I'm having good luck using "aviation" sealant, similar to the soft stuff for most motorcycle gaskets.
Glad to see you've completed the oiling system.
Please label your lines and block adapter appropriately in direction of flow and save yourself the headache I've lost 6 months to.
Covering the conclusion for post 101
Suprastroker88's oiling issues stemmed from a split crank.
The engine siezed on hot main bearings. When the split got large enough, the sudden seizing jolt must have seperated the halves.
No bearings desintegrated, just very very worn, minimal debris in the pan.
AUX shaft had nearly 1/8" of play, trashed: this issue has been on going a long time.
And so I think someone installed a dropped and not straightened crank, forcing it down with the main bearing caps.
Or a serious tightening of the mains, front to back, left to right and not in torque sequence.
Can't think of another way to generate the characteristics of wear and seperation at the crank split.
I've got the crank on my work bench, but my camera has FTP'd. I'll put it on my build thread when I get good pics done.
