HEy,

WHen i accelerate and begin to boost, almost immediately upon boosting, i can hear a wooshing sound. It sounds like the stock B.O.V.'s are opened. Then, when i let go of the gas i hear the same woosh, Just louder (cause the b.o.v.'s are opening i guess). I have a boost gauge and i am not exactly sure but it think its telling me i am only getting 4-5 psi. I will do a boost test tomorrowe and post my results. SO what do you all think? Boost leak? If so where may it be and how do i go about finding it? THanks alot. Is there a difference between boost leaks and vacuum leaks? Just wondering. Thanks for all your help!

I posted this to another member.
I've found that the best way to find boost leaks is to take some soda cans or tennis ***** or anything of the like, and put them in the intake hoses(from the airbox to the turbos). Clamp the hoses tightly around the cans. Next, get a blower nozzle for an air compressor that can have a vacuum hose slip on. Put the vacuum hose on the blower nozzle at one end and an intake nipple at the other end. Tighten the vacuum hose down with hose clamps at both ends. Turn the car on(not the engine though). Now lightly blow air into the intake with the blower. The air will have no where to go except where the leak is.
Hope it helps.

 

which hoses should i check? all the vac. hoses till i find it? or is there any particular order? thanks
