Oil leak from cam chain tensioner bolt

Chain Tensioner

Fixed today by replacing the washer. Torque is 35nm

Glad it was something simple that could be easily fixed.

Excellent so literally bolt out and back in, that simple ?

Yea, but it wasn't me who didn't, race mechanic did.

He called BMW shop and they explained the procedure to him, but as I understood more or less yes.


Btw, looking at the washer I feel it's not enough torque on bolt issue, rather than failed washer.

Apparently it's a common issue known to BMW who will be replacing tensioner bolt and washer. Some people had it leaked 4 times.

These are the instructions to fit my manual cam chain tensioner if it helps. J

Need to be careful as if camshaft is between positions it can jump when you take the tensioner out.
