M20B28 Engine rebuild
I have a question about rebuild of my BMW M20B28 custom engine.
It's clear in all the manuals that, when rebuilding, you should use new Cylinder head bolts and Conrod bolts as the are 'stretch' bolts and cannot be reused.
My question is about Main Bearing casing bolts. Do these need to be replaced?
I've seen conflicting advice and the original bolts look like bog standard 10.9 high tensile bolts. They are listed on Realoem at only 93 cents which also suggests they are nothing special (especially as conrod bolts are listed at $6.32 each!)
Anybody seen anything definitive from BMW?
