    Eliminates Engine Sludge. Install the JLT 3.0 Black Oil Separator today to achieve sustained maximum engine performance from your Mustang. This separator prevents blow-by from circulating back into your PCV system where it can gum the engine, coat the inside of the intake manifold and the throttle body and rob you of your engine power and performance.

    Improved Version 3.0. As an improvement to the preceding model, this version features a larger 3 oz capacity of fluid retention – double capacity. It also uses the more efficient 1/2" thick 1/16” aluminum honeycomb filter with a mesh stainless steel screen that traps finer oil vapors more effectively.

    Durable Construction. Made from CNC machined solid billet aluminum, the JLT Version 3.0 Black Oil Separator features a rubber O-ring to provide a tight, leak-free seal. Additionally, oil change is made easy with the knurled bottom for easy removal. It is completed with a corrosion resistant aggressive-looking black anodized finish for durability.

    Installation. Comes as a complete kit containing two PCV lines with easy quick-disconnect fittings that facilitate a plug-and-play installation in 10 minutes with no modifications.

    Warranty. JLT provides a limited lifetime warranty on this Black Oil Separator against material and craftsmanship flaws.

    Not CARB Certified. This Oil Separator is not legal in California and states with similar emission policies.

    Application. JLT Version 3.0 Black Oil Separator is compatible with 2011-2017 GT, 2012-2013 BOSS and 2015-2017 GT350 Mustangs.

    So this comes in either drivers or passengers side, if you install one on one side, why would you not install one on the other side? Seems short sighted to only install on one head, right? To me install on both sides or not at all. ??? If I don't understand something please educate me. Thanks.

    • The JLT V3.0 Black Oil Separator is available for either side, and both can be installed together. This is offered as either side, as the majority of oil pulled into the PCV system on the 5.0L comes from the passenger side, however some people prefer to install on both sides.

      Does the job but be careful

      On my 2017 Performance Pack GT, The catch can itself is totally fine, the hose routing and bracket however are a joke. If you have a factory setup intake, you simply cannot install it properly. The noise tube is the main bulk of the issues, however on the performance pack my strut tower brace really got in the way too. So much so infact that while I was attempting to get everything together, the bracket slipped and left a nasty gash on both my strut tower and strut tower brace. All in all I'm not upset with the quality of the product itself, but take care with a stock intake system.

      Please Buy If you love your mustang

      For us folk that care about keeping the inside of the engine a little cleaner. Air at 8,000 rpm's is turbulent and oil can and will be blown so let the JLT catch can help you. super easy install super easy to maintain!

      It’s alrighhr but will get the job done for sure

      It was a little difficult to install. Took me like 20 minutes. I don’t think it’s really designed to be next to the stalk intake with the noise tube still attached. If your getting this with the stalk intake, definitely get rid of the noise tube and it’ll fit but it’ll be very snug. Once I get rid of the noise tube it will be looking good.

      Could be better

      First off this is a must have along with the passenger side kit. That being said, the passenger side install was a piece of cake. The driver side however is another matter. The directions are kind of foggy. After looking at a couple of pictures I could make out where the bracket went and fitment of the bracket. The only reason I did not give this 5 stars is the hose shape design. The fit is very unnatural and feels like it’s binding. It also hampers removal of the tank SLIGHTLY, because as I said the hose going to the valve cover is binding against the catch tank. I tried several different positions and could only get this position. Also, trying to remove the hose from the valve cover proved quite difficult, as the clip would not disengage. For my money fitment should be precise. All in all a great product. But the hose shape definitely needs improvement.

      Why not

      Just to be extra sure that oil is staying out of the intake. It catches very little.

      Great fit and finish

      Also have the passenger side, this one takes a little longer to install. Just note it mounts to where the sound time goes. I did the sound tube delete at the same time so it worked out well. Seems like a solid product, no issues so far.
