Hi Eric,

Machine shop says bores / pistons are ok. Big ends on con rods must be bored and rod journals on crank ground. Micro-polish on mains only. We will use the Hastings rings you recommend.

The shop has drilled additional return holes in pistons. However, I offered to get additional info if I could from you. If you have a summary of the process that would make me feel more comfortable. There are two holes on each side currently and you can see a boss in the casting where the holes go through to the center of the piston.

I did call Toyota and they did not indicate there was an updated ring set. They definitely had updated pistons so I am assuming the oil relief is better in these.

Many thanks again.
