leaking oil cooler (not the o-ring) 900

I know this is a long shot, has anyone ever sealed a leaking seam on a 940 turbo oil cooler?

Note - this is the cooler itself, seam where the seal retainer ring meets the face of the cooler on forward side.

Car has been leaking substantial amounts of oil the last couple of months. I replaced the distributor - which was one source. Yesterday I removed the oil cooler & replaced the green o-ring between the extender & cooler. Once back on the car, while I was refilling the coolant, I noticed what appeared to be oil seeping through the oil cooler just below the o-ring.

This morning I finished putting it all back together & watched underneath after starting the car - sadly I saw what I had feared, the oil is coming out of the cooler itself, leaking through the seam.

Anyway, guess I'll be looking for a replacement oil cooler (the round version, have seem others on the web) unless there is a high temp epoxy or if JB Weld would hold up under these conditions.

Thanks
