I have the star stage 2 turbo kit w/ fmic and i am using the blitz supersound BOV ... well when the car starts to boost, around 3000rpm in any gear, i am getting this real funky noise ... its almost like something is flapping around or something. sometimes the turbo will spool up and sometimes it wont, and went it doesnt, this noise will start before 3000rpm ... someone said i could be leaking boost but all the couplings are tight to the intercooler and everything. someone else also said i should adjust the screw on the top of the BOV and i tightened it up some but it snowed like hell here in ohio and havent got to drive it yet since i have done that. also, the other day when driving, my oil light on the dash flickered on for a quick second and i pulled over immediately and my oil was full ... could my oil pressure switch/sending unit be bad and maybe the turbo isnt getting enough oil and thats what the sound is from? i took off the intake pipe from side of turbo and there wasnt any oil on the shaft and there was very little shaft play ... probably the same amount of play as when i got it from star. PLEASE HELP GUYS, I DONT KNOW WHAT THIS IS COMING FROM OR WHATS CAUSING IT! any suggestions or has anyone else had this noise/problem? when it does boost though, it only hits like 2-3psi. thanks guys and please help!

You probably have a boost leak.

and boost leaks dont only occur at the couplings, you may have a cracked pipe (NOT a crack pipe) somewhere, make a boost leak tester, its a cakewalk

Hey guys I have done like 10 searches for 'boost leak detector' and have found nothing ... i tried searching 2gnt and google.com ... do you guys think that if i am leaking boost that this is would make this weird flap noise ... could it be the BOV or something with the oil ? thanks for your responses and please keep helping me! i appreciate it very much! mike

edit ... 'boost leak tester' is the search i did ... PLEASE HELP ANYONE AND EVERYONE!!!

hey guys i was looking for forums to see if anyone else has had this problem as well and i read something that might be along the lines of what i am experiencing ... it said something about the wastegate might be flapping around ... maybe it isnt opening or closing or something like that ... how can i check to see if the wastegate is making this "flap" noise? the hose that goes from the side of wastegate is connected to the side of turbo and the vac port on top of wastegate is open ... what should i do?? thanks guys - mike

if i was leaking somewhere, with the car running at idle, would i be able to feel around or spray soapy water around all the i/c couplings, throttle body, vac hoses, and BOV and would i see the leak? or is not considered to be a 'boost' leak? thanks guys, please keep helping!

No, because there is no boost at idle.

will tightening/loosening the screw on the top of the blitz BOV do anything? someone said to try that but i dont wanna mess with it if you guys dont think it will do anything ... he said maybe it isnt opening/closing correctly or too late. thanks again and please keep helping me out! your answers/sugestions will help me fix this problem!

FS: 2.5" Test Pipe 25 shipped

doesnt make sense to me how he made it ... i guess you just use a bicycle pump but where do you pump into?

okay well i finally drove around the block and now it doesnt make the flap noise liek it did before, but it still isnt building boost and i cant hear the BOV anymore as i could barely before. i had tightened up the screw on the top of the blitz BOV before i drove ... do you guys think that since i tightened it up that tahts why it isnt working/boosting? maybe it isnt opening or something? thanks guys, please reply - mike
