Old BMWs, you'd have to be mad to own one
Yep. I thought only one of the hangers was knackered so bought one. I took the bumper off to do the job (much easier) and it revealed both of them gone so i'll have to order another one. The other one is still kind of in one piece but the outer one was totally ripped apart, torn, snapped, mangled, FUBAR. Stock backbox is very heavy on these so I guess it takes it's toll, they were ok 6 months ago though.
As for the smoke, never seen the car smoke before at all, hasn't done it since. Doesn't do it under heavy accel, or after a prolonged period of overrun, nor idling. Hopefully it is a one off, last night I shuffled the car around the drive 3 times only running the engine for seconds at a time. Think I flooded it a bit doing that as it stumbled into life on 5 cylinders. Will have to keep an eye on it, if the valve stem seals are giving up then that might be the straw that breaks the camels back.
