      Video Review & Installation

      Justin: The J&L 3.0 Driver Side Oil Separator that we're talking about here today is gonna be for the 2014 through 2018 V8 Silverado or Sierra owner who is looking for the ultimate protection in regards to capturing the oily vapors produced during combustion from being rerouted back in your truck's intake tract gumming up the engine in the process. Now, the J&L will feature that billet aluminum 3-ounce container here in black complete with factory-style hoses and fittings, all for right around that high $100 price point.Install is gonna be a plug-and-play job here, gang. So, figure a solid one out of three wrenches on the difficulty meter, maybe an hour if not less to get everything knocked out from start to finish. And if you hang with me for a bit, we'll walk you through that job later in the video. So, if you guys didn't know, your truck has what is called a PCV system or positive crankcase ventilation. Now, the purpose of this system is to regulate and remove the fumes produced during combustion from the engine crankcase to help alleviate that crankcase pressure, which could otherwise lead to things like oil leaks or seal damage.Now, because laws do mandate that the PCV system be sealed, the engine has to use vacuum to draw these vapors out of the crankcase and then plug them back into the intake tract where they are to be burned off during the next combustion cycle. And while this all sounds good in theory, and yes, this is pretty much what happens, oftentimes these oily vapors end up leaving residue in your intake manifold and even on the backside of your intake valves, which can lead to things like valve coking or deposit buildups over the years.Now, just to clarify again, this is the driver's side that we're talking about here today. I would argue the passenger's side typically is gonna do most of your heavy lifting in regards to being the more productive side, if you will. And hey, if you haven't already considered or installed a passenger's side separator, you can also check one of those out here on the site from J&L or maybe somebody else. Now, I would argue here the driver side is going to be a great addition or a great complement to that passenger side option and would equate to basically the ultimate in protection with both installed for both your 6.2 or your 5.3-powered ride.But with all that out of the way, how does this little guy from J&L do its thing? Well, basically, that oily vapor is going to pass through the PCV system of your truck and then into the J&L separator. Now, at that point, the solids present in this vapor, basically those little tiny microscopic particles of oil and unburned fuel and other crap get caught up in the aluminum honeycomb and stainless steel mesh material at the top of the separator and then basically isolates it and collects it down in the canister below while still allowing fresh clean air to pass through the PCV system.Now, as far as emptying this guy is concerned, well, that little neural bottom here helps you unscrew things. J&L claims every 5,000 to 7,000 miles is probably your best practice. But my experience with having these installed on my own personal trucks every 1,000 to 2,000 miles is not a bad idea because you might be surprised just how quickly these little guys can fill up.Now, when it does come time to empty everything out, just do so responsibly. Don't pour them down the drain or in the yard or anything crazy like that. And, as always guys, read up on the numerous four and five-star reviews back on the product page if you haven't done so already on the J&L formerly known as JLT. A lot of good feedback from fellow 6.2 and 5.3 owners about running these on their rigs. It's a good way to get some real-world feedback.Now, as far as your construction is concerned, well, very nice build here with the J&L starting with that neural billet aluminum canister we just talked about. Three ounces is your capacity here. We got a laser-etched logo right up top on the canister itself along with your included bracket. This particular option does feature that stealthy black finish. Kind of disappears under the hood a little bit more. But if you're the type of truck owner who prefers maybe a little bit more flash under the hood, J&L does also offer their satin silver version that you can find here on the site instead.Now, one of the big pros for me with the J&L kits is that they do include the factory-style fittings and hoses cut the link for you, which in turn will make for a very easy install, but also a factory-like fit and finish. Speaking of getting everything installed, guys, let's switch gears and touch on that install a little bit more here. Plug-and-play job for the most part. Again, you do have to mount the bracket itself for the canister. J&L does include all of your location's hardware, all that good stuff, which will make this a very simple job. But to give you a better idea of just how easy things will be in the garage or driveway, feel free to check out our detailed walkthrough and tool breakdown now.Man: Tools used for this installation, Phillips screwdriver, 13-millimeter socket, 5/16 sockets, 1/4-inch drive ratchet, and 1/4-inch drive extension.Hey, guys. I'm gonna walk you through the install of our J&L oil separator on our 2014 Chevy here. First thing we're going to do is remove our airbox. So, let's get started. So, to uninstall our airbox, first thing we're gonna do is push up on these buttons here and pull our lines off our airbox here. And we've got one over here, same thing. You're gonna push on to the clip. And once you push the clip, you'll hear a pop, and then you can slide these out of the way.Next, I'm gonna take a 5/16, I'm gonna get in here, loosen up our clamp off our throttle body, and one over here that hooks up to the airbox over here. Now, once I get those two loose, we're just gonna give it a snug, pull it off there, pull it off there, and that removes our airbox. So, now we're gonna remove our PCV line, which is gonna be a little difficult to see once you have a connection back here and a connection down underneath the throttle body. You're gonna push in the white tab on the connector and then pull up and it will release.And once you do that, you're gonna be able to spin this. And once you spin it, it'll give you access to the white tab on the back here. You're gonna push that in and feel it click, and then pull it out, and then fish it right out. It is a little tough to get to the back one, and you just got to make sure that you push that tab down. Once you turn it, it gives you better access to the tab.Now that we have this removed, we'll start installing our oil catch cans. So, now to start our install, we're going to remove this 13-millimeter right here. This is where we're gonna install our bracket. I'm gonna take my bracket, install it, just like that. Now, I'm just gonna snug it, I'm not gonna make it tight yet, so we can move it around. We're gonna take our catch can with our two Phillips screws that they supplied. And you're gonna wanna line the C up with the C on this. So, this writing goes just like this. And then we'll start one of our screws. And now start the other one.Once we get those two started, I'm gonna take my Phillips screwdriver. And we'll tighten them up, just like that. I'm gonna move it somewhere right around there to start with. And now we'll start getting ready to install our lines. So, now we're gonna install our lines. You're gonna wanna look inside your lines, you're gonna see there's some O-rings in here. I actually put a little oil inside there to help lubricate the O-rings. I also put some oil onto both of the fittings. It's gonna help when this slides on.So, what we're gonna do is we're gonna take the outer one here that's closest to the 13-millimeter on this side, and we're gonna route that down through here. And then this is gonna go and connect down to our bottom line pretty much like that. You wanna take this one and route it down through here and fish it so we can hook it on to our line down here. I'm gonna push that one on. And that's good. And then what we'll do now is we will adjust our canister where we want it and tighten that 13-millimeter up.I'm gonna put my canister back here a little bit just like that. Take my 13-millimeter, give it a good tight. Now we're gonna install airbox. Now we're gonna take our airbox and reinstall it. I'm gonna start by getting it in place. I'm just doing it on the throttle body, pushing it on, sliding our foot on over here. Once we get those two in place, I will reinstall our connector there and our other hose on this side. Take my 5/16, tighten up our two hose clamps.That wraps up this review and install of our J&L 3.0 Black Oil Separator Driver Side for '14 to '18 V8 Silverado and Sierra 1500s. Thanks for watching. And for all things Silverado, keep it right here at

