was about 5º , but i never seen or read about the procedure, on how to do it, and i not even talk about valve opening..... numbers
info of MB would be much apreciated....
regards

You do it simple, rotate engine before TDC, take off valve cover and then put 6mm pin into the hole in camshaft bearing. Rotate crank until your pin slides into camshaft sprocket. Then you read degrees on crankshaft pulley, that is your stretch.

Hy starynovy, that is more less common sense,
thing is the other info they talk in the work cards , thats what i´m after .... people say 3 to 5 degrees is good! ok i know that too experience...
what about valve timing , maybe is not so bad ... daddad.
i´m really interested in the work card
thanks

Well it sounded to me like you wre asking how to..
Dont know man, BMW prechamber unit starts to slap valves at some 7°, and noticeably looses bottom end power with each degree beyond 3°.
