The cooler can flow both ways, the filter does not.
The eternal optomist that I am, I am going for the notion that the motor isn't screwed up after running it for exactly 2 minutes under no load, with a full
oil pan but no pressure. I'm going to change the
oil, and remove the valve cover gaskets before I make a decision on dropping the pan.
Any of you other optomists please feel free to chime in as I am still in a mild state of panic.
