I have a 94 integra with a b18b1 block and a jdm b16 head. the motor is all stock with the b16 cams. The motor pulls hard in vtec, but sometimes (not all the time), it will blow out smoke really bad from the exhaust. I just did an oil change with 5W30 half synthetic motor oil. When it smokes, a TON comes out and then stops when I come to a stop. Obviously its burning oil, but what can I do besides Piston Rings to stop or slow the proccess? I beleive it has the LS oil/water pump gears on it. Its running on a p28 mugen chipped ecu. Also when the motor is cold from sitting all night, I go to start it and it idles very low, lower than the stock idle. Then when it gets warm it idles at like 8-900 rpm. When driving, sometimes it will idle at 1100 rpm. Any clue why? No check engine lights ...
