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 Driver Side Oil Separator kit is for use on the 1999 to 2004 GT and Bullitt Mustangs. Designed for direct installation on the driver's side only.

This is a must for any car.

The JLT oil separator is well worth the money, solid construction and great fit. With the amount of oil that collects in the holding container, I wish I would have gotten one sooner.

Question about the filter Is the inline filter a lifetime filter or is it serviceable?

  • You can clean the metal mesh screen if needed. But I doubt if you would need to do this often, if at all. When you empty the seperator, you can inspect the mesh at that time. Good luck.

  • This oil separator works in conjunction with your PCV valve. It is not meant to replace your PCV valve. The separator prevents oil mist from entering your intake system and is one of the first mods that should be installed on any Mustang. Good luck.

    JLT Oil Separator

    I purchased this with the passenger side separator. It's a little more difficult to install than the passenger as you need to drill two little holes at the fire wall to mount the bracket. It comes with plenty of hose and adapters to custom fit your specific application. Just make sure to mount it in an area where you will easily be able to unscrew the catch can to drain it. It also maintains a stock look like they came with the car; very cool!

    Simple installation, great twist off design, quality product

    Just installed and the JLT oil separator is a well designed quality product. The black anodized looks great under the hood, it almost appears stock. I prefer this twist off style compared to drain valve because it is very easy to clean. I do recommend cleaning the catch can during every oil change to avoid build up. I got my stang with 56k miles and now it has 70k miles and I don't know why I didn't order this product sooner. I'm very happy with this oil separator and if your considering getting one do it because I know you will be happy too! The only downside to this product is... umm... I can't think of one. Great product JLT!!

    Review from JLT Black Oil Separator - Passenger Side (99-04 GT, Bullitt)

    Simple Oil Separator

    I purchased this Passenger Oil Separator with the Drivers side. Both went in easy. The kit comes with plenty of adapters and hose so you can custom fit it to your specific application. Check the box for all of your parts first. I was missing the mounting bracket but the AM team contacted JLT and they shipped one out ASAP. Love these guys! And love my JLT Oil Separator!

    Oil Separators Work

    I installed 2 on my mustang and after a hard work out all day I checked and found a small amount of oil that wound have gone into intake and caused spark plug fouling or build up on the intake values.
