Well like the title said i removed the hose from the pcv that goes into the intake, to check for oil possibly going into the intake from it. Air came out of it while the car was idling (and smoking lots) but no oil. not even a trace. maybe this could be one step closer to ruling out cylinder ring blowby. thought? ideas. btw i still havent had a chance to do a leak down, i really need to i guess. what percent should the cylinders be at?
