hum/vibration
this has been going on since i put the car back on the road in the spring. Ive been neglecting to post about it becasue its kind of hard to explain. Hopefully i can describe it good enough so you guys can give me some suggestions.
Its a hum or a vibration coming from/near the passenger front. It sounds almost like my tire is rubbing something, but i checked my clearences and its no where near. So rule out tire rub. (even though i did put on the new wheels and tires)
It happens sometimes when im hard on the throttle, around 3-4k revs.
It happens sometimes when im letting off the throttle just barely (like when my bypass valve would just start to open).
Sometimes it doesnt happen.
Would the bypass valve cause such a sound if something is wrong? I cant be positive of the area its coming from because i cant listen under the hood while driving, and it doesnt happen in neutral (cant get the BPV to open in neutral anyway). The BPV sounds like its working normally. I hear the turbos spool as i rev, then at shift i hear the "PSSHHhhhhh...".
To try and more acurately describe the sound, imagive a board being run over a table saw. Its that sort of patten of sound, only not as high pitched or sharp. Like dragging a wrench on the tread of a tire spinning fast. Lasts for about 3 seconds (unless i let off the gas, then it stops quicker)
well thats really the best i can describe it. any questions ask away. thanks for any info you guys.
