Hi Bigtim,
I would love to learn how you made the bearing puller.
Another thing that I noticed in cleaning the engine was that the cam followers were sticky in their housings. Likewise I used a sonic cleaner with soft bristles to clean them. I have never used 3 in 1 oil as I do not know its make up. I know Dave in his videos uses them. In putting the engine back together, I just used after run oil.
