Where do both of these lines connect to?

Can you remove the check valve on the blue line and make sure it only blows out and not back in?

The pcv goes to intake like stock and the other one goes to atmosphere

Goes to atmosphere? It doesn't connect to anywhere on inlet to the turbo?

 

[TasosEclipse]

No

 

[Anfurnyy]

No

Okay and what about the other line with the check valve? You'll have to take it off and blow through it from the valve cover side and it should go through. Then blow through the other side and make sure it DOESNT go through. It's only meant to let vent crankcase pressure into the intake manifold but keep boost pressure from pressurizing the crank case.

I checked the valve it moves like you said

I mentioned this before, but make 100% certain the turbo oil drain is not obstructed.

 

[TasosEclipse]

I checked the drain and double checked it and I have 1mm restrictor the turbo is perfect.

 

[dwb]

What? You have a restrictor in the drain???

 

[TasosEclipse]

No in the pressure for the turbo because is ball bearing.

Okay so if your check valve is fine and your other line doesn't go anywhere.. the only sources of oil to your intercooler pipes would be your turbo.

Your turbo only get oil on the feed and return.. so either you have a bad turbo, (which sounds unlikely since you said it was replaced) or your oil drain is backing up because of overfilled oil, you're overrunning your turbo with oil pressure causing it to leak out a front seal of some sort or crankcase pressure. Those are really the only 2 possible options given all the process of elimination we just did.

Show us your oil drain please

And your oil level on your dipstick

 

[TasosEclipse]

Now the oil is down to 700ml

That line looks kinked or isn't downhill.

It looks like it's got a low spot lower than the oil pan port.

 

[TasosEclipse]

I use the stock return line on the pan

Well that's fine if that works but it looks kinked or like it goes below the oil pan drain hole, and then comes back up. Oil won't drain properly if it's that way. The oil in the drain is mostly gravity drained so if it's not a good ALL DOWNHILL drain you're probably going to have drain issues.

Red line is the oil drain. See on the left it goes BELOW the port on the oil pan? That's bad.

Its like the good one it’s going like the bad one

I think we need a better picture of the drain line to see for sure.

Plus a 14an is pretty large and that's a fairly tight bend. I would be surprised if you made that line fit without a kink in it.

Can you get us a better picture of the drain line?

 

[TasosEclipse]

I could take one tomorrow

 

[TasosEclipse]

Here is the return line

You see it right? Your return line dips below the level of your oil pan flange aka the "bad" setup. Oil pools in the line and causes enough back pressure to start pushing oil out the bearings instead of free flowing into the pan.

It might be difficult for that 14an line to be shortened enough without kinking. You might consider a kit like this instead, and make sure you shorten the line properly to eliminate any low spots like you have now.

I'd say this is almost 100% likely your problem
