It does not matter to me if you go the route of brethers or a catch can, but the passenger side does indeed produce the oil mist.

And for the record, it runs just fine; nothing wrong with it. To anyone who thinks this is too much, simply google it. You'll find for yourself that these engines (and others) do indeed create oil mist, and the catch cans or breathers will keep it from entering your intake.

Here's a few links to read on your own:

I'm not going to argue with you. I know what I'm talking about, didn't get to the level I am without it. Throw a power adder on there. Or a real tune and drive it like its intended to be. And watch how long it runs right.

I'm not arguing with you, nor am I doubting what your talking about or your level. Both a breather or a catch can work, but you don't have to have them on both sides of the engine. If you want to, go ahead.

However, it's only required on the passenger side. Trace it out. Drivers side has a tube that draws the air into the crankcase, passenger side routes the crankcase fumes (and this is where the oil mist exists) to the intake to be burned. This is what we want to prevent.

Your method works with breathers, as well as a catch can. I can certainly say this; there is oil mist on the passenger side. I empty the catch can once a month. I may be harder than most with mine; I track it a couple of times a month at a local private airport. It's my daily driver, and weekend play toy.

You'll need some block off caps for the tubes that you are removing. The breathers themselves, you can perhaps look at this kit for ideas on how to mount yours:

Or this:

Gotcha. I posted the links as I figured they might have the blockoff caps sold perhaps seperately, or maybe listed in the link as to their size. Or, it would give you some ideas on a search.

Here's what I found: You'll need 1/2 inch caps to fit over the 1/2 inch nipples when the stock tubes are removed. Here's one link to a site that sells them (6 bucks for 10; can most likely find them at an auto parts store):

The block off caps are 1/2" rubber vacuum caps. Problem is, I couldn't find a pack of caps at my local parts stores that would fit so I found a cooling line cap kit that had a 1/2" fitting. Essentially the same thing, a little black cap with a half inch opening. You'll need two; one that fits on the underside of your throttle body and another that fits on the port on the intake. Simple stuff, don't overthink it!

The filters I used were the ones you find at any parts store - spectre breather filters part number 3991 (black) or 3992 (red). Take a 1/2" drill bit and widen the hole in the rubber so it will fit. Make sure to get all the rubber fragments out of the filter before installing it - duh. Hose clamp them on.
If you think your passenger side sticks up too far (the blue one, you'll see what I mean), trim it down about half an inch. While you're at it, take out the blue PCV valve altogether and pull the black ring off the bottom end of it and pull out the checkvalve that is inside it (sorta pointless to run a breather filter with the check valve in place).

Autozone, O'reilly's, Advance Auto, Pepboys outta have everything you'll need - except maybe a good sharp knife to trim down the passenger side pcv valve.

Awesome, very helpful thank you. Although telling someone trying to learn to do their own mods, rather than pay a shop an outrageous amount, on their $35k vehicle "don't overthink it" is a little moot lol.

Yes, this. Only one nipple gets a cap, as the other end of the stock hose you'd be removing gets the breather installed on it.

Passenger side: remove the hose that runs from the passenger engine head cover to the intake manifold (this is the side that the oil mist is culprit). Install a cap on the nipple of the intake manifold, and install breather on the nipple on the passenger engine head cover (nipple is the PCV valve).

Drivers side: remove the hose that connects from the drivers side engine head cover to the fresh air intake (near the air cleaner box if stock; CAI is simular). Cap the nipple on the air intake side, and put the breather on the nipple at the drivers side engine head.

The picture by DEERSLAYER in post #5 (or copied in post#34) shows the breathers installed on the engine head covers. The other end of the removed tubes from these locations are what you will have to cap off.

The 5.0 and 3.7's don't really have a "valve cover" per say, but rather a engine "head cover".

Hey guys quick question. I'm looking into getting a breather kit set up for mine and checked out JPC racing and it looks like they use a K&N set up. I'm wondering if anyone knows if these ones on Amazon ( K&N 62-1495 Vent Filters) are the same ones JPC is using. I'm getting my valve covers off to powder coat and replace the gasket this weekend and think amazon may be able to get me these breathers faster than JPC.

OK, probably a stupid question... Can you modify to do both. AM has a Moroso breather that looks like has a catch can. If you bought a cath can and spliced in a breather after the catch can would this work well? Help? Overkill?

The one on Amazon I looked at said it "Fits threaded Ford valve covers". I guess it would just screw in there haha

Not as " high tech " as your breathers.
Have the same set up on my 11, does just what it's supposed to do, catch the oil blow-by.
.

.
.........8500 + miles on the 11 tells me I don't need one on the driver's side.

Exactly the setup I have...Bought the air compressor "water trap" at my local Lowes for 8 bucks. And yours is collecting the oil mist as well; more than a few tablespoons...

You have to take the fitting off the valve cover to get it out. Just use a small screwdriver once its off to remove the check valve
