Thread: Little help with an oil leak diagnosis?

    Little help with an oil leak diagnosis?

    Hey guys
    Discovered an oil leak down the front of the engine on the exhaust side.
    (Made a big ol' mess).

    Would this most likely be cam position sensor or vanos gasket related?
    While cleaning up the mess I noted that VCG looked good. It was replaced about 20k ago.

    Picture taken from below looking up:

    I'll leave this up just incase anyone ends up searching in the future.

    It was the cam position sensor o-ring that was bad.

    Your pic didn't post. Can you repost it to help the next buddy with a leak on that side of the engine (kinda rare compared to the classic spots, OFHG and VCG).

    Weird. Edited and uploaded rather than inserted now, hopefully it's working.
