Hi there!
I've done some searching and not found anything that exactly matches my problem, hence my post.
:1zhelp:
After a mild outing (it was quite wet!) on my first track day in my E39 last month, I noticed a noise coming from the left hand side front of the car when turning in to right hand corners. When I came in, I checked the front of the car / engine and couldnt see anything obvious.
Mentioned this to my friendly main dealer service manager and he thought that it might be the wheel bearing or power steering pump starting to go. So, they tested it and said no, bearing and pump all OK, BUT they had noticed some noise coming from the engine. So, stethoscope out / remove belts and they say noise coming from the oil pump region... (starting to get worried now).
So, they dropped the oil pump sump (didnt know there was a separate sump?) and visually checked the pump (i.e. didnt strip it down) and I was informed its OK. They then removed the oil filter / checked oil and apparently there are very fine bits of metal suspended
confused: as to how they know its metal) in the oil and caught in the filter... :crying:
They are a bit unceratin as to the cause and have contacted BMW Central for some advice, which I'm still waiting to hear. I've not seen the oil / filter yet (I hope to go to them today)
Now, the only thing that I think could be relevant was that I had the oil / oil filter changed about 2-3 months ago (same dealer) and when I picked up the car, the engine was "tappety" and I said "thats not right" and they took it in and said "air lock" and it came back about 25 mins later running as before. So, did the "air lock" damage the engine???
So, after looking at a load of threads that make me want to weep, I've realised that it could be any of the following - rod bearings / oil pump / vanos / cyliners scored / camshaft wear / contact between timing chains and housing - I thought I would post here and see what the consensus is.
Car is 2001, UK origin and totally stock. Any thoughts/suggestions would be very much appreciated.
Thanks
Nick
