Groundhopping

Got 3 engines to test.

Think I might hook a radiator up and run enough to get up to temp and make sure the booster pump isn’t making oil. Check Water pump for leaks. Replace oil lines on bottom of IP while it’s out. Delete intake heater supply. Check oil pressure…what else?

@DavidWymore that sounds good (especially doing the IP oil lines while the engine is out). Maybe steaming the engines down and then check for leaks while you run them. Practically anything is easier to fix while they are out. Exhaust manifold gasket leaks, rear of the head oil leak etc.
Main seal?
Wow, with three engines to ground hop it makes sense setting up a frame and rad and just swapping engine after engine. Fun! Ground hops are great! Nothing like a roaring multi without any muffler!

This one might make a good test bed with the tilt front end

Really ought to check for good rod bolts…
