"From my Haynes manual:
Rod bearing journal diameter for 6-cyl VANOS engines:
Standard 44.975/+0.016mm
1st undersize 44.725/+0.016mm
2nd undersize 44.475/+0.016mm
Bearing shells are in RealOEM here:
http://www.realoem.com/bmw/showparts...19&hg=11&fg=20 Rod bearing running clearance measured with Plastigage is specified at 0.010-0.052mm.
If you're doing engine work I strongly recommend getting the Haynes manual, since it has engine and other internal parts information and methods that Bentley apparently thinks we don't need. Since only it only goes through the 95MY and is for Euro models (M3 not included), you do need to pay attention to what it covers and whether it's applicable to us, but the core info is good.