      Keep Your Engine Running Perfectly. As beneficial as your Silverado 1500’s positive crankcase ventilator (PCV) valving system is to your engine, it isn’t without its drawback. When crankcase pressure is vented back into your intake, vaporized oil is often included in the mix. This oil vapor can accumulate over time becoming harmful engine sludge. The J&L V3.0 Driver Side Black Oil Separator helps mitigate this problem by catching these oil vapors and collecting them in a sealed catch can. This ensures your fuel’s octane levels remain undiluted, and your truck performs optimally.

      Unique Design. The J&L V3.0 Driver Side Black Oil Separator features a unique filtration system consisting of a fine stainless steel mesh that traps oil vapors and releases them once oil gets too heavy. The oil then proceeds to a second component made from honeycomb aluminum, where it’s condensed further till it settles to the bottom of the catch can. This catch can’s 3-ounce capacity is good 3,000 miles before it needs to be emptied.

      Robust Aluminum Build Quality. The J&L V3.0 Driver Side Black Oil Separator is CNC-milled from billet aluminum for strength, minus the weight. A rubber O-ring prevents leakage, while a knurled base makes opening the catch can easy, even when oily. Finally, this oil separator receives a durable, black anodized finish for maximum corrosion resistance.

      Convenient, No-Mod Installation. The J&L V3.0 Driver Side Black Oil Separator installs directly on preexisting locations on your truck and requires no modifications. This oil separator comes with hoses that use a push-lock system for easy installation without the need for clamps. Also, this assembly installs using just standard hand tools.

      Comes with a 1-Year Limited Warranty. The J&L V3.0 Driver Side Black Oil Separator comes with a 1-year limited warranty covering workmanship defects. Please visit the manufacturer’s website for more details.
