JLT 3.0 Oil Separator

3oz Capacity
Solid billet construction.
Multi stage filter system designed to collect the finest of vapors and drop them into the easily removable bottom while allowing clean air to pass through to the intake.

How does it work?

During the process of venting crankcase pressure back through your intake track, large amounts of oil in the form of vapors can coat your blower rotors, intake valves, intercooler fins, and even dilute your gas lowering its octane level. This happens on all engines and is even worse when supercharged and turbocharged as crankcase pressures are increased. To combat this, we have developed an oil separator of our own design. Milled from solid billet aluminum this is a rock-solid piece. It has a knurled tank base for easy removal to drain the spent oil and an O-ring seal to prevent any leaks. 

Filtering consists of a fine mesh stainless steel screen that traps fine oil vapors and releases them once heavy enough to fall. They then pass through a 1/2" thick 1/16th" aluminum honeycomb filter where they grow every larger and then fall into the bottom. By the time the oil gets through the filter it's too heavy to be passed on into the intake. The tank holds 3 oz of fluid, while that may not sound like a lot, you shouldn’t see that much oil in your PCV system. Drain it every 2000-3000 miles and you will never come close to filling it.

Our kits are easy install, service and flat out work! Many kits use OEM hoses or come complete with all hoses, custom brackets and hardware for an OEM look. Retain stock hose if you ever return to stock.

    3.0 oli separator

    Posted by Tom on Jul 18th 2021

    Just installed on my 2019 4runner. Drove 3100 miles on a road trip in some hot weather from WA. To Az and back. The container had approximately 1 1/2 Oz of dark oil in it. I changed the oil right before we left. I was shocked at how much oil was in the container, sure wouldn't want it going back to the intake. Great product, does what it's made for! If your on the fence about it, don't be, buy it! Thanks JLT!

    JLT 3.0 oil separator for 2011 Toyota 4Runner Trail

    Great product! I had one of these on a 2016 Mustang and was absolutely amazed at the amount of oil it keeps out of the intake system. This one for my 4Runner came with all of the hoses, fittings and mounting bracket with screws. Everything fits perfectly. No trimming or cutting the only thing I needed to do was position the bracket and canister so you would not get a “hard hit” when re-installing the engine cover. The instructions were spot on and the little tip of using a small amount of grease on the hoses and fittings made installation a breeze. A lot of aftermarket parts need a little “massaging” to get them to fit properly. I’ve been turning wrenches now for over 60 years and have never had anything like this that was so easy to install and fit so perfectly.
    Cudos to JLT for their engineering and expertise . You can definitely buy their product with confidence that it will fit and function perfectly.
    Thank you JLT……

    JLT oil separator 3.0/Toyota 4.0l V6

    Works great, does exactly as they advertise, the 2010 4Runner install was super easy, the 2015 Tacoma, install was easy too, I do run a wix oil filter, maybe taller than oem, not sure, but the separator sits right on top of the filter, actually touching the filter, as of right now no discoloration on either the filter or the canister, but would buy again l, just food f/thought
