what kind of oil for new rebuild

The people who know will be the ones who have engines that run for 200k, 250k or 300k + miles; they can show the others the info, but they cannot make them believe.

The ones who "THINK" they know all the answers will just blow lots of smoke and post poorly spelled and poorly thought out proclamations of intelligence on the bulletin board, and will be replacing/repairing their engines more frequently than the rest of us, whom are intelligent, keep informed, up to date and open minded.

Personally I keep the engine work to a minimum, so's to spend more time driving.
