I have a 1994 525i. I just had the water pump and fan clutch done and
while it was in the shop they asked me if I had been hearing the noise
from the front of the engine. They showed me on my car where the noise
was coming from and it seemed to do it at higher and lower rpms, but
more noticeable at lower rpms. He said it could be just a little
piece of metal in there that shaved off and that after you take that
out it could be fine. But, if it does more damage or if the chain is
loose, i could wind up wrecking the engine. I looked at trying to
take the cover off of it, but it appears that you have to take the
whole cover off of the whole engine compartment there which has all
the spark plugs and everything. If I remove all those bolts, is there
oil in there that is going to come out? And, is something that I even
want to open up and check into?
Appreciate any help.
