i had some 'weeping' from my lower oil cooler hose, so replaced it this weekend. the aluminum oil cooler threads were totally MANGLED, so i immediately consulted the forum and considered my options.

MY SOLUTION after some trial + error "research" was to pull out a 22x1.5 DYE and take a deep breath. My oil cooler now has 4 beautiful threads on what once was a pretty sloppy mess. It took quite a while to figure out the right thread diameter/pitch, but that's it: 22 x 1.5.

yeehaw.
