      Video Review & Installation

      The JLT V3 Oil Separator is a catch can setup with even more holding capabilities than previously offered through JLT, and it plugs into the intake tract. And it's a great way to protect an engine. It's a simple mod that does some good for all applications. You don't need to have a forced induction set-up to be able to utilize a catch can, but in the case of the turbocharged EcoBoost, it's especially important. A catch can might not be one of the first mods that's on your list or may not even be on your list at all, but it's a very functional piece that has benefits to it and it can do good for even a completely stock motor. I'll talk more about the install later, but I'm gonna call this one a one-out-of-three wrenches in the difficulty meter. So if we go back to the process of an internal combustion engine for a second, I can explain the benefits of an oil catch can like this one here. So the ignition of the air and fuel mixture inside of the combustion chamber is ignited and it forces the piston downwards. There is a small amount of mixture that leaks past the piston rings and into the crankcase. This is known as blow-by. And in that blow-by, there's an oil mist. The blow-by and oil mist will settle in the intake and over time they're gonna form a gunky build-up. Now, technically speaking, there can also sometimes be condensation along with the oil mist and the blow-by. And if you let all this hang out, or worst case this stuff can make into the oil inside of the crankcase. This is not a good thing and it's considered oil contamination and dilution. So you've got your PCV valve to help fight this issue. A PCV valve alone has its own list of weaknesses, and engines have regulations as far as emissions go. So the current set-up as far crankcase ventilation systems means an engine will have detonation or knock when oil is in the combustion chamber. If the knock sensors pick this up, they're gonna pull timing and that's never a good thing. Another thing that happens is carbon build-up on the piston tops and the valves as well. Enter into the scene the oil separating catch can. It's gonna push these gases, the blow-by and the oil misting condensation through a baffle system that's gonna trap the oil and separate it from the other gases. The gases are gonna be allowed to continue through the intake, so they can be burned off and the oil will stay inside the catch can, so it doesn't move on and cause issues for the engine. So this is a single can that mounts on the driver's side of the EcoBoost on the strut tower. Inside, there's a new multi-stage filter that's going to separate the oil from the air and the other gases. The filtering process consists of a fine mesh screen which then passes oil vapors through an aluminum honeycomb filter. The can itself can hold three ounces of fluid, and you'll notice that the better catch cans actually catch pretty much oil. So the larger capacity of this can means that you won't be having to empty it all the time, go a little bit longer between servicing. And the bottom of this can just unscrews when you wanna empty it. It's sealed with o-rings, so it won't leak at all. The kit is gonna include everything that you need for the install here. You have your mounting brackets, so you can mount this. And it's gonna be positioned, so the can is in an easily accessible area. So when you do need to empty it, it isn't gonna be a fight. It's also gonna come with direct-fit silicon hoses that have some pre-installed stock style quick disconnect fittings which make the install easy. It'll be completely plug-and-play. It doesn't get any more straightforward than this. And the can itself is a billed aluminum can that's sealed, like I mentioned earlier, and, of course, powder coated black. As far as price, you're looking at spending between $100 and $200 for this catch can. Now one thing I will say about catch cans in general is to be wary. You wanna make sure that you're getting a good one that will trap as much oil as possible. Some catch cans are just empty container with a few ports, but these kinds are not gonna condense oil vapor and trap as much oil as possible. You wanna make sure that the catch can has an internal baffling collection system like this one does. So the install here is really pretty easy. You're looking at spending an hour tops and it's gonna be a one out of three wrenches in the difficulty meter. You just need some basic hand tools to get this all done, and I'd start by disconnecting your stock line form the PCV valve under the intake manifold on the engine block and behind the throttle body. You can wrap the hoses under the intake for the fitting that's right behind the throttle body, and the rear hose down towards the engine mount. All the hoses will just snap into place after you have them ran and that's all it's gonna take. Mount the separator assembly to the bracket getting your mounting bracket into place. Wrapping things up here, the JLT Oil catch can is a fast and easy way to protect the motor of the boosted S550 from blow-by. You can check it out more online right here at

      Reduces Engine Sludge. This JLT Version 3.0 Air/Oil Separator is designed to collect even the finest crankcase exhaust vapor and drop it into the easily removable bottom while allowing clean air to pass into the intake. When venting crankcase exhaust back through your intake track, large amounts of oil vapor come along as well. This may even dilute your gas and lower its octane level. The JLT Oil Separator combats this by filtering out the oil vapor and turning it back into liquid form.

      Version 3.0. JLT improved on the designed of their old Oil Separator with the introduction of their new and improved Version 3.0. The first big change you will notice is that the Version 3.0 Separator has a larger 3 oz capacity, that is 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 to prevent 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 Air/Oil Separator from a solid block of billet aluminum for superior strength. Designed with a rubber o-ring, this 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 black anodized finish for aggressive good looks and long lasting corrosion resistance.

      Easy Installation. JLT Performance engineered their 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 Black 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.
