I was changing my oil yesterday and saw a decent amount of oil on the bottom of my oil cooler but not from the filter i could not feel any oil on the top of the oil cooler and i sat around with a mirror trying to find a leak but that didn't work out to well. There is oil all over the pressure sender. I know its is not coming from the valve cover. and i don't believe its the head gasket. Anyone ever had a leak like this? is it possible that it is leaking from the pressure sender and getting alittle on the bottom of the oil cooler. My next step is to take off the intake manifold to get a better look if no one has any other ideas. Thanks for any help

 

Hose it all off with brake parts cleaner (use goggles or look away with eyes closed when you shoot). Clean it real well with the brake cleaner and rags. Run it to get the oil pressure up (70-80psi). Check it again for the leak, looking for fresh oil drip/accumulation spots.
