I haven't talked to the engine builder for some time but I visited him yesterday so I can give everyone an update.
First off, I would like to thank George Anderson for his input since a pressure test on the intake hadn't been considered until George made the suggestion. Plates were made and the intake was pressurized. Immediately 3 pushrod tubes began to leak with very little pressure applied. All of the leaks were at tubes that had been sleeved by Dove.
Since this intake had been used on the original cast iron engine with no problem, it is being assumed that the heat applied during the powder coating caused the sleeves to develop the leaks. In any event, the intake appears to be the cause of this
oil consumption problem.
Thanks again,
Wayne
