it's keeping oil from getting in the S/C system.
Is that a bad thing, though?

My take is this..... while a little bit of oil getting into the intake isn’t going to be a disaster, a can isn’t going to hurt and it’s a good way of assessing your motor. A tight motor that has a good seal around those oil galleys in the cylinder head is going to see almost no oil at all in a can. If you have increased your boost with pulleys and you don’t have a good seal there, then you’re pressurizing your crank case and a can is a good way to check that. I have one of these...... 259C51A9-EB32-4169-9C48-F45DD5547ACB.jpeg 7B44DE8A-1DF3-4179-87D0-B5E81C1F02DA.jpeg 974E6D00-E9F0-4EDC-8CAB-EC128A9D8A3D.jpeg

A loose motor revs faster. Oil in the catch can doesn’t mean the rings aren’t seating?

Why does this happen with the 6.2? The 6.2 is port injection vs direct injection...so I'm assuming it is somewhat normal? I agree that it cannot hurt to keep things clean with oil catch can.

I didn’t say it was rings. The cylinder head uses o-ring intake gaskets and the ring around the oil galley is known to be commonly compromised. That oil galley leads to the crankcase. Engines that see a lot of oil in a catch can, most likely have a problem there.

That's where I think the FI spacers can help that issue ^^^.
I don't get that much oil in my CC , maybe 1 tea spoon but I still would not run with out it.

I don't think it's catastrophic , but I don't think it's a good thing , if your car is 1 of the ones that get a lot oil in the Hellcat S/C system or intake system on NA cars ?.... then it could lower your effective octane level when it's trying to reburn that. Not to mention a oily mess inside those systems too.
I just don't see the down side to using a CC.

I guess I need to replace them on my 5.7 because there is some oil accumulation on the top edge of the heads between the intake and valve covers. I guess it’s to be expected after 137,000 miles!
