JLT 3.0 Oil Separator

3oz Capacity
Solid billet construction.
OEM Style quick connect PCV fittings
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, intake tube, intake manifold runners and even dilute your gas, lowering its octane level. This happens on all engines and is even worse with forced inducted vehicles (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.

    Great product, easy to install. I can tell after 500 miles the truck runs better and smoother with a little extra game in MPG.

    I have JLT catch cans in all three of my vehicles. To include a used Silverado I just bought that had a cheaper brand already in it but I changed it out for a JLT… Love them

    Since the long term effects cant be measured due it being a recent install, I will address the install process. The factory hose is difficult to uninstall if you cant get your hands into small places. I installed mine at 50K miles, which made disconnecting the hose at both ends somewhat difficult. Once they were disconnected installing the JLT Catch Can was simple and easy. Just ensure that you hear the click when attached.

    JLT 3.0 Oil Separator

    Posted by Majestic Plum on Feb 19th 2021

    Super easy install on 2016 Escalade 6.2
    Works great, catches oil and a bit of condensate, I drain it about every other week and get a couple ounces combined. Glad it's not going into the motor.

    JLT 3.0 Oil Sepatator for a 2015 Silverado LT

    Posted by Shaden White on Feb 19th 2021

    I have only had it on for about a week but the speed in which I got it, the quality of the product, the packaging with the easy step by step instructions with pictures, and the fast/easy install made this a no brainer. Excited to see what other stuff you offer for my truck in the future!

    Purchased the JLT 3.0 and received it within 3 days. The build quality is amazing and the ease of installation is great! Already saw results of it working within the first day of use. The black perfectly matches everything and the material is great! Definitely recommend this oil separator to anyone with a Ecotec Silverado
