    Default 3.2 GSi - smoke under bonnet, BEWARE !!

    Tonight I thought I'd have a look from a distance to see what my xenons looked like. As I walked away from the car, I could see hazy smoke in the headlights.

    ****, so lifted the bonnet and could smell something like burning rubber. Shone a torch around the engine bay and noticed the smoke was coming from the bulkhead area, somewhere by the rear exhaust manifold (V6 remember). The smell was now like oil on the exhaust manifold. The smell was worse when you revved the engine. Never thought I had any oil leaks but found oil leaking from the back rocker box cover.

    "How come" I think, so decide to check the torx bolts on the rocker cover, or at least the ones you can get to without taking off the inlet manifolds

    There were three bolts I could get to easily at the rear, two could be tightened a bit further but the third one was about to fall out!! This would explain that when the engine was revved, oil would be forced out under pressure.

    Tightened all three bolts, no more smell

    Might be worth other 3.2 owners just having a quick check to check for the same before things get worse.

    It wouldn't be a Vauxhall without oil ****ing out of it somewhere.
