E60: Cracked lower timing-case - engine finished.

Yeah well that's torn it. Literally, torn it open. After all that effing about with the sump removal, finding the right piston and drilling off those snapped head bolts, I find a whopping great crack in the lower timing-case!



I wonder what caused this? Vibration from the swirl-flap doing its dance? High crankcase pressure from the dodgy piston? Who knows, but we can safely say that's where the oil leak was coming from!

It's a big enough job as it is to replace that single damaged piston, but to swap the lower timing-case as well involves stripping the entire front of the car, getting all the pulleys off and fully removing the crankshaft. Hmm, a lot of work and a lot more cost, this definitely calls for a replacement engine... Watch this space!!
