69 383 Water Pump Housing Casting Defect?
Hey guys, I’m taking the water pump off for the second time now trying to chase cavitation problems and not sure how I missed this before. Looks like theres a casting defect on the pump mating surface, and some cavitation pock marks on it. Wondering what you more experienced guys think about this, is a new housing needed or is this sort of normal? Was planning to drop a flowkooler pump in today to try and fix the problems but not sure if it will help now. Threw a picture of the original water pump in too for reference. This is a non AC car, and my pulley ratios are correct. The cavitation starts at about 4500 RPM and does not go away until the engine is turned off and back on.
