Description
Reduce Sludge. In your Mustang's engine, crankcase exhaust is re-circulated back through your PCV system and intake, taking with it large amounts of oil vapors. This JLT Oil Separator kit installs in your PCV line to filter out oil before it can get into your engine's intake - where it doesn't belong - and cause damage.

Premium Quality Kit. This high quality kit includes the JLT Oil Separator, which features billet aluminum construction with a black anodized finish for superior style and durability. The 2 oz. tank base is easily removed for draining during oil changes, and is designed with a o-ring for a leak-free seal. Plus, JLT added a Ford Motorcraft metal mesh PCV pre-filter to prevent any oil from getting back into your intake.

Easy Installation. This complete kit includes a factory PCV line that has already been modified with the necessary fittings and attached to the separator for a true plug-and-play installation.

Application. This JLT Oil Separator kit is designed for the 2011 to 2015 GT and BOSS Mustangs. Designed for direct installation on the passenger's side only (same side as the PCV valve).

Technical Note. There is a unique JLT separator kit recommended for 2007-2014 Mustang GT500's - click here.

JLT Oil separator

As usual, fast shipping from AM! Overall I'm impressed with the quality of the can and filter. This separator was also the easiest installation I have ever done on a car - literally 30 seconds and done.

Installed with supercharger Does it come with fittings to install in a straight line on the valve cover? I have the roush supercharger. I see someone has it installed on the customer photos but not sure if they had to get the fittings themselves?

Intake Air This prevents oil from entering the intake, but the oil fumes are mixed with the air and fuel which makes the air and fuel intake impure. You need a vacuum system like the old days using the exhaust for removing the back pressure.

  • Not so, as the crankcase oil/air mixture enters the separator it passes through a fine screen the oil sticks to the screen, and after enough of it builds up it drips down to the bottom of the separator. The intake creates it's own vacuum to make this happen. I only have 1256 miles on my GT, I haven't collected much oil on the drivers side separator, but at least two or three tablespoons have been separated on the passenger side.

    JLT Oil separator

    As usual, fast shipping from AM! Overall I'm impressed with the quality of the can and filter. This separator was also the easiest installation I have ever done on a car - literally 30 seconds and done. In my opinion though, it is a little overpriced, but I see it as an investment in my engine for the long term. I hope to have this 5.0 for a looooong time.... **There are JLT separators for both the drivers and passengers side of the engine. If you're only planning on getting one, get the passenger's side. That's where a majority of the oil passes through before heading back into the intake.**

    This product might shock you

    When I installed the JLT sperator I was expecting a great product the worked well at keeping the oil out of the intake. What I got was a beautiful looking oil sperator that perfectly and litteraly plugs right in and after a week of normal driving shocked me with just how much oil it keeps out of my 5.0. I recommend this product as a MUST have for anyone no matter how you drive your car this will be a purchase you never question. One look after an oil change interval will convince you and anyone else who doubts how effective this seperator is, and the looks will always make you smile.

    Boss Fitment Issue

    I received my order from AM in 2 days from the date I ordered... Excelent shipping as usual. When I installed the JLTOSP-FMG11-B JLT Oil Separator (PS) the can hits the coolant tank and the knurled part marred the plastic on it. What I did, which was no big deal was cut the tube on the valve cover side 2" shorter and re-clamped it with a 365 deg. #17 ss Oetiker clamp which centered the can between the coolant tank the the front of the engine. (I downloaded photos which I'm assuming AM will post) Other than that the product is high quality and based on what I've been told should resolve unwanted oil getting into the intake manifold.

    No question, it's nice and easy.

    Didn't have a single problem installing this, and it looks great. Literally took less than 5 minutes. Accidently ordered 2 and AM took the second one back without any problems or questions. I have bought over 90% of my parts for my 2011 5.0L from AM and I plan on buying TONS more. Thanks AM!

    very nice and compact

    the JLT seperator is a nice product. it seems to be built very well, and it came with everything needed to plug and play. very quick and easy install. i think it is priced pertty competively, you get a good name brand for the price. and now days it is pretty much about the money. i am very pleased with American Muscle and JLT.

    Protects your engine

    Purchased this and installed on my 2013 GT passenger side stock mustang. Noticed significant amount of oil in the can after only 100 or so miles. Surprised that Ford doesn't put these on the car stock to prevent detonation. Was able to easily change one fitting and make it work after I installed my supercharger. Highly recommend this product!

    Oil separator

    Works great. Installed and drove 250 miles and it caught almost a teaspoon of oil. I was pleasantly surprised knowing that my money was well spent. Ordered another one for my Mach 1 too. Always fair prices and fast shipping at American Muscle! Thanks AM.
