[MR2] Oil cooler bracket replacement

This past weekend I replaced the turbo down pipe with an aftermarket one from JP Autoworks. This is on a 1993 turbo MR2. In the process, I removed the oil cooler. When I took out the relief valve tube, I noticed some shreds of aluminum on it. This made me think maybe it was cross threaded before.
When I went to put everything back together, the relief valve began to thread fine, but would get bound up every time. I tried cleaning out the threads on the bracket and using some oil on the relief valve threads, but the same thing. I got the tube snugged down by hand and then used the torque wrench. Once I applied ~25 - 35 ft-lbs, it spun. In a moment of hope and desperation, I thought maybe there was enough torque on the relief valve and tried running the engine for ~5 seconds. It leaked oil and antifreeze very quickly.
Getting the new down pipe in there was a lot of work. I am now wondering if it would be easier to pull the engine to swap the oil cooler bracket and drain all the engine fluids. I could also fix any other leaks and do things right.
Any thoughts or insight would be great!!
