This is fu*k up

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

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.
