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 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 2017 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.

Pass vs Driver side? 2008 Roush Could I get just one for the pass. side be ok or do I need to get one for both side? which one gets more oil? Thanks

BlackJack36

  • If you're only wanting to purchase one side, go with the Passenger Side as that collects more oil than the Driver side. Having both will only help to ensure both sides are protected, but you certainly can install the one side and be much better off than having neither installed! Hope this helps!

Is this a 2-chamber system?

A

  • This has an entry chamber that opens to the reservoir and then an opposite metal mesh filter side. So, in that aspect, it is a 2 chamber set up. Works very well! Definitely worth it!

Cleaning? Does this need to be cleaned out, I assume? If so, how often?

rwwagner90

  • Yes it needs to be emptied of oil accumulated. How often will depend on the car and how much is accumulated. I would suggest every two weeks to see and then go from there based on how much is in there As far as cleaning just dump out the oil. Do not add it back to the car as there is often moisture in it.

    Must Have for Coyote Owners

    This is a must have mod for coyote owners. I am amazed every time I check it at out how much oil it prevented from returning into the PCV system. Simple to install, but it has a big impact on the longevity of your motor

    It was so easy to just disconnect the stock piece and install the JLT in 2 minutes. Well worth it knowing the excess oil will not go any further than the separator.

    Best investment for your engine...

    I have a JLT oil separator on my 2014 mustang, and it is amazing how much oil this collects. I don't want all that oil going into my new 2017 5.0, so I had no problem ordering this for my new Mustang (before the car even arrived)!!! GET IT you will be amazed at how much oil will NOT be going into your intake. Note: I have to select a 2016 Mustang from the available years since AM has not listed the 2017 yet.

    It works!!!

    So after only 400 k I have collected 1 teaspoon of oil that would have been sent into the combustion. That is pretty crazy. This thing deffently works! This is kind of alarming as to why so much is collected. It's a must have as there seems to be a lot of oil these bad boys save from clocking up the combustion chambers, spark plugs and whatnot... Will be worth the money!

    works great

    i knew these would deff help with stoping oil from getting into the intake system and manifold. but i didnt know they would work so great. it literally stops ALL OIL i have already unscrewed them and poured the oil right back into the engine, it seems like the pass side one gets more oil then drivers side, dont know why that is. but these FIT AND WORK GREAT. they are amazing.

    Took under a minute to install, so easy, quality of product is great, just checked it after 300 miles of driving and there was already a small amount of oil collected (teaspoon of oil) glad to know my intake will stay cleaner in the long run and I'll be sure to empty the oil separator every oil change.
