Guys, I think I know what is the problem.
As engine and oil gets hot, oil pressure starts dropping until it goes to zero.
Then I stop the engine and the dry sump tank is about 3/4 full.
Could it be that the oil pump creates a vacuum and causes the hot oil softened intake hose to collapse?
I have earls 12 hoses and fittings. That hose dont look very strong to hold vacuum.
