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......
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!
