A word of thanks to everyone that has helped, advised, did my thinking for me, text, called, posted, and joked. You know "How many Hillbilly's does it take to ..............". Thanks for helping me along and being a part of the team.

I really enjoy the tear down part of the engine it give me a new list of how and why this or that happened. Got to go Dumbo is calling

Since I'm the engine builder I will have to take the blame. A air leak, @ 45 psi, was found at block to front cover. Water flows both directions to and from water pump through front cover. Will check block and cover for flatness, O ring grove for depth and finish, and O ring type gasket for cuts. Reassemble and re check.

Checking tool was a blocked off water pump, 0-60 psi tire gauge, Schrader valve. Gauge was piped in.

Good job finding that leak! Better than a crack somewhere.

Leaking in chain area

I would think that at 45 psi you could create leaks that normally would not exist. Check the oil drain back hole near the block water drain plugs. That is where the aluminum blocks have been known to leak water.

Maybe try using antifreeze vs water for testing. That stuff will find its way out of places water won’t.
