    Well I've read all 10 pages and it sounds like you have tried several things .I will say this Garrett does generally make good turbos I've owned 2 of them and the only issues I had were self inflicted .As far as you problem rather perplexing have you tried another waste gate and are you certain everything plumbed properly ?

    Did the car jump timing?

    If it jumped timing would it show up on datalogs and flash pro? Everything is plumbed properly. It has a slight pull up till 3psi, then it just drops off. I can hear what sounds like my BOV and or WG opening. It holds the set boost level of 6psi all the way to redline. When I tested the turbo with a pressure test you can see in the YouTube video it leaks air down into my oil pan. When I close that hole. It leaks through the water cooling ports.


    I had a greddy bolt on kit previously. It ran like a champ. No problems.

    Thats not good right there. Do You still have a pcv? Sounds like it voukd have burnt a valve or something. Maybe washed the rings. For some reason the air is getting past your piston rings and thats not good. Have you put the greddy kit back on after the fact to see if your problem is still there with that kit?

    Possibly a bent valve or blown head Gasket but either way No air should be getting into your oil pan

    He actually did put the greddy kit back on and it ran just fine. So it's not the piston rings.

    Now that's nuts!

    Turbo possibly blew a seal and is letting air into the pan through it?

    That was the initial thought, he sent it to Garrett and they said it was fine. He also recently said the turbo is fine, although didn't say why he deducted that. But to me, the only major things changed from setups is the turbo and the turbo manifold. It obviously isn't a leak in the charge piping since the map sensor reads the boost, it isn't a leak in the IM or with piston rings because the greddy kit makes power just fine...

    I'm thinking it has to be related to the exhaust side of things. If the BOV was leaking, you wouldn't see the boost at the map sensor... If the intake manifold was leaking, it would leak with the greddy kit too... Are you using an exhaust manifold gasket when you install the manifold?
