I have not yet torn the engine apart, but it blew through the vc gasket, I'm sure the valve seals, and I'm not sure if it did in the head gasket...
I cant see how it could build up this oil presure in the head where it could blow out VC gasket and Valve seals.
If there is a breather on the valve cover going between the MAF and turbo or open to atmosphere. There is no way it could blow out the Valve cover gasket seal. No one would seal off the valve cover so this is out of the question.
The valve sealas are under no oil presure, on a turbo car they can catch a little boost presure from blow by through the valves when under boost in the intake.
One of the main problems that alot of people have is their lack of knowledge on what they are doing. I have seen many small things that have driven people nuts. most common below.
1. running rich - bad gas mileage. Someone puts on a large 255 Walbro pump and dont realise the fuel presure will go up into the 55 PSI range at idle from stock 36 PSI. This is generally a 1/5 increase in fuel delivery. Yes an adjustable FPR needs to be put on but they dont know.
