Ecoboost PCV or Ford Performance Separator?

Greetings fellow stangers,

A little history about my car is its a 2014 model 5.0 track pack with currently around 48k miles. I bought the car with right at 5k miles on it bone stock and at that point the only mod I did was add a roush exhaust. Fast forward to about 20k miles and then I went a little further with it deleting the resonators and installing an offroad x pipe () as well as a JLT cai and Lund tune which is where it sits performance wise today.

I've been on the fence about adding an oil separator for quite some time but Im wondering with the currently mileage on the car if its something I should still consider? Looks like most owners do it at much lower mileage than mine.

The second question I have is I was reading up more on it and it looks like the ecoboost pcv from a F150 ecoboost is an alternative solution for a catch can set up. This route appears to be much cheaper, no need to worry about dumping oil from a catch can, and looks as stock as you can get but this is one of those things I want to do right the first time and not look back. I cant verify myself but one of the posts in one of the threads I was reading stated that this is what comes on the 2015+ 5.0s. Anyone can validate this? If thats the case that'd make me feel more comfortable going this route.

Last question is has anyone had time to accumulate enough miles to do testing on the Ford Performance oil separator? It appears to be a fairly new unit and would like some feedback if its worth the purchase or not. I know alot of people recommend the JLT one which I think is a nice looking unit as well and I understand that they updating the hose fittings but I still dont like how it just hangs there with no support brackets as well as read that oil still goes past it. I assume to dump the Ford performance one, you take the whole unit off each time, dump and clean it, then reinstall? Its not a big deal to me but I just havent been able to really find much info on it but I like the looks of it as well as it looks to be actually mounted.

I'd really appreciate any help I can get. If the ecoboost pcv is sufficient, I will more than likely go that route instead of a catch can due to the OEM look but I dont want to change this out then cause damage to my engine long term. If not, then the Ford Performance one will have my money but I would just like a little more general feedback on it before I spend the money.

I can only speak for the bobs can. I had trouble with customer service being a ****** but the product is great. It isnt hard to empty the can, I have mine at the firewall and not the regular location also. Just stick a dixie cup under and open for a few seconds depending on how long you go. I didnt have any oil in the return hose when I took mine apart but that was only after like 400 miles. Also looks good in the bay. The bobs is proven so I wouldnt want to try to test out any other brand.

You can go with the GT500 one as well. It's the same as the one in an Econoline van so it costs about $15. You just need to trim off the electrical connector. Does your car use oil? Because if it doesn't, then the need for a catch can isn't there. Frankly, this is a manual trans thing in my mind. My current auto car doesn't use any because it doesn't hold gears and spends a lot more time at low rpm than my old stick car did.

How is the PCV valve from an Ecoboost an alternative to a catch can?

When I was researching which catch can to get for my Ecoboost Mustang I read a number of threads on F150 forums and it seems that a catch can only the 3.5 Ecoboost is one of the first modes for that engine too.

I have a JLT I just put on my coyote last week. Car has 29k and in the week it's been on it has collected enough oil to make me think it should empty every 1500 miles or so. If you have a manual get a catch can. Mileage has no bearing on whether you need one or not.

Oil in the intake will lower you fuels knock resistance.

+1 JLT catch can. It was my first mod and after 1800 mile drive from Tampa to Denver it was 1/2 full. There is now a recommendation by FRPP to do a catch can as it can lower the octane rating and cause detonation when using tunes.

I've had the Ford Performance catch can on my 14 GT for about 1,700 miles. I just emptied it a couple of day ago with about 1,475 miles on this run and it had about 1/2 oz of oil in it.

To empty it, I just removed the two push pins and removed the lines from the PCV valve and intake barb and lifted the entire thing off. I then removed the inlet line and poured the oil out the intake barb. Very easy and did not take any time at all.

This thing holds just under 7 oz's so you could run it an entire oil change before emptying it.

I can't speak to the ecoboost PCV since I don't know anything about it.
