      Reduces Engine Sludge. Stop engine sludge from hampering the power and performance of your 4.6L V8 Mustang. Installing a JLT Version 3.0 Air/Oil Separator will prevent crankcase exhaust, better known as blow-by (an oily vapor), from re-circulated back through your PCV system and intake. If left unchecked this oily vapor can solidify becoming engine sludge. This nasty sludge can coat the inside of your throttle body and intake manifold robbing you of power. A JLT 3.0 Separator is an ideal upgrade for all 1999-2004 GT Mustangs that want to reduce engine sludge in order to maintain power and performance.

      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 Passenger Side Air/Oil Separator is designed for use on 1999-2004 GT and 2001 Bullitt models. Installs on the passenger 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.

        Quality piece

        Does its job and works really well. Getting about a tablespoon of oil every 800 miles. Otherwise that would be gunk in my engine. My car is N/A for now and still works great.

        Short hoses

        It works as it should but the hose supplied with it were way to short so I had to go buy new hoses

        Oil separator for 2v new edge mustang

        Great product that takes a very little of your time to install. I have a 02 2v mustang GT n/a motor. After driving 1000 miles I checked the can and it had accumulated some oil. If you boost your gt your going to want it anyway. I think its great for both boosted and n/a applications. I love the mounting bracket it comes with. The black goes along with stock look in your engine bay.

        4 2001 Bullitt - HollowPoint

        Good quality product

        I haven't had a chance to really see if this product works yet but it was fairly easy to install, took about 45 minutes. The directions weren't very clear but I was able to figure it out without them, this product is pretty self explanatory.

        5 2002 GT - BenG

        Works Great

        This oil separater is very easy to install. It is literally just a couple hoses, a bolt, and two screws. As previous reviews have said its really cool to see the oil that would have been burnt through the engine. Its cool to have something installed that you can see the results right in front of you.

        Catch Can review

        Installed this on an 01 Bullitt. Fit perfect and solved the chronic pinging issue due to oil contamination.

        Thumbs up!

        As a Machinist the build quality is good. Maybe it should have baffles inside, I don't know. Only a little mileage on it so far and don't drive my 02 GT much. Enjoy!

        Awesome product

        I purchased and installed this oil separator on my GT after doing a headjob, and I must say it did exactly what it was suppose to, keep the blow oil from getting into the intake. After a few hundred miles, checkedit out and found about an ounce of oil in it. My car is N.A. and I would highly recommend it to anyone. 2 thumbs up. Excellent product!!!!

      Would you need 2, one for passenger side and one driver side?

      • Oil separators do not need to be installed on both sides.
