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.

    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

    JLT 3.0 oil separator for 6.2 Sierra

    Posted by DJ on Apr 16th 2020

    First and foremost the customer service was outstanding. The product looks amazing and I drove about 500 hwy miles in one day and was very thankful that the catch can captured that oil vs my intake manifold. This is an obvious way to keep my truck running for hundreds of thousands heart pounding miles! JLT made in America enough said!

    Plug-n-Play: Easy install!

    Posted by Mike C on Oct 24th 2019

    What attracted me to the JLT the most was the ease of install and plug-n-play connections. I liked having the option of keeping my stock PCV hose and returning to stock if I sold the truck, etc. My rating is based on initial quality impression and install - 5/5 for sure. I don't see any reason why it wouldn't do what it's supposed to.

    JLT catch can

    Posted by Roy Giller on Oct 15th 2019

    Very easy to install and is made of great quality. It already had around 1/4 of an ounce inside the can after approximately 150 miles of driving. The catch can works very well. I am very happy with it.

    Easy to install on 2014 sierra denali 5.3l

    Posted by Joe on Sep 16th 2019

    Only had it on for a week, but installation was super easy, hoses plug directly in, no cutting and splicing at all, and took about 15 to 20 minutes at the most. I'm sure over time it will do what its supposed to do.

    Silverado Catch Can

    Posted by Chris Mason on Aug 1st 2019

    Very easy install, the directions are perfect. Looks like a factory part. The only thing I had an issue with is the shorter hose should be about 2 inches longer in my opinion. Easiest kit on the market!
