Just a quick update - MoCo gave the OK to open the engine and see what’s what...near as we can tell, I had an early model pump and even though it wasn’t sumping there was inadequate oiling. Valvetrain was shot...rocker shafts, bushings, vam, lifters - all hosed. Minor scoring on the cylinders and pistons.
So they’re basically rebuilding the entire mill except for the cases and crank. Everything spec’d good on the bottom end so we’re not going with a new motor...this time. To be honest, I’m not 100% sure this will be a one-and-done fix.
Should have it back soon, all of the parts are in. Stopped by today and they had the cam chest buttoned up, new jugs mounted, heads on, just waiting for the rocker boxes, pushrods, etc. and then bolt everything else back on. And of course, rain in the forecast for the next 8-10 days.
Let’s see if this one will hold together for more than 3,000 miles...
