Moving along in an engine refresh for my FJ40. Original cam and lifters. 5/6 original pistons. One piston replaced due to damage by rings. All new piston rings. Cylinder head disassembled, cleaned and reassembled. Will do initial valve adjustment and set initial timing per FSM. Cylinders will be honed. Rings will be checked for correct gaps.
I've read about the oil and the zinc additives and multiple oil changes. Does any of this change due to piston rings and rod bearings being the only changes? Is the only main concern getting it fired, getting the RPMs up and running for 20 minutes or so to seat the rings? One oil change after that...more?
