I have a '98 Subaru Legacy AWD with 100k miles. When you rev, it's louder than it seems it should be and the usual engine noise sound is accompanied by another gurgling noise. It sounds kind of like a low-pitched bicycle chain click and is constant. My girlfriend calls it the Jetsons car now. Weird, no?
Also, if I accelerate uphill I can make a metallic rattle like a lid on a pot vibrating. This occurs briefly.
Pretty neat, huh? Any guesses? Any questions?
THANKS
