engine rattle

   excluding the chugging, it is noise free when cold. it does only seem to be the motion of the engine causing the rattle.
as a further development, it actually seems to be the underneath of the car that the noise is coming from. it seems to be the driver's footwell, actually. i had my back box changed recently and it didn't do much to change the exhaust volume. could it be the cat maybe??

	A knackered big end first shows upas a knocking on cold starting before the oil pressure has built up. Is there any evidence of this? TBH I would get the MAF sorted out first then see how it sounds. I wouldn't worry too much about noises it makes when it's only running on 3 cylinders. Get it running on all 6 before you start worrying about other things.

	due to a dicky MAF sensor, my car will regularly run badly. when starting from cold, it seems to run on three cylinders for about a minute, then splutters and runs perfectly fine with no other signs of ill health. however, while waiting for the engine to come right, it makes a chug, chug, chug noise. between the chugs, theres a low clack type noise. i'm a little worried about this. the last time i heard this was in an engine with a knackered big end bearing. it also makes the same noise on the last couple of revs after switching the ignition off. two seperate bmw indies have said the engine fine, but not in the context of this clacking noise. my brother reckons it could be a worn engine mounting. any thoughts?
