How did you know it makes me sleep Like a Baaaaby LOLIf it makes you sleep better at night.
You might get a few drops if you constantly redline your car or your track it really hard on a road course.
I only track my car, 17 pp1 with 305/35/18 nt01, and before putting the aluminum gt500 valve covers, I was getting a lot of oil on BOTH sidesIf it makes you sleep better at night.

Can please someone explain to us - less knowledgable members - how the side of the engine can influence the oil steam buildup?
In the old days, one side went to the vacuum of the intake manifold to be disposed of while the other side went to a clean air source like the airbox so that air was drawn in one side and purged out the other hence one side will get all the vapor/blowby while the other side is simply an air intake. The intake side would only see crankcase vapors if blowby exceeded manifold vacuum or if the engine shuts off and the vapors exhaust up into your air filter. If Coyote works different I'm sure somebody will be along shortly to correct me.
Yep, the side with the PCV valve is the one you want. I don't race either but after 1000 miles, there's a couple ounces of oil in it. So I personally rather not have that oil in my intake manifold or cylinder head runners up to the intake valves.
I m think about the catch can on my 2021 M1. I m a little worried about the need and then adding pressure issues or a clogged line with freezing weather. I ve search all this stuff and still can t come up with a clear path. If anyone wants to expand I m all ears. Street driven only.
People vastly overthink it. Ford produces a motor they are willing to warranty without it. The junkyards aren't filled with a bunch of Coyote powered vehicles that just gave up the ghost at X miles. PCV has been on motors well back into the 70's at least and it hasn't been some sort of massive motor killer. Why would it all of a sudden become the end of all motors just for a gen 3 Coyote?
The oil separator (aka "catch can") isn't for longevity of the engine. Not having one won't have any effect in terms of causing damage to an engine or affecting it's longevity. It just prevents the oil vapors from condensing and coating the insides of your intake manifold runners and ports. Depending upon the engine's design, some will actually pool oil in certain spots in the intake. I've pulled many intakes in my career and some engines have much more oil than others. That being said, I really hated when I removed an intake and had oil dripping all over the place. While no one has reportedly tested to see if there's any performance issues (seriously doubt you'd notice any reduction caused by the oil vapor, etc.) it's just nice to know that all the oil in the reservoir trap that I empty out every so often ISN'T getting into my intake system.
It certainly won't hurt anything, but I believe it's a solution to a problem that doesn't exist. The only manifold I pulled that was drenched in oil was one where the PCV valve had failed and stuck open. Other than that there was the usual higher mileage maintenance on the old 5.0 where you had to scrub the backside of the throttle body for oil residue but it never really had an affect on the motors drivability.
