dosent sound right to me.

i was think some thing along those line to it must damage some thing somewhere,fist port of call to me would be the turbo.

wait till i see him later,he's a bmw mechanic,and he's bang into honda's,they dont have turbo's. i'm gonna tell him he knows nout

i'm still gonna slap him for talkin out of his back end,lol.

I have to admit I do love that "wooosh, tisssh" noise...cant get it on a diesel though without alot of money been spent for little effect due to low pressure for the turbo on diesels.

........can these recirculating valves pack up or not work?.........if they do what happens or what do you hear?.......the reason i ask is that i removed the foam from my airbox thinking of a more smoother airflow and yes i could then hear a noise.....but to me it sounds like the turbo is turning with dry bearings, but only when i lift the throttle.......normal running and at WOT no noise at all!!.......the vacuum pipe to it is fine.....
