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 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.

    By far the best catch can out there. It matches the quality and finish of more expensive brands at a reasonable price. I like that it comes with oem connections to make getting it attached easier. Installation is also very easy and has clear instructions. I'd recommend this product to everyone.

    Super easy install. Would like to see a catch can for the PCV going into the air intake.

    Extremely easy installation, less than 10 minutes with simple tools. All plug and play. Hose connected near the wire harness is a little cramped, but once you hear the “click” you are good to go! Nice product JLT

    So far i haven’t had the chance to have this long enough to see long term results but as far as installation goes it was extremely easy and painless to install! It’s a no brained to see where to plug things and the install videos are amazing. Highly recommend

    Easy to install, it was very simple to do the 1000 mile inspection of the can. I did make a quick video on the inspection.
