i hate to say it but it sounds like one engine is hurt bad.took out a head gasket at minimum.

Right now both motors are torn down to long blocks to install new intake gaskets with the Right Stuff this time and beads around the water ports. I'll be testing again this weekend. My fingers are crossed. See pic of valley full of milky oil. Under valve covers were the same. This is on both motors. I can't believe it's a head gasket yet, doesn't seem like water got into the cylinders. On a lighter note...see pic of gauges.

I don't like the looks/sound of the milk shake at all.

I hope an oil change is on that list somewhere, lol.

Did I hear right---Both motors milked up?

I wouldn't put anything back together until this is figured out. Also, they're out of the boat, I would recommend a total teardown inspection. Lifters, oil pump, oil gallies in the block and crank,etc etc etc, are full of that stuff, A little water on hot bearings is bad. I'd disassemble the whole motor, inspect, clean everything, change main and rod bearings (insurance) double check the cam bearings, change head gaskets, pull the block plugs and blow out all the oil passages.

Sorry to hear this happened! I know you worked hard on it.

Yep, already pulled out the coffee with creamer. New oil filters are on and new oil will go in for a flush. Going to fill it with rotella to flush then new filters and back to Mobil 1 for the water test.

thanks for the kind thoughts but nope, not reversion. Ran these motors last year and all good. only thing new is this year are the blowers and intakes and carbs.

Id say it`s a simple intake leak, been there.

How much boost (psi) did the blowers make on the test run?

It would have to be in the intake crossover and on both engines. It is a "new to you" intake, and honestly, I pay little attention to the water port fit. pookie and go! Might look closer, since it happened on both, could be something odd about them.
