Lowell, how much oil and where?Originally Posted by Gene in NC
My tech says that my very noisy top end problem that developed immediately following
oil change may be from the m30 oil pump failure of an aluminum shuttle valve
sticking and if so bottom end may be fried as well. Ever heard of that?
My '68 '02 had unbushed aluminum rockers wearing out shafts and rockers in about 40k. BMW mechanical engineers seem to learn very slowly, if at all. Why the hell would they ever use an aluminum shuttle valve in an oil pump?
Just one more worry. If my "info" is true, might be worthwhile to check out oil pump.
