Turbo not spooling, but still running 6psi?wtf*UPDATE*

Hrmm, so ive been runnin 6 psi on my d16z6 del sol(greddy 15g turbo), and all of a sudden, the blow of valve sounds weak, and when im under boost i dont even hear the turbo spool? Im still reading 6psi, but all of a sudden you can't hear the turbo spool. (ive been hearing it spool/hiss for the last two years)It doesn't seem to be pulling as hard iether.

I first checked my charge pipes, BOV, and vacuum lines. Only thing i can think of is one vac line that goes to the turbo, it is blocked off . I can only get to it from underneath the car, so tomorrow morning i will check it out.

Anyone have any ideas? It really is kinda wierd...

Ok, so i just checked everything out, all vac lines/charge pipes, BOV are good. Then i noticed that im missing my idle screw. Hrmm, when did that fall out

Could that be my problem maybe? Anyway, so does anyone know the size of screw, so i could maybe pic it up from ace hardware or something, or is this something i have to get from a honda dealer?

Well, ive been noticing a very very small amount of oil on my chargepipes, and i have plans of rebuilding it in the next couple months, but i don't think thats it. What would make it so I can't hear it spool(hiss) but still be boosting 6psi?

i wish i knew what thread pitch and size screw that is... i don't know if it is why you are having the problem, but something goofy like that always plagues me

if its leaking oil in the pipes in probably needs a rebuild, sounds like the seals are going out...

Seals are going, but its not bad enough yet.. should still have a lot of life left. I just got a idle screw from a friends car, and that wasn't the problem. I have checked every damn vacum connection. The charge pipe from the intercooler to the TB is getting way hotter than it normally would, im wondering if a coupling came off the intercooler, or a chargepip barely came out, could this cause me to be running like 5psi, but not hear the turbo spool? Thats just one other thing i don't understand, i read atleast 5psi, but it doesnt pull like it use too, and i can't even hear the turbo spool?

Anyone else have any ideas? Im pretty sure its not the turbo.
