Hello Bart,

thanks for the update. That's definitely not good. I took a look at the video and noises again. Think the bad engine has to be disassembled completely. Check the connecting rod bearings. Do you know if the car was used for racing?

Hope somebody can supply you with a good replacement engine.

Regards, Markus

It will be interesting to learn what initiated the carnage.We can learn from the post-mortem even if it is just one of the classic "Modes of Failure" for the M96.
What failed first?
1. Did the oil pump drive shaft fail ? upgraded part availble from LN
2. Did the chain ramps disintegrate ? known weakness
3. Weak chain tensioner(s) + over-rev ? age/abuse/low oil pressure
4. Stretched chain(s). known weakness on older M96 for which upgrades are available
