Someone please correct me if I'm wrong but the issue that is the subject of this string is for N52 engines only. It does not pertain to M54 engines, which is what a 2001 330i would have. If your M54 engine has this problem, it is likely from a different cause.

All dealerships I've spoken with tell me its a common problem that will in no way effect the longevity or performance of the engine. Basically just deal with it. I hate the noise though!! It sounds petty but it really ruins the driving expereince of the car. Finally I found something that works! This past weedkend I changed my oil. I used casteroil 10w-30 for one (slightly thinner so easier to pump up to the lifters). I also used a quart of Lucas Oil Treatment. After the change I started the car, made sure no lights were on, no leaks, correct oil level ect. The ticking was still there so I reved the engine slowly up to 4k rpms and held it there for about 30 seconds. This just pump oil up the lifter tubes. TICKING GONE!!!!! Pardon my french but, Lucas is the s**t!!
(note) It is recomended to remove a quart of oil and replace it with 1 quart of the Lucas oil treatment. I however did not. I run my engines about a quart high so my mixture is 7 quarts cateroil, and 1 quart Lucas oil treatment. This has never given me any trouble.
