Back in 2020 when I did my first oil change on my '19, I installed a Toyota metal housing. Despite not being thrilled with how it seated with that "feel" that it was " tight enough", it was fine and didn't leak. This past June I did another oil change, buttoned everything up and again no leaks. Until yesterday when I found a small puddle of oil. The oil was coming from the housing-to-base seat. I checked that it was still tight to spec, then dropped the housing, checked and cleaned up the threads, installed a new filter and all o-rings, torqued to spec and it began to weep as soon as I fired her up. Befuddled, I dropped the metal housing, installed the OE factory plastic housing, made a short drive and she's dry as a bone.

Anyone else have issues with the metal housing? The metal housing held up fine for one year through that 1st oil change as well as nearly 3 months after the 2nd. Strange...
