Need Some help
Ok i have been having some small issues since the turbo went in one that is bugging me is the amounts of oil that im loosing. I frist saw it coming out of my intake manifold gasket so i replaced the gasket but that didn't help I then replaced the PCV valve which helped for a matter 2-3 days and then it started again. No i have noticed that oil is started to go everywhere. I have noticed it started to pool up in the V of the engine, I also see some around the valve cover gasket as well. A few poeple told me that it was most likely the pcv valve and and that maybe adding an extra check valve inline will help prevent the blow by. This of course didn't work either. So any feedback would be appreciated. Ohh i also just did a compression test today and the test came out 155,155,150,145,143,145 so it is still within spec but very low for a boosted car. I have not boosted in about 2 weeks since i started noticing the oil everywhere. I am also noticing im burning oil out the exhaust too whenever i hit boost. so if anyone can give me any help that would be great

I would say you are somehow pressurizing the valve covers etc.. and it's blowing out from the seals/gaskets.
If your oil return line from the turbo is not draining well, it could be backing up into the exhaust side(and blowing oil through the exhaust system) and turbine side(blowing oil into the intake system).
You may need to install some one way check valves as you said. Are all the intake tract pipes all oily?

well i did add the one way check valve inline with the pcv valve and it helped for like 2 days and it started up again, as far as the intake runners there is oil around the seals but nothing noticable in the runners just alot of carbon buildup. any other suggestions, could be something internal that is failing?

I too had oil coming out my exhaust. Take the down pipe off your turbo and see if there is any oil in it.
One thing you did not say is,if your exhaust was smoking, thus burning oil or if it was oil coming out your exhuast.
Have you checked your oil feed and return lines at both ends?
Not an explaintion for the oil in the engine, but outside of it.
My oil feed line was leaking at the pan
