Anyone use Earl's Oil Coolers?

Easy Steve, I'm not knocking the Tru-Cool as a viable option. It's cooling the oil well, and if there wasn't a bit of weeping at the one fitting, I'd be 100% satisfied. The price is certainly right at $40. However, the 'one time' crank down of the NPT fittings to get them pointing in the preferred direction screwed me. After speaking with the company, it looks like a bad batch of Permatex thread sealant is the probably culprit. I emailed Permatex and they believe it could be past its shelf-life. So I have a slight weep from one NPT fitting on the cooler. Having had to crank the fitting to align it properly was, as you noted, a one-timer. I can't just unscrew it and try again. The other cooler options (Earls, Mocal, Setrab) are available with -AN fittings directly on the cooler. This should make it easy to reinstall the fittings if ever necessary. Also, they have more robust mounting brackets.

While the Tru-Cool certainly stands up to the cooling job, I'm amazed you don't find it flimsy. Seriously, one finger is all it takes to push on the mounted cooler and bend its mounting flange.

Sure you can. I think you misunderstood my "one time" statement. Once you get it in position you don't want to move it again and break the seal. Since your seal is not sealing, There's no reason you can't unscrew it, clean and reapply the correct sealant as long as you haven't ripped the threads out of the cooler from over torquing......I re-did mine with no issues, and recently took apart one put together 8 years ago (to my design) because we had to reinstall it on a different side of the car and re-orient the fittings 90 degrees.. No leaks, no problems.

And NO, I don't find it flimsy..
