GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
When I had water in the oil and 2 cyls from a blown head gaskets I changed the oil and filter 4x. Try running it on the water and changing it after it gets nice and warm. On the water hose the oil will just not get that hot. Then see what happens to it. Since I fixed mine I don't see any milkyness either on the stick or on the oil filler cap even after it sits for the winter storage season. But if you run it and it never warms up that can happen. Make sure your thermostat is not sticking open and the engine actually comes up to at least the rated temp of the thermostat. Some are 160 units and some are 140 units.
your testing with a gas, so it has a lot of kinetic energy if you saw zero pressure drop with temperature same than it checked good. if you used water (can't on combustion side) the you would see a drop immediately. when mine holed through it put 5 quarts of water in pan in about 5 minutes so it was quick. testing with air is extremely dangerous. you are creating a grenade. do not go above 20 pig!!!!!!
Thank you all.
Changed oil twice, ran on the hose for 20 minutes. So far no water in oil. I will finish putting the thing together and will take it on the lake this week will update you all when done.
Thanks a lot all of you, really helpful.
I would think you are out of the woods then. When my neighbor didn’t winterize his master craft and it pushed a core plug out , he got one or two uses before the crack opened up, so if you got it good and hot you should be ok.
