So I've looked in two bentleys and found nothing as to what the tolerances of some parts.

1) piston space from wall

2) all crank tolerances (rods, main bearings, play)

Thanks guys.

I have the PDF version one. Where are the specs, cause I've look through all 800 pages and I must be blind.

Thanks for the help guys.

Here you have the specifications directly from the BMW TIS (Technical Information System)

Sorry, i only have this available in German, but if you spend just a few minutes with it i'm sur you will be able to identify what you need.

But here you have some translations:
General:
* Stufe 1 = First oversize
* Gelb = Yellow
* Gr�n = Green
* Weiss = White
* Kurbelwelle = Crankshaft
* Lager = Bearing
* Spiel = Play
(Kurbelwellenlagerspiel = Crankshaft bearing play)

Img 2:
* Kurbelwellenf�hrungslager = Crankshaft guidebearing
* Pleul = Connecting rod

Img 3:
* Kolben= Piston

I hope this helps you!

Funny cause I looked in the TIS and could not find this.
