My new build has been running great, but I've been trying to diagnose an oil leak that seems to occur at higher RPMs. I figured the rear main was toast, but looking at where it's splattered I'm not so sure.

I put some UV dye in the oil and it looks like the leak is concentrated on the passenger side on the filter area. There is oil down the passenger side rear of the pan, but it doesn't look like it's originating from the rear seal area and the flex plate doesn't have the oil flung out from the center. There is oil built up on the passenger side corner of the pan, but a bulk fo the mess It looks like it's coming off the filter or sending unit. No indication of leaks from the valve cover or distributor and it doesn't leak when it's sitting.

Has anyone seen an oil leak from the filter or sending unit under high pressure before? My gauge hits 80psi above 2500 and idles around 45psi. It doesn't appear to leak - or is way less severe - cruising around town below 2500.
