OK I did a boost leak test. So the intake pipe is NOT hook up to the intake manifold at all right I have it plug off and I have a plug on the inlet on the turbo thats were I am adding air. I tryed to put 23lbs in thats what I running for boost and there is a leak but whats fuck up is there AIR COMING OUT OF THE VALVE COVER were most people put there oil catch can hose at. Any idea on why this is happening.

Yeah, its leaking past your rings or valves... kinda normal for air to come from the valve cover actually.

Good chance its a busted PCV valve. I had a huge leak due to that with my car. Good thing to try is take a bolt and plug up the hose going to the pcv. Use a little hose clamp to make sure the bolt is secure. Pump up your system again and see. If its not the PCV you will here it leak from somewhere else. Have Fun Mine held 32PSI after i fixed the PCV till the tester kit came flying of its Kinda Scary.

Car psycho actually help'd me with the leak down test. I hope you dont have no bend valves. Best thing to do is get one two maybe even three people to help you listen, for the leak.

I had two bend valves but I got them fix at a shop in mankato two months ago.

It's normal for some air to leak past the rings and leak back out through the breather... only way to know if its too much is a leak down test though.

The only way this can happen is through a vacuum line because of the way I am doing the boost leak test. So some thing is not right with the wastegate or the BOV.

Hand held vacuum pump for BOV. . .

Umm, Why do you have it disconnected from the throttle body? Most of the time, you want it attached so you can verify that there are no leaks around the intake manifold.

This was a way I have seen people do it.
