Product Description

JLT Passenger Side Oil Separator Kit for all 2011-2015 GT and 2012-2013 Boss 302 Mustangs.

JLT Performance's newest product to keep oil out of your intake is the oil separator. During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors, can coat your blower rotors, intercooler fins and even dilute your gas, lowering its octane level.

Milled from solid billet aluminum with a black or clear anodized finish, this is a rock solid piece. It has a knurled tank base for easy removal to drain the spent oil and an O-ring seal to prevent any leaks. JLT took this unit a step further and added a Ford Motorcraft metal mesh PCV Pre Filter element. This element collects the last bit of oil droplets and drains back into the tank when the engine is shut down. JLT has also included a factory PCV hose for an easy plug and play installation.

*Will NOT fit superchargers.
*The tank holds 2 oz. of fluid, while that may not sound like a lot, you shouldn't see that much oil in your PCV system. Drain it every oil change and you will never come close to filling it.
*Most of the oil will come from the passenger side, so if only getting one oil separator, this is the one to get!

Great fit and looks great!
This is a fantastic looking product that has quality construction. Installation took literally about 2 minutes. Haven't had it long enough to empty it yet, but having it there is good piece of mind on my new 2015 GT. So far I am highly satisfied. Will check the canister soon to see how much oil is being collected. 2 thumbs up!!!

Works great and easy install.
I pre-ordered this before my 2015 Mustang GT came in a month ago. Quick install and works great.

Just do it!
This is one of the 1st mods any coyote engine owner should purchase as this little device catches a lot of oil. In just 1,000 miles I've dumped my can 3 times which accumulated almost a half quart of oil, I don't want that going through my intake! This took no more then 15 seconds to install and requires no technical skill, just do it!

Driver side JLT
What these units do is keeps the engine from sucking in oil and gas vapor directly into your intake causing a drop in Octane and sludge build up. The short version of the PCV job is to take air in from the cold air intake and run it into the drivers side PCV it then circulates around and exits the engine on the passanger side. From there it goes directly into the manifold to be re burned as an emissions requirement. Sounds fine unit is starts sucking oil into the manifold! This picture/diagram is the drivers side one that is why the air going into the engine is filtered right before it goes in. The JLT unit for the passanger side (and the only one you REALLY need) is the opposite. The vapor/oil is strained through the filter FIRST then the claen air with vapor goes into the intake maniolf to be burned off. The filter catches the oil and lets it slowly drain into the canister to be removed later. Let me tell you these things work!!! I catch 1/8 inch worth in 500 miles which goes back into the engine!

By Bill Tumas: While EcoBoost platform is new to a lot of Mustang enthusiasts, one of the nice things about the 2015 Mustang GT is many of the things that we learned from the 11 through 14 are going to carry over. One problem with the 11 through 14 Mustangs, they tend to suck oil into the intake through the PCB system. Trace amounts won't cause any problems but the more oil you draw through, the more chance there is a permanent damage to your engine. Thankfully there is a very easy fix, the JLT performance oil separator.

This JLT performance oil separator is going to mount to the passenger side of your 2015 Mustang. There are versions for both the driver and passenger but between the two the passenger definitely draws a lot more oil through than the driver's side does. JLT makes the installation very easy by using factory Ford tubes and factory Ford fittings making it a very easy installation.

The oil separator itself is a billet aluminum housing that will hold two ounces of oil. While that may sound like a lot, two ounces is plenty for this application. JLT features a narrow bottom making it easy to unthread and drain out. They also use a Ford factory PCV pre-filter which will hold the oil before draining it into the container.

When I got my new 2015 Mustang I knew the JLT oil separator was going to be one of the first modifications I was going to do. When I had my 2011 last summer I took the car cross country. When I got out West I checked it, I had almost a quarter inch of oil in the bottom of the container. I drained it out and when I got home, almost the same amount. The JLT truly works.

Because the JLT uses the factory Ford line with the factory fitting, the installation is actually a breeze. There's no tools required. We'll start over here on the passenger's side valve cover. To remove the passenger's side valve cover, simply push up on the gray clip and it will slide right off. The other side of the intake release is the same way but you will have to pop the intake cover up to get your arm in there. Here you can see the stock line verse the oil separator. Again you can see stock Ford lines make for very easy OEM installation. Again here just slide on to hear it click into place. That's all there is to it.

The JLT oil separator looks OEM when it's installed and knowing how valuable it was on my 2011 made it a must have on my 2015 as well. Installation couldn't be easier, it will only take you a couple of minutes you'll be back on the road in no time.
