As stated above, nature of the beast - life with forced induction. Not sure about the Raptor but on both my 3.5EB KR and 5.2L FPC you only really need the catch can for the passenger side. I check about every 1K miles and might have 1.5oz in the cans - so no serious impact on the oil level(s). My main concern was not allowing the oil saturated air flowing back through the intake and building up on back side of intake valve. This was supposed to be remedied by Ford with the 2017 model Eco Boost (3.5 non Raptor)engines by going with both direct and port injection...
Supercharged 6.2 here. I haven't gotten any oil out of my driver's side can. I was told this before installing by the guys on this forum but I decided to go ahead with it out of an abundance of caution. As I plan to keep this truck long term I wanted to keep it running clean. Now that I have seen for myself I would probably skip the 2nd can. But I don't know how these new higher pressure high output 3.5s are with this issue.

Again, this is not going to be enough to wreck your engine, especially with the port injection (hope you guys are running your Techron!) but if you plan to keep the truck more than a few years you really want to keep this junk out of your intake and off your valves.
Agreed, cheap insurance in my book!

its next to impossible to get a OEM catch can approved for street use on a production vehicle for environmental reasons. Also no one at corporate wants a small disgusting gooey can that requires periodic draining to be added to the list of maintenance items when no one else on the market requires it. Despite its benefits.
The only disadvantage to the factory PCV system is decreased intercooler efficiency in high mileage engines as they start to be coated with oil. The factory PCV system also (on paper) has the ability to PRODUCE more hp because of the negative crank case pressure vs a catch can or a VTA system.

I agree if there is real data.
I keep my cars to 200K miles and this is a $500 project that no one can supply the ROI numbers.
1. Real data on oil used or "Catched" is good to know.
2. Can the engine go to 200K (No can) and what is the damage at say 150K miles with out installing a catch can?

oil pulled through the intake by the factory PCV system will never cause valve problems on the new EB engines since it has a port injector spraying the backside of the valve keeping it clean. This was HUUUGE problem with direct injected only cars like BMW, Subaru (FA20DIT), early Toyotas(lexus) ETC where they were DI ONLY cars and there was no port injector to spray the back of the valve clean. Our biggest problem is coating the inside of the intercooler with oil over time.

the factory PCV system will have almost zero impact on engine life other than lowering the efficiency of the intercooler marginally at high mileage on a truck that isn't raced regularly. The catch can is a good idea because the intercooler essentially acts as a catch can in the factory system. Separating moisture from the oil vapor. But it has zero impact on engine life either way.
The reason we run catch cans on our race engines is because the oil vapor can cause a fluctuation on the octane rating in extreme extreme cases. and we need every scrap of intercooler efficiency we can get do to size constraints.
