It's also important to get the oil clearance on the rear main bearing as close as possible- - - -.0015" is just about perfect. Ignore that ".003 maximum" specification. A wide oil clearance lets the crankshaft bounce up and down on the seal like a sledgehammer and it also lets lots of oil spray out of the journal and overload the seal. Fortunately, a 216 or an early 235 has shim-adjusted main bearings, so the clearance can be tweaked a little.
