Hi,

Getting a loudish medium pitch buzz from the front of my '96 (MY 97) WRX, between 90- 100.. er on the track

Not feeling anything through the steering or chassis, prodded, poked and shook everything I can think of with no joy.

Anyone got any idea?


Also, where's the dump valve? know what they look like but can't find it! Shouldn't it be on/ near to the I/C? I/C is black with STI sticker on it so may have been changed by prev owner?

Need to find it and change to a re-circ before the wife divorces me. lol

Anyone?

 

dump valve is on the top left follow pipe from air box and its in between there and the turbo connected with two 3/4 black pipes

 

...

 

sumtimes i get the same kind buzz noise, sumtimes i dont

never tracked it down sumtimes when i get it, i can slow down then pull away again and its not there

 

guys, this buzzing is probably a loose heatshield. mine does that and is normally when enginer under load at low revs. i get them to tighten it every service and its ok for another few weeks before starting again....

 

its not my heatshield

 

Try cleaning the actuator valve, I read recently that they can stick and cause a hum. Probably a small amount of engine oil inside.Let me know the outcome please.
