BOOST LEAK!!!

[Fireman40]

I have been having problems with my turbo loosing boost a high boost times. I took all the pipe and boots off cleaned them and found no cracks or holes. I took my y pip off and cleaned it and found everything good. Now that I have put it back together its like I have no boost at all. You can hear the air wooshing from somewhere. I figure I can disconect my tubes from the y pipe and plug each side of the loop. One side with a valve stem. But how can i test to see if my y pipe is leaking at the intake boots or if its leaking at turbo.

take the filter off and make a leak tester from there. You can use the valve stem to inflate the system. and find your leak that way. Ive done this many times with any car/truck i have had.

basically something like this.



but if you think its leaking around the turbo then make something to replace the filter and test from there

ok Im having a hard time telling what you have that hooked too. So your saying I can pull off were my air filter intake connects to the turbo. Then use a rubber furco capped off there to test it. My question is what keeps the air from pushing through the motor and out the exhaust.
