Engine building questions?????

Rotella won't work for the flat cams anymore either....it has the package reduced now to meet the '07 diesel truck emissions.....your gonna have to run a "race" type oil that doesn't have to pass EPA emission standards. As for the cylinders rusting...go to your local NAPA and get a can of fogging oil......it is used for storing engines over the winter....pull the plugs spray some in the cylinder and put the plug back in.
