Greddy type s broken?

[98gst62]

Just before full boost and during full boost the bov flutters and i lose about 3-4psi after spiking. it wont hold (at 15psi). I have tried tightening it down but that does no good it still leaks. Is the spring bad?

Do you have your vacuum line hooked up to it right? Is the bottom nipple unhooked and not capped? We need more info and possibly a picture.

I saw an EVO with a broken greddy bov at TOPSpeed in atlanta on the dyno

the diaphragm (sp?) gave out and anything over 10 psi it would open at wot which resulted in rapid-fire-fuel-cut and alot of black smoke

maybe try another bov?

The top nipple is hooked up to a vaccum line and the bottom one is just open. It just recently started doing this. I just replaced it with the type rs to see if that helped and that one does the same thing! I dont know, could a vaccum leak cause it?

The top one should be tee'd off the line going from the compressor to the wastegate or something to that affect. Go through all your lines.

After I installed the type rs, I searched tons of threads on how to adjust it and followed them. the bov still flutters in third gear at about 1/2 throttle then at full throttle it doesnt. it makes a clean sound at low boost when I let go of the throttle but high boost it flutters. I have had the screw almost as tight it will go and as loose as it will go and every setting in between to no prevail! I dont know what to to??
