You get a 22 socket wrench and can't turn the crankshaft.

Engine hook as we call it is the biggest BMW problems here in Nigeria. As we speak my N55 is in the workshop out of the car being coupled back together.
Have you ever done an oil analysis? There seems to be an outside contributing factor... maybe if conditions are very dusty, oil contamination or something? I think you are on the far end of the spectrum not everyone else who isn't locking up engines. PWG bearings could also be a factor, but even still
tell me about it! May be oil contamination down here. There isn't anywhere that offers oil analysis here. I will send pics through tomorrow. Engine is still out

i see about one a month with engine knock or sized engine due to spun rod bearing. most common cause is belt material sucked into oil pan and blocking oil pickup.

Curious, are most of these N55s pneumatic wastegate engines (pre-2014)?
