04 subaru forester xt oil cooler non typical leak fix. 

I tried the common leak fix first at the cooler and that didnt fix my issue, had to remove sandwiche plate for oil cooler and replace the remaining 3 upper seals and that fixed my leak, by the way its not 6 6mm bolts its 6 10mm bolts, the black upper plate has its own bolt its a 21mm tighten that first then the other lower plate with the 6 bolts then the oil cooler and everything else in reverse order, dont forget to check your oil cooler hoses for cracks or inflated hose or else if those fail you will need head gaskets.
