      Video Review & Installation

      Hey guys. So today I'm here with the JLT V3.0, Driver Side Oil Separator in Black, fitting all 2012 to 2018 JK Wranglers with the 3.6-liter V6 engine. So this is going to be for the JK owners with either a stock or modified engine looking to reduce that blow-by and increase the protection on your engine, essentially increasing the longevity with a high-quality mod. So with a system like this, essentially what it's doing is capturing all those oily vapors that are created in combustion, separating the oil from the air, catching all the oil down in this catch can here and rerouting that clean air back into your PVC system. So without a system like this, what's gonna happen is basically those oily vapors could potentially get into your intake system and gum up your valves, which can decrease the lifespan or the longevity of your engine. So this option by JLT is going to eliminate that with a high-quality design and a high-quality modification here. So this is gonna have a solid design. And it's made of a billet aluminum construction and has a nice black anodized finish on the outside protecting that aluminum underneath. And on the inside, it's gonna have a honeycomb filter and a mesh screen to optimize that filtration.Now what I do like is the fact that this has a higher capacity than JLT's previous models and some other models on the page with the 3-ounce catch can down at the bottom. So this is gonna decrease that maintenance over time. So you're really only gonna have to empty out the catch can, all you have to do is screw off the bottom and empty that every 5,000 to 7,000 miles in comparison to some of the other options with a smaller capacity that you will have to essentially maintenance more. So I do want to mention that this is not CARB certified so if you do live in an emission restrictive state, I would keep that in mind when shopping around for oil separators.So this is gonna be roughly $140. And I personally think for the functionality as well as the high-quality design that it fits very well in that price point. So other options on the page, there's not gonna be a lot of choices. But this is gonna be your only option with the highest capacity that is also specific to the 3.6-liter V6 engine. Other options on the page may be a little bit more generic, fitting a couple other models. And then some other options, like I mentioned, are gonna have those lower capacities. They may have 2 ounces or a 1-ounce catch can down at the bottom. So overall, I do think this is a high-quality field. It's definitely worth the money. And it's very easy to install. It comes with everything that you need, you even get this little bracket over here that's gonna be the same build as the catch can. It's gonna be in an aluminum construction with a black anodized finish. And it even has JLT at the top for a little bit of branding and style inside your engine bay.So speaking of that install, it's gonna be very easy again at one out of three wrenches on the difficulty meter. It's probably gonna take you about 15 to 20 minutes to get this thing installed. And you're gonna need some basic hand tools. So speaking of that install, let's jump into that now. The tools that I used for this install were a Phillips head screwdriver, a flat head screwdriver, a 3/8-inch drive ratchet, and an 8-millimeter socket.So our first step is to obviously open our hood and then we can go ahead and pop our engine cover off. It's just gonna be held in by a couple of grommets. So all you have to do is lift up and we can get that out of the way. So our next step is to mount up our bracket. So we're gonna remove this 8-millimeter bolt here with an 8-millimeter socket. So after we have that removed, we can grab our bracket and sandwich that in between and reinstall that 8-millimeter bolt. Once you have that threaded in, we can just tighten that down with our 8-millimeter socket. So after we have the bracket mounted up, now we can mount up our oil separator.So what we're gonna do next is mount up our oil separator. You wanna make sure that the lines are facing the front of the Jeep since we are going to route it underneath our intake tube, and that the T is facing the front and the J is facing the rear. So what we can do is kind of get these lines out of the way and in position before we go ahead and bolt this up, make it a little bit easier. We start to wrap these underneath the intake tube. So once those are underneath the intake tube and we get our oil separator in place, we can grab the provided Phillips head screws and screw the oil separator into our bracket. So once you have those threaded in, we can take a Phillips head screwdriver and just tighten those down. So after our oil separator is tightened down to our bracket, we can move on to the lines.So what we wanna do next is disconnect our PCV pipe. So we're just going to pull back from our intake, disconnect our tube here. We need a flat head screwdriver to kind of push this off. You might have to just twist and pull. And once that's off, we can attach this side, which is gonna be the male side to the J portion that we just took off our factory PCV. Then go ahead and pop that back on to where it was originally. Then we can take our other line and we can connect it to the other side where we just disconnected that coupler. So after that's seated and in place, we can just pop that back in to where it was sitting on our intake.So after you have all your hoses connected, we can go ahead and pop on our engine cover. Just press down and it'll pop into the grommets. And then we can close up our hood and then you're all set to go. So that's gonna wrap it up for my review and install.

      Don't Dilute your Octane Levels. During the process of venting crankcase pressure back through your intake, large amounts of oil vapors can coat your intake tube and even dilute your gas, lowering its octane level. This happens in all engines, but even more so with forced induction systems. To combat this, JLT has developed the all new Version 3.0 Oil Separator. The V3.0 Oil Separator holds over double the old version. 3 ounces of fluid might not sound like much, but drain it every 5000-7000 miles and you won't come close to filling it. It also features a new multi stage filter designed to collect the finest of vapors.

      Lasting Quality. Milled from solid billet aluminum, the JLT has a knurled tank base for easy removal when draining the spent oil, and an O-ring seal to prevent leaks. Filtering is done by a fine mesh stainless steel screen that traps fine oil vapors. They then pass through a 1/2" thick 1/16" aluminum honeycomb filter where oil collects before dropping into the 3oz tank. JLT then completes their Catch Can in a durable black anodized finish for aggressive good looks and long lasting corrosion resistance.

      Easy Installation. JLT Performance engineered their Separator to be installed in under 30 minutes with just basic hand tools. This kit comes complete and includes two PCV lines with stock-style quick-disconnect fittings that allow for an easy plug-and-play installation. All the necessary parts are included with no cutting or extra modifications required.

      Not CARB Certified. This JLT Performance Air/Oil Separator is not CARB certified at this time; therefore, it is not legal for use in California or other states adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

      Application. This JLT Performance Version 3.0 Black Driver Side Air/Oil Separator is designed for use on 2012-2018 3.6L Jeep Wrangler JK models.
