fucking turbo
 

ok, i got the turbo on, blah blah blah. theres a problem. when i rev the motor the turbo spools fine, but when i let off the gas, the turbine slows, but it makes a chattering noise. i was like what the ----? so i drove it and it pulls hard but still makes that noise. so what do you think it is? i have a slight oil leak but i think its because of my drain line being a litle kinked. HELP ME!!!! the car needs to be better ny sunday!!!!!!
edit" its not like a twist, its like when you bend a hose and it bind a little bit in the middle. help me out here guys

sounds like youve got compressor surge! do you have a blow off valve?

i have a bov, its the fog horn style. should i try spraying the cylinder with some wd40, maybe its a little jacked up. i have 30 vac when its idling, but im running the boost gauge and the bov off of the brake booster

Re: fucking turbo
 

i dont think your BOV is working properly... try lubing it or something. i have my boost gauge and bov both t'd off my brake booster also, no probs

Re: fucking turbo
 

your bov should be open at idle, is it?

Re: fucking turbo
 

it turned out to not be the bov that was making the fucked up noise. the wastegate flap was spining arounf inside of the turbo. all i had to do was put a washer on the internal wastegate to make it sit higher up on the flange and now it purs like a kitten.
