About J&L Oil Separator Co.

J&L is a single-product company, and it shows. Its billet aluminum separators sit in the PCV line and use an internal filter to pull oil vapor out of crankcase gases before they reach the intake, which helps limit carbon buildup on intake valves.

The current Oil Separator 3.0 holds about 3 oz and has a quick-release tank you can drain in under a minute. J&L says its kits are engineered, machined and assembled in the USA.

What we carry from J&L

We stock J&L Oil Separator 3.0 kits in black anodized finish, listed by part number and by side. They are direct-fit, plug-and-play kits with OEM-style quick-connect fittings, so most installs need no cutting or tuning. Find more underhood upgrades in performance parts.

Applications include the Ford F-150 and Raptor, Super Duty F-250 and F-350, Ford Bronco (including kits for trucks built after the mid-2021 PCV line change), Expedition and Explorer, Toyota Tacoma, 4Runner and FJ Cruiser, Jeep Wrangler and Gladiator, and Nissan Titan, Frontier and Pathfinder.

How to choose

J&L kits are specific to vehicle, engine and side, so match the part number to your engine rather than just your model name.

  • Most vehicles need only the PCV-side (dirty side) separator.
  • J&L notes turbo engines like the EcoBoost F-150 may benefit from separators on both sides, especially if you tow.
  • Check the can at 500–1,000 miles to learn your engine's fill rate. J&L says most collect about an ounce per 1,000 miles and suggests draining every 2,000–2,500 miles.
  • Check more often in cold weather, when condensation builds faster.

Lead times & shipping

In-stock items ship from NVMOS in 24–48 hours. Some J&L parts ship direct from the brand or are built to order, so check the product page for timing or call us before you plan an install weekend around it.

J&L warranty

J&L warrants its separators against defects in materials and workmanship for as long as the original buyer owns them, once the kit is registered. J&L chooses to repair or replace, installation costs aren't included, and wear items like O-rings, modified parts, misuse and shipping damage are excluded. The warranty does not transfer.

J&L Oil Separator Co. FAQs

Where are J&L oil separators made?

J&L says its separators are engineered, machined and assembled in the USA. The company is based in Chesapeake, Virginia.

What is the J&L warranty?

Lifetime coverage against defects for the original buyer, activated by registering the kit with J&L. Wear items such as O-rings are not covered.

How fast do J&L kits ship from NVMOS?

In-stock items ship in 24–48 hours. Some kits ship direct from J&L, so check the product page or call us for timing.

Do I need a driver-side or passenger-side separator?

Most applications only need the PCV-side kit. Some turbocharged engines, such as the EcoBoost F-150, can benefit from a second separator under heavy loads like towing.

How often do I empty a J&L catch can?

Check it at 500–1,000 miles to learn your fill rate, then drain roughly every 2,000–2,500 miles, more often in winter. Dispose of the collected oil like used motor oil.

Is a J&L install difficult?

Usually not. The kits use OEM-style quick-connect fittings and need no cutting or tuning, and J&L says a typical install takes a few minutes with basic tools.
