My Cat rod bearings...

[Zhidden]

The tops definitely show the coolant. Antifreeze breaks the film strength of the oil and the top bearing takes most of the flak...with that said however I am seeing a lot of contamination in the bearings and #1 definitely had something behind the bearing when it got installed. Clean, organize the parts, clean again, get everything ready and clean again. You can never be too clean working inside an engine.

Here are a few out of a SDP with 600k on it. Bypass valve stuck in the pump and they ran it for 500 miles with 15psi oil pressure - shut down 59 times due to pressure. You can see on one bearing a spek of something was behind it during install. It does not take much to throw them off and do bad things.
