Rebuilt engine leaking oil
Answer
question did you rebuild the motor, a local shop rebuild it or was it pulled and taken to a machine shop and they rebuilt it? We will go fom there. Note why was it rebuilt as the motor is a beast!!
The engine was rebuilt because it was doing the same thing. Burning oil and fouling the plug to the point of misfiring. I pulled the engine and and took it to a machine shop. They did all the machine work and put new pistons on the rods. I took all the parts back home and assembled it myself and re-installed it.
The blue smoke and smell sounds like the valve guides are severely worn. New valve guide seals won't do the trick, even if they are the positive contact type. If umbrella type seals were installed, then you could have oil leaking down into the intake runners.
Generally rings that haven't seated won't cause blue smoke at startup. But during hard acceleration...!
