Not an option...Hey Onur, are you able to revert to NA for the time being?
When I did my home brew turbo, I thought of that, although I do have a flipped over exhaust manifold which would make it easy. I even kept the stock exhaust down pipe.
Not sure what else to suggest bud.
Is there oil etc coming out the rocker cover vent? If the crankcase is pressurized that much, surely there would be excessive pressure out here too
It must be coming from the turbo tho, because looking at the earlier pic of the exhaust manifold, it's dry so it can't be coming 'through' the engine as suchOil out the exhaust means it is making its way into the cylinders. You had that sucker rebuilt, so it can only enter via intake. That may mean that indeed your crank case is overpressurizing as I assume you have routed your valve cover breather into the intake preturbo. I blew my rear main due to overpressure before adding a catch can. The hose I had rerouted from the valve cover to the intake kinked under heat, so was easy to spot problem.
