At first i thought it was the intake not sealing as i had ran into the problem of having to to use 2 gaskets on the sided to fill the gap when i pulled the intake off i looked for signs of sucking oil in the runners but all were clean n dry i havent changed the break in oil yet its supper thin any chance its getting by??? its not really a blue smoke like a normal oil burner not black from rich and not really like a vapor from water it stareted doing it after putting the new exhaust(with x pipe) on the car so hard to tell what bank it coming from ![](/ubbthreads/images/graemlins/shruggy.gif)

Could it just be burning the paint off the new exhaust?

One of the last Hemi's I built smoked like a mother at the dyno at start up. The dyno operator even questioned me if I installed the second ring upside down. That's how bad it was. The smoking problem came from priming the engine prior to start up without without sparkplugs. After the dyno session the car ran its best times ever.

Use compressed air to hold the valves up and replace them while the motor is in the car and the heads are still on ![](/ubbthreads/images/graemlins/wave.gif)

You dont have to pull the heads or engine... but you would need the on head valve spring compressor and a air compressor to blow the cyl up ![](/ubbthreads/images/graemlins/wave.gif)
