problem with the sr...

when i let the car run for a while, or 2 minutes, it builds up extra pressure in the head. when i turn the car off the air is being relased where the dipstick goes in. i was told to check the pcv valve, which flows fine, alon witht eh other hose that runs into the valve cover. both of these flow freely, so i dont think the problem lies there. i was just curious if anyone else has had a similar problem and what was done to correct it. if he car is driven under boost for a while, the dipstick will actually shoot out, and oil splatters all over the place. let me know if more info is needed, and any input is appreciated. thanks, chris

Did you plumb your idle air feed after the turbo? It is supposed to be pre-turbo.

the hose that goes from the turbo, to the black box(looks like a pcv vale maybe) then goes to the t on the manifold. the other end of the t is capped off. where should the other end be routed to. could you please show me a picture possibly of what you are describing. thanks, chris

just vent it (the T on the turbo side of the head) That NEEDS to be open, if you plugged it you need to undo that ASAP. That extra crank case pressure is not good for your motor (wears the rings out, lets blowby get into the oil eating up your bearings ect).
