I was leaking oil a couple days ago. I replaced the oil pan gasket, oil filter flange gasket, oil cooler o ring and Oil pressure sensor. I thought i had fixed the leak so i was driving and i hear a loud "pop" sound. Then white smoke was coming out of the exhaust. There was also smoke coming from the exhaust manifold. After i pulled over and let it cool down it was okay. i was of course going easy on the throttle just so i could get it home. Then i changed the coolant and ran it again. It did it again once i got past around 5k rpm's. Same exact thing. The car wasn't overheating either and there's no water on the dipstick. Sound like a headgasket?
