Ok i have did some reading but jus need a lil more help to pin point the problem for a friend.
he has a built 84mm gsr turbo. and just recently his car began to smoke a blue/white smoke and u can smell the smell of burning oil. so when he start his car up in the morning it smokes some but once he drives it partial throttle it goes away until he decels, then u see the smoke again, once he is sitting at a light a cloud of smoke comes from the exhaust. so w i told him to get on it to see if it smokes and it blows a small puff of smoke then it doesnt smoke while he is in boost. can someone help me pin point this.
