Wow those water passages remind me of the way the Titanic looks. Crusty crusty crusty. Having the block & head hot tanked will take care of it. Couldn't you change out the oil pump to a slot drive & save a headache? Or maybe I'm missing something.
I have to say again.........love the work and thanks for sharing your work. I wish I was closer so I could get some close up and personal insights to your work. Stay well and keep up the great work!
Well, my oil pressure cheat worked a treat! (I forgot I was going to video it - oh well)
It went exactly like I thought - at first the drill didn't want to turn the cam as all the valves are in place so I rotated it with a wrench to an "easy" place, then the drill spun it like mad! I felt the pressure come up quickly, I doubt it took even 15 seconds on the drill before I felt it and heard the drill slow way down. I did that one more time - checked the dipstick and it was a quart and a half down, topped it off and went again but only for about 10 seconds.
I didn't have any gushers but some oil did find it's way out from around the front main bearing and cam bearing - another sure sign that I have pressure, and there was oil in the top gallery too.
Now when I go to start it I know it will have immediate oil pressure just as if it had already been running. I'm just waiting on a few more bits so I can button it up and put it in the stand and fire it up. Stay tuned!
As I recall the early automatic transmissions for the A series engines were problematic, but there were rebuild kits that fixed many of the faults. It has been many years since I worked on A series engines, but I seem to remember that if the auto transmission was painted the engine color it wasn't updated and if it was aluminum color it was.
Good luck on the surgery. I had a friend that had it done. He was very happy. Before he got it done he could no longer kick over his old Indian. After the surgery he was good as new.
