Review & Install Video

Hi I’m Justin with AmericanMuscle.com, here with a way to keep your Coyote motor clean, and sludge free, thanks to these JLT oil separators available in a black, or satin finish for all 2011 and newer Mustang GTs. So what do these do? Well, just about every internal combustion engine has what’s called PCV, or Positive Crank Case Ventilation. Basically what this does, is allows the oily vapors and gases that are produced during combustion, to escape the block or crank case in a controlled manner. A lot of times these oils and gases are routed through a PCV valve or a breather tube, back into the intake track to eventually be burned off by your engine. The only problem with this is these vapors can eventually dirty up the intake manifold over time and in some very extreme cases can cause damage, or lower your octane rating by diluting your fuel. This becomes even more of an issue on supercharged or turbocharged cars, where crank case pressures are increased, causing even more of this oily by product to occur. That’s where these oil separators from JLT come into play, these mount in line with your Mustang’s PCV system to catch any excess oil vapors or sludge. As a matter of fact, we did install one of these on our 2011 GT here a little while back, and since then we’ve been doing some spirited driving, and a few Dyno pulls, probably totaling 50-60 miles. Let’s take a look inside and see what we’ve collected. Alright, well there you go, that would have otherwise ended up back into our intake manifold. Taking a closer look at the kit, you’ll notice it’s actually pretty simple. JLT uses a 2 ounce, Billet aluminum collector, that’s available in your choice or either a satin silver, or a black finish, They also include these two preinstalled factory hoses, making this a completely easy plug and play install that should take you no more than 30 minutes. All you need to do is remove your factory tube connected your valve to the intake manifold, and plug the new JLT setup in its place. You will notice there are two PCV hoses on your Coyote motor, one on the passenger side and one on the driver side, does this mean you need to run two oil separators? Well, JLT claims that 80% of the oil and sludge on the Coyote motor comes from one side. Of course running one for each side would be the best option, especially if you’re running a boosted setup, but that’s for you to decide. So if you want to invest in a product that will help keep your Coyote motor free from sludge, then going with a product like this JLT oil separator would be a great place to start.

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 installed fittings, 2' of 3/8 NPT hose, extension fitting, angled mounting bracket, and 4 stainless mounting screws for an easy, hassle-free installation.

Application. This JLT Oil Separator kit is designed for 1996 to 2004 SVT Cobras. Designed for direct installation on the driver's side only (same side as the PCV valve).

Technical note. Compatible with the JLT pre-filter (on passenger's side) with the oil separator on the driver's side.

What is the "slight modification" required for a GT? I have a 02 GT, the fitment mentions that this product will fit the non-cobra models with slight modification. What would be the "slight modification"?

  • Minor modification in regards to attachment. The install guide on the Installation Tab actually shows you the instructions for both Cobra and non-Cobra models so that will outline everything for you! It's a very simple process and you shouldn't have any difficulty! Let us know if you still have any further questions!

    Good

    This product works great. I was burning a little bit of oil before this product. now this allows me to dump the extra oil instead of pushing it back through and burning it

    If this product performs as well as it looks there should be no future pcv issues once installed.The design is high grade and not a cheap one at that.

    I didn't realize how much oil my engine was sucking up until I installed the JLT separator. Now I have the peace of mind knowing all that nasty oil is in the catch can only!

    Great product

    The JLT oil seperator is a very nice product and easy to install. I will be installing the JLT prefilter soon on the right valve cover. Its very nice knowing that only clean air is venting through the intake sytem now.

    Great product

    This seperator does what it says, and everything just fit perfect. Seriously for the time it would take to build one and find a location for it makes this is well worth the price! However the only downfall is that there is no drain valve. You have to unscrew the can to drain it. For that reason it received 4 out of 5. Call me lazy, but it's true.

    That's no good

    Fitment was a little tricky, still need the right size step down adapter since its not a cobra. 1/4 in of sludge per week in it. Worth the buy if you want to keep your t/b and intake manifold clean of oil.

    A must have for03-04 cobra owners

    This oil separator does exactly what it's supposed to do and looks good while doing it, installation wasn't too difficult and they're is enough supplied hose incase you make a mistake cutting to try again. I had my 2004 cobra out last Sunday and I drove her pretty hard for about 40 miles there and back. Needless to say I checked my separator and there was a tiny puddle in the bottom that I now never have to worry about being sucked into my motor. If you have a forced induction mod - motor this is a must.

    Does it work?

    Yes it does work. I have an 04 Cobra with 11,000 mi. I just finished a 600 mile wine tour with our car club and checked to see what was collected. I was surprised to find what I did in the canister. The trip included some spirited driving on some back country roads in central Calif. So it prevented all that oil from reaching the intake manifold. I'm glad I installed it before the trip.

    JLT Oil Separator - Great Product

    Very high quality product & easy install. Although my 18K mile 03 Cobra doesn't show any visible signs of burning oil (no smokescreen or noticeable oil consumption) there must be some blow-by, so I installed this as a preventative. I don't want oil coating the intercooler reducing its charge cooling efficiency, or oil being forced into the combustion chamber. There is one additional step (not mentioned in the instructions) which I recommend for anyone doing this install. The plastic hose nipple on the side of the of the oil separator with the hose which connects directly to the PCV valve has a hole drilled through the threaded portion of the nipple. That hole lines up with an internal hole in the top part of the oil separator. There were quite a few fragments of plastic from the factory drilling through the threads of that hose nipple. I removed the plastic hose nipples, disassembled the oil separator, trimmed off the attached plastic drilling fragments, & cleaned everything up before reassembling it for installation. Those plastic fragments probably would not have made it through the JLT filter and into the engine, but why take a chance???
