I'm experiencing some high crankcase pressure when in boost, to the point where I have oil coming from the dipstick (seal on that is worn out so I can maybe fix that) and also also shooting like a jet out of the timing cover to cylinder head junction. The timing chain to cylinder head junction is due to the head gasket having torn there. Now I'm not 100% as I haven't been able to look at the leak under boost, but the aftermath is oil getting all the way to the firewall and shock towers with oil puddles at that gasket junction, so I'm suspecting there is some high pressure involved.
My current PCV is the factory block tube to manifold, PCV valve seems to work fine from the me blowing in it test, and then a valve cover breather. I see people recommending instead of the breather going to the air filter, but I just have a cone filter directly on the turbo, and not sure how I would achieve that.
Is there any other advice how to remedy this? I really really don't want to pull the head to replace that gasket, and it does not leak at all while not under boost (plus this would just make the next weakest link leak. I'm surprised that the pressure isn't relieved by the valve cover breather honestly.
Compression is showing pretty good 165 on 5 cylinders 175 on another, but no idea on what the mileage on this motor is.
