So I've been losing sleep at night trying to figure out why the vw won't spool the hx35. It will start to spool, and then just kinda fall flat and maintain that pressure. I pressurized the sytem to 30+ psi and couldn't find any leaks anywhere.
Then I started wondering what would cause the valve cover to literally BLOW oil all over the bottom of the hood, and why it only does it when driving. I can rev it up in neutral and it doesn't seep oil at all.
Then I remembered how the holset was leaking oil out of the exhaust and compressor side, and I fixed it with a bilge pump.
So I'm thinking that the turbo is leaking boost internally into the oil passage, and the extra air pressure leaking into the oiling system and block is causing the valve cover seal to fail, and spew oil everywhere.
Is this possible? It's losing about a quart or so every 400 miles. I'm really hoping this is the cause so that I can fix it when I switch out for the garrett. Since I just now thought about it, tomorrow I'm going to pressurize the system again, and take off the oil fill cap and feel for air pressure.
