To me, i would suspect OPRV problems are the source of all of your woes. You blew off an oil filter due to exessive oil pressure, then added oil and blew another one? Oil cooler seals are probably a second symptom. Putting a new oil pressure sender before doing the seals and OPRV is just delaying the inevitable.

Take a minute and consider this- the oil cooler is difficult to access with the engine installed. You blew two filters, so we know we have an OPRV problem. You have coolant in your oil now, which means the milkshake has coated your rod and main bearings. Porsche recommends the bearings be changed when the cooler seals go.

I guess what I am hinting at is... How old is your clutch?
