Thanks for the tips.
I have done as much as I could for the oil drain back. I used epoxy to fill in the low places next to the cam. Then I painted the inside of the block. As for the dis assembly, I only got as far as pulling the top end apart then ran out of time. I work 12 hour days so time for the car is limited to the weekends. I will be back out in the shop in a couple of days.
