Time for an update.
It appears we have found the smoking gun regarding the persistent oil consumption. Karl sent the heads to a different shop to get looked over, cleaned up and to install the new Manley valve springs I picked up. The consensus is that the valve seals installed in the first rebuild had come loose and were riding the valve, effectively PUMPING oil into the cylinders. The rings may have been fine. Even though the oil consumption symptoms were very similar, it's tough to say if this was an issue with the original build. The heads were gone through on the first rebuild and nothing was mentioned as being out of the ordinary (besides tell tale signs of valve float).
So here is where things stand:
- New Diamond custom forged pistons ordered, 2618 material, double diamond coating, H13 pin, machined ring area after coating. These should arrive the first week of November.
- New Callies 5.85" forged rods
- New Total Seal conventional style rings in hand
- New Crower link bar lifters
- Block work is done. Just needed a hone.
- New King bearings will be installed all around.
- Heads have new Manley springs setup to avoid any future valve float
