Cam/Head Swap Disaster.......

I was going to mention the oil and water will cause a big pressure increase and spiking. I would pull and check the oil pump drive to make sure it didn’t twist or round off. Whenever combatting water in a crank case, I would flush everything with diesel fuel and follow up with a flush of the cheapest motor oil accessible. If you’re going to have the intake off, I would go ahead and get some more break in lube on the cam and lifters. When adding fresh oil for the run in, get a blue bottle of STP in there, those bottom end bearings are going to need a lot of extra help. I am hoping for the best, but I am afraid the odds are stacked against you on the main and rod bearings. Babbitt and antifreeze really don’t play together too well to start with, and the loss of oil pressure out of the filter gasket is worrisome. I’ll admit that at one time, I would try flushing everything and trying my luck. But as experience teaches me more and more, I would go ahead and pull the engine and give everything a thorough cleaning and change the main and rod bearings. If the bottom end starts getting ground into shavings and going through the oil system, it is going to be a whole lot more expensive than just a set of bearings to repair. But that’s going to depend more on your initial investment and if it’s cheaper to rebuild or to come up with another engine to put in...
