White smoke from exhaust smells like oil
Hello I picked up a really clean 04 monte ss the problem I’m having is the guy said the car runs like crap and well it did I found out there was a problem with the number 1 injector being stuck open it ended up being a short in the wire harness so I fixed it the car runs great now but there is allot of white smoke coming from the exhaust the oil definitely had fuel mixed in it I’m assuming it’s from the injector being open so I changed the oil it’s smoking but not as bad as it was at first it smelt like pure fuel out the exhaust now it smells like oil the but the smoke is white the temperature is normal the antifreeze is good not low or sludgy the car definitely doesn’t feel like it’s lost power from bad rings of anything to be honest it feels like it has more power then a stock supercharged monte the smoke seems to clear while driving until I’m at idle or if I give it a rev any suggestions maybe bad valve seals I’m not sure i also checked the pcv valve

Sounds like you got a handle on this, I would also guess valve stem seals. Does it seem to smoke more on start up which might indicate the seals are leaking ?

As your already aware that it could be the rings leaking oil, not sure if that would cause a running issue until you had enough oil fouling out plug. Have you inspected the spark plug to see if there's oil getting on it ? A compression test might indicate bad rings or you could pull plug and pressurize cylinder with air a see if it has pressure in the valve cover that would indicate bad rings. Not much you could do to solve a ring problem except rebuild. Good luck
