This is fu*k up

[travail]

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.
Here are some pics

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.

Oh, perhaps that explains. You should pressurize your whole intake system as well. You can either start from your throttle body. Or from your turbo outlet. You'll get it just be thorough

I have never done a boost leak test before. So what the best way to do it?

Seems like air is leaking passed your bov and going through the line to the intake manifold, then through the pcv line, and then through the breather. Hook you UICP back up to the manifold so you can pressurize the whole intake system.

Just hook your UICP back up to the throttle body. That's the normal way of doing it.

Thanks will do. But wont some of the value be open and let air out through the exhausts manifold.

Valve i am assuming. No they should be sealed unless you bend them again. Did you figure out what caused the valves to bend the 1st time? perhaps the problem is occurring again. Gives a little more detail as to what goes on under boost. Does your car sputter or do you just hear a leak? Does it idle like crap? Or does it just not want to go above a certain RPM?

To make along story short. My timing belt tensioner was bad and I didn't know that. I was having some fun and the timing jumped and I bent two intake valves. So I had two new ones put in but I doubt think that place that did the work did the three angle valve job on them to mach the other ones. Me and shane at DB were thinking that there might still be some bent valves or a bad valves guide. Because there was some oil on the number one cylinder and the other three cylinder look good.

The car run's way better then what it did. It put down 330 to the wheels. Shane was telling me that it STILL A 130 to 150 hp off of what it should be with my set up. It just stop making power even with more boost so that's why we think it the head. I did a compression and leak down tests and it was all good. So now I am thinking it a boost leak.

Go off the turbo for the boost leak test

[mlomker]

Your threads have been interesting...I've never had to do these test before, either.

It sounds like the shop you went to in mankato just did a quick fix at your expense. If there are valves with an angle job and then they throw in just a normal valve they are doing it wrong. Im guessing that they just repaired it and that they didnt pull out all of your other valves and check them for minor imperfections and the guides for issues. Im guessing there is still some damage in your head. I would pull it off at some point and send it in to a nice DSM specific shop to get it checked out and reworked over.
