I bought this 2000 328ci about 4 months ago. Car has 98k and only 2000 miles since H ad he oil changed with BMW OEM oil and filter. Last week I stopped driving it when I noticed that the top end was very noisy, like valve train clatter. I haven't pulled the valve cover yet but from the filler hole it looks like the top side is sludged up.
Am going to pull the valve cover in the next day or so. If it is indeed sludged up, what can I do to get the top side oiling again short of disassembly? I dont have any oil light or any other indication that the engine has low oil pressure. Please post up your comments/advice
