ok ive got a t3t4 turbo ,peak boost manifold ,tial wg .6 bar , knock off type rs bov , a pcv valve from a car i thought you work . im going to make a plate for bov tomorrow and drive it .then do boost leak test but man it drives me nuts hitting 7 psi and bleeding back to 3 to red line . any help could a cheap air filter cause this . Any ides would help and i got a thermal intake gasket .

 

i would check at the BOV first..... if that doesnt seal.. you will have issues no doubt... i know i did. if you google *Boost leak tester* you can find out how to make one... you must find the leak with the car off.

 

^x2

 

Im making a bov block off plate today well hre in couple hours after i wake up . and ill go test drive it I pray it fixes my problem .Thanks guys .

 

Well one bolt on my compressor housing is stripped out , one is started so its at the machine shop getting heli coils put . Will have it back tomorrow , but it had major leak right off compressor housing .

 

hmmm lets us know.

 

well fixed most of leaks what pcv valve can i use for a for my notch top . zenki . cause the s13's wont work. any cross referenced i can use that wonk leak under boost ??

 

hmmm i have no idea.. but tomei has a good OE replacement with a stronger diaphragm and spring.

 

well the one i used leak a little bit and the pcv valve grommet was torn went and got one that match it size and was for a ford . lol but i did some searching after i found the housing was stil leaking and i don't have a seal between the compressor housing and the back plat and was (or might still be ) leaking . dsm forums had a huge 3 page post about it i still made need an o ring they apparently have had problems with 50 trims on there dsm leaking and not having an o ring i used copper gasket maker ,as they had instructed . one used a small bead around the edge of the backing plate and let it cure (i wish i would have read through all the pages first )but i need to do another boost leak test and see what is going on . But my iacv screw o ring is leaking and the main part below it , so for now i drimeled off the plastic crap it had on it and used magna steel on it . so i will see some time this next wek if my problems ar fixed but i think they waste gate is opening to early i here a flutter sound when i hit 5 psi and i have the bov blocked off completely . hopefully this thread will help some one else going through the problems i have cause ive been trying to fix this for about a month now .
