Radiator Leak?

I have had missing coolant for a while, and sometimes it shows up under the truck on the drivers side on the corner of the radiator. I determined that the hose was the problem as there was always fluid on the upper radiator hose. I replaced it. Now that it is replaced, I still see red coolant sitting on the top seam where the black cap is crimped to the metal radiator. I assume this means that damn thing is seeping at the crimp.

This means radiator replacement as far as I can see. But, my question is, do I go with OEM radiator or Mishimoto? With shipping, an OEM will be close to the Mishi.

I bought once from performance radiator and have had good results with it. It also has a lifetime warranty. Its all aluminum so no plastic parts. Its also said its the same one that BPD resales.

The plastic top crimped location failure is common for F series trucks. I had the same thing and put in a BPD radiator. No issues with it since.

I'm on my 3rd Mishi. I'm at 108K with this one now (the updated version) and no problems. Not sure I'd go this way again though.

iirc my factory radiator went about 170,000 before it started smelling ad leaving residue at the top seam. I put another factory one in.
