I recently built a 4.0 Renix non-H.O. head on a 4.2 block.
what it's doing is when it's cold it doesn't smoke,but give it some gas and let it warm up and it lets out smoke.
I'm not losing oil or coolant and the smoke smelles strongly of gas.
it's a straight up head swap but I blocked off the EGR
4.0/4.2 over-fueling need help
