Thanks for the reply. If it was not smoking, that would more then likely rule out the turbo or a cylinder. Only other things i have seen that caused this, is to much oil in the system and i have seen the constant throttle valves (ctv)cause this also. I hope this helps you out. I would definatly recommend getting the crankcase pressure tested. If you have anymore questions, just ask.
