from the threads i came up with while searching, it seemed like oil was somehow the problem? i never found a really clear question & answer though.
i get a knocking sound from the frontend of my car...sounds like it's from the engine. but it doesn't sound like metal on metal...and it's not really harsh at all. the times i hear it are when i'm accelerating, usually been 2000 and 4000 rpms....typically in 2nd and 3rd gear. i've heard it a few times in first...but it's rare.
the sound started about a week ago. (i've never had it before)
happens when it's warm and cold.
it speeds up as the rpms go up/i go faster.
it doesn't happen when i'm not in gear. (it just purrs like it usually does)
and it doesn't happen when i'm maintaining a constant speed/rpm.
last time i changed my oil was about 3000 miles ago. (i want to do it now, but i just don't have the time or means at all)
