BMW Plastigauge Taper?
Checking rod bearing clearances on an S54B32 I’m rebuilding and on bearing 2 the plastigauge is coming out wider toward the front of the engine. I’ve double checked there’s no debris behind either bearing half, and the plastigauge is within spec along the entire length. Is this something I should worry about? Not looking to make any crazy with power with this engine, keeping it stock and mostly to be used for daily driving.
