It IS possible that the filter housing has porosity in it. That COULD explain oil seepage at high rpm only.

It could very well be oil filter gasket seal, spraying as oil pressure goes up at high rpms. Had it happen to me. Possible?

The filter housing is new, but that doesn’t mean it’s ok. I’m not seeing any oil on the housing itself though. Looks like it’s mostly on the filter and sending unit.

This is what I’m thinking, but I wasn’t sure of the likelihood. I wonder if a fix could be as simple as tightening up the oil filter some more? It’s hand tight right now.

The pattern on the oil pan is throwing me off. It could be spraying against the pan, collecting and dripping down. There is a tiny bit of oil on the starter, but nothing substantial.

You can try tightening it more, my guess though is the seal is compromised. I would at least take filter off, and look at it, although sometimes its hard to tell, just by looking at the rubber seal.

Just thinking. Do you have a spare oil filter housing? Make a block off plate to seal block side,screw on filter you are using and pressurize it with air slowly checking for leaks.
