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.

    JTL 3.0 oil vapor catch can

    Posted by Dylan Eckery on Sep 8th 2020

    I ordered the JTL catch can to minimize oil vapor from being reintroduced to the intake manifold from the PCV valve. Installation was simple, I followed the JTL installation video from YouTube. No issues or change after installation, just hoping to prolong the life of the Gen 5 5.3 liter V8.

    Simple plug and play solution.

    Product is nicely made, installs easily in minutes, and looks like OEM. In my case, '19 Sierra 5.3L, it wasn't even necessary to R&R the air box to reach both fittings.

    oil separator/black

    Posted by Joshua Coker on Aug 6th 2019

    This is my 3rd purchase of these oil catch cans/separators and they are a vital purchase!Your engine will sustain damage if you don't have one of these on a GDI engine.It catches around the 3 oz. capacity at each oil change that would have gone through the combustion chamber causing corrosion of the intake manifold and valves.Get one or suffer a HUGE bill later.The install is simple and the quality is top notch.The price is high(there are more expensive ones out there) but a top end rebuild is way more expensive!
