Hello, the back story:
I bought this can non running after 7 year hibernation. Not much information about it. I did the leak down test before purchase and all cylinders checked out fine. After finishing the necessary assembly and repairs that you can read about in my other threads i fired it up. As soon as it warmed up and the thermostat opened i got oil coolant mix burping out of the cross over bleeding outlet and in the overflow tank. It got dark so i had to stop for the day. The newly replaced oil is clear, no sign of coolant. But it seems to disappear based on the oil level. I suspect the oil cooler seals. What is the best way to verify that? It could also be the head gasket but the plugs looked good and the engine seems to run fine and does not overheat.
