Let me start by saying, I understand the risks.
I'd like to see if anybody has pics or knows if the oil screen pickup is viewable through the oil sensor or the drain plug (maybe with a boroscope), before I start down that path.
I've pieced together the belt, and found it is fairly in tact. I'm trying to do a (quick and not too thorough, I know) inspection of the engine without removing the oil pan. The 2011 E70 N55 has had a bad PCV before, and I had already changed out the VC recently, so I am currently changing out the Front Crank Seal. The Front Crank Seal had some pieces of the belt wrapped, but nothing sticking in too much that I can see. I'm getting a "28A0 Intake pipe absolute pressure, plausibility: Pressure too high", which I'm assuming should be the crank seal.
