hey guys, today I noticed that my car makes this VERY faint whistling sound with the rpm as the rpm goes above 4k. Is it a slight vacuum leak you think? If so, I guess I would have to hunt it down. Any useful ways to hunt down vacuum leaks? BTW, again it is extremely faint. And doesn't happen all the time.

The dreaded whistling sound. My car does the same thing ('94 SE-R) and I attribute it to the timing chain tensioner. I've changed mine three times but it still does it- it's been going on for over 100,000 miles so I'm not sure if anything bad will happen.

Well mine has this loud ass whistle from the front right side. Above 5k it sounds like a turbo almost. Hell I looked one time for a turbo cause it darn sounded like it. I would guess its the timing chain doing funky things.
