      Video Review & Installation

      The JLT 3.0 Driver Side Oil Separator that we're talking about here today will be for the 2015 and newer EcoBoost owners who are looking for the ultimate protection in regards to capturing and isolating the oily vapors produced during combustion and blow-by from being rerouted back into your car's intake track through the PCV system, and this can lead to a bunch of issues that we'll talk about in a minute. Now, as for your materials, we're talking about a three-ounce capacity here billet aluminum for the container itself, while you're also receiving factory-style hoses and connections for right around the $140 price point. Installation here, gang, is gonna be a simple plug-and-play job, thanks to those factory-style connections. So, therefore, we'll call it a solid one out of three wrenches on the difficulty meter here. Maybe a few minutes of your time from start to finish, but if you hang with me for a little bit I'll show you more on that install later in the video.First and foremost, I do think it's very important to talk about the benefits and the purpose of running an oil separator or a catch can on your stock or modified Mustang, but especially on an engine like the 2.3 EcoBoost, which is only direct-injected. Now, you see on traditional port injection setups or even dual injection setups, that port-style fuel injector is gonna be responsible A, for fueling, of course, but B, they also helps keep the backside of those valves clean and free of any deposits. Now, that's where this little guy comes into play. The JLT is gonna help capture and isolate all that oily junk or blow-by that is produced during combustion from getting rerouted back into your car's intake tract. And at that point gumming up your intake manifold, and even in worst case scenarios leading to what is called valve coking. And that is all this junk gumming up the backside of those valves, which doesn't otherwise get cleaned off by a port-style injector.Instruction is gonna be extremely solid here at the JLT option that does include the neural billet aluminum canister, 3 ounces of total capacity hence the 3.0 name, along with that JLT logo etched into the top portion of the canister itself. Now, this particular option does feature what JLT calls their clear anodized finish. Basically, it's a satin silver that really shows off that raw billet aluminum. I think it's gonna pop a little bit more under the hood but, on the other hand if you preferred something a little bit more stealthy, you could always opt for JLT's black version instead. They are gonna kick in a black bracket for mounting purposes under the hood. That certainly helps, but maybe my favorite part about this kit besides its actual function, is the fact that they include these nice hoses in factory-style connectors pre-installed for you ready to go right out of the box, and just gonna make for a very factory light bit and finish, but also a very easy install as well as we'll show you here in a bit.As far as emptying the canister itself, JLT is gonna recommend once every oil change. But judging by some of our customer reviews, it might not be a bad idea to check it a little bit more frequently, especially for owners out there running increased boost on their EcoBoost. But now we wanna talk a little bit more about the installation as promised earlier. And, again, very simple stuff here, one out of three wrenches on the difficulty meter. Sites actually gonna call this 10 minutes which I think might be pushing it a little bit. There is a small amount of work involved to get to remove that factory hose which really isn't hard, but then you have to mount the bracket, mount the actual canister and then plug everything in. Now, to give you a better idea of how that all goes together here's our detailed walk-through along with a quick tool breakdown.Man: Tools needed for this install are 1/4-inch ratchet, 3/8 socket, 7/16 wrench, and a Phillips head screwdriver. So, the first step of this install is gonna be to remove the PCV fitting behind the throttle body underneath the intake manifold located right here. All right, so next, we have to disconnect this side of the PCV fitting right above the starter, underneath the intake manifold against the block. It's a little tricky to get it, so I'm going from the underside. Now, make sure when you install this onto your engine that you put the line leading from the filtered side connected to the block and the other connected to the intake manifold. All right, now we can place our oil separator into the engine bay. I'm just gonna use the lines clipped to the fittings to hold it in place until I can use the bracket supplied in the kit. I'm just gonna pass the engine side tube down to the fitting on the bottom half of the block and I'll reconnect that once I have everything in place.Now, I'm gonna use the provided bracket and hardware and I'm gonna mount the bracket to the strut tower. Now, we can make our final connection back here on the bottom of the block. Now, I'm gonna take a 3/8 socket, and a 7/16 wrench and tighten up my bracket.That's gonna wrap up this review and install of the JLT 3.0 Oil Separator for the driver side of your '15 to '20 Mustang EcoBoost. Thanks for watching and, for all things Mustang, keep it right here at

      Reduces Engine Sludge. When venting crankcase exhaust back through your intake track, large amounts of oil vapor comes along as well. This can dilute your gas and lower its octane level. Combat this by installing a Satin Anodized JLT Version 3.0 Oil Separator, which can filter out the oil vapors and turn it back into a liquid. This driver side separator is designed to collect even the finest crankcase exhaust vapor and dropping it into the easily removable bottom tank, all while allowing clean air to pass into the intake.

      Version 3.0. JLT improved on the designed of their previous Oil Separator with the introduction of their new and improved Version 3.0. The first big change you will notice is the larger 3 ounce capacity, almost double that of their previous model. Another important difference is the filter media. Older JLT Separators used a Ford Motorcraft pre-filter, but now JLT uses a 1/2" thick 1/16th" aluminum honeycomb filter with a mesh stainless steel screen to trap even more fine oil vapors than before, preventing them from gumming up your engine.

      Superior Quality. This JLT Performance Air/Oil Separator is proudly manufactured right here in the USA. JLT CNC-machines their satin separator from a solid block of billet aluminum for superior strength. Designed with a rubber O-ring, this Oil Separator will maintain a tight leak-free seal. The base features a knurled texture, so that it can easily be gripped for removal during routine oil changes. JLT then completes their Catch Can in a durable clear anodized satin finish for aggressive good looks and long lasting corrosion resistance.

      Easy Installation. JLT Performance engineered their Oil Separator to be installed in under 10 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.

      Application. This JLT Performance Version 3.0 Satin Driver Side Air/Oil Separator is designed for use on 2015-2021 EcoBoost models. Installs on the driver side, same side as the PCV valve.

      Technical Note. This JLT Air/Oil Separator is not CARB certified, therefore it is not legal for use in California or other states adopting California emission standards. It is intended for off-road use only.
