    Basically i found out what the knocking noise was coming from around the engine, the spark plugs had rattled loose somehow and 1 was hand tight. NICE. it happened to me in bristol of all places, sounded fatal so had it towed home to wales where i discovered it wasn't as bad as i'd thought.. untilll the spark plug wouldnt screw back into the thread (just kept spinning). Why do they do this?

    i meant why do they come unscrewed as ive heard of this happening before

    Sounds like the thread is buggered or its popped a few threads.

    might need to get the head Helicoiled (SP) doesn't cost a bomb but a good garage needs to do it. but first check the threads on the spark plug run your nail along the thread.
