    Manifold bolts coming loose?

    Has anyone else experienced this?

    Been hearing a blowing noise - like hole in exhaust type of noise for the last few days, and was about to check the exhaust for where, I assumed precat-turbo connection.

    Started my car and saw a bubble of water/oil/air appear by the far left top manifold bolt.. strange I thought.

    Just come to check it, and its excessively loose, ie took 3-4 full turns to re-tighten back up. They were 100% tight before, no question of that, so its weird why only one would come loose?

    Any ideas? problem seems solved now but just a weird one

    hi m8, yep, i had this prob a wee while ago, it sounded like a slipping belt, had it replaced but was still there, eventually it was traced to the manifold bolts coming loose, some had snapped, and some were bent, strangely though the noise stopped when warm due to expansion. been ok ever since.

    yeah mate, similar thing, after a few mins of idle, or a min of driving, all would be well again because the head had expanded the gap shut.

    There still could be a leak there with the exhaust, but cant check again til its cold..

    p.s note to self. Manifolds get v.hot lol! just scoulded my knuckles!!

    no mate, it re-routes cooler water through the turbo for extra cooling/protection, lots of threads on here, do a search m8.
