When i sometimes hit vtec i see blue smoke comming from the exhaust. I know blue smoke is oil. The problem is i don't know where it;s comming from. I did a leakdown test on the engine and it's at 4%. I also did a compressing test and it's in between 150 to 160 across. I inspected the plugs and it's clean and burning normal. I inspected the 02 sensor and also no sign of oil. There are no oil leaks. So where could the oil be comming from? Some people said it's the oil control rings. If it's the rings shouln't i see oil from the plugs? Only burns oil at high rpms at wot.
