N62 misfire

[andrewwynn]

Wow I was prepared to see much much worse. Looks very recoverable.



I was surprised to see any of part #7 at all.



Looking at the reference photos looks like you just had the ala M62 chain guide self destruct where the plastic shoe portion shattered and went into the oil sump.

I would be willing to bet the tensioner was the cause though.

Do you know if the tensioner was replaced with the chain/guides? Havimg done a couple guide replacements, I'm betting if you aren't changing the chain you could probably change the guides without redoing the timing. (if vanos left cogged to the chain you shouldn't need to re-set the timing) just thinking out loud.

Keep posting I'm rooting for you I am quite sure you caught this just in time to save the engine and it's not a huge fix from this point.

Well I think I need to change the chains and guides and tensioners, i guess I have to redo the timing to. I have the tools so not a big problem.
