OK, on my current TO20 project, I ran a compression test to get a better idea of actual condition of donor engine before joining front to rear. Glad I did as # 1, #2 and #4 were right at 65# ,,,but #3 was way down at 25#,,,,aw Chit,,!! I had filled cylinders with ATF/Acetone mix while I worked on the rear main seal and trying to resolve the oil filter issue,,,,,
I've about decided to pull the pistons to check for stuck rings altho all the cylinders looked really clean,,,?
I miked the cylinder liners and get 3.010 on all of them. The book I have says std bore on a TO20 is 3 3/16". "IF", IF I do have to replace the rings,,,what size am I gonna have to order??
Thanks for all help.
