Hey just an FYI/update on this JLT catch can & changing it- I just got 1-2oz out of it (I empty the catch can every oil change) & one thing I noticed was there was oil residue around the canister & the fittings- the canister had actually backed off a couple threads, wasn’t entirely sealed- it did same thing last oil change…but I also didn’t hand tighten nearly as tight as I had on previous changes b/c it was a PITA to get off…well….i didn’t throw any codes & was still doing its job but from now on I’m gonna make sure it’s plenty tight when screwed back on & id recommend you do the same lol
