In no small part due to the information and inspiration provided on this forum, I am in the process of trying my hand at my first engine rebuild (a 230 six cylinder). Looking for advice as to what should be replaced regardless of the condition of the original parts, a "might as well" approach while inside the engine. Items such as pistons (assuming the cylinders to do not need to be bored out), piston pin bushings, pistion pins, valve guides, tappets, timing chain, timing gear, valves, valve springs, oil pump, etc. Excluding the bearing inserts that will be replaced, for these other parts, if they check out OK, is it foolish to re-use any or all?
Thanks.
