Hi everyone.

I own a stock TURBO II that a couple of days ago started to smoke bluish, and smells like burned oil, like Mitsubishi Mirage does. Somebody told me that a broke turbine or a worn housing gasket may produce smoking. Curiously, is smokes at idle speed, but not at 3,000 and up RPM. I'll be grateful to hear opinions.

 

could be the pcv system, but kinda sounds like the turbo

 

First things first, if you are premix try stopping and see if it goes away. Then vent your crankcase to atmosphere. It should be vented that way regardless. Then check your intake tract and turbo inlet duct to see if they are full of oil. If they are dripping its probably the turbo. Clean them up and recheck after you vent your crankcase. If there is oil again chances are its your turbo. Check your spark plugs to see if they are full of oil too. Generally pulling the turbo off will let you know if its the turbo...



I'm also assuming you are using the stock hardlines for the oil feed and return..
