J&L 3.0 Oil Separator Can Extension
Fit and finish are perfect. Screwed on easily and stayed snug. Happy that I opted for this to double the capacity of the catch can as in one 24 hour period I drove home and back to work (24 miles in total), and I collected 20ml (.675oz) of liquid. Granted it is cold weather and 2 short trips where the engine really doesn't have a lot of time to get hot. But that is my normal driving routine.
Extension for the oil separator
The extension I purchased for the oil separator double the capacity so I don’t have to empty it between oil changes. Fits perfect and doesn’t leak at all. An excellent addition to an already great product.
J&L 3.0 Oil Separator Can Extension
Bought the extension for my 22 Frontier to go with the J&L separator for longer drives before emptying the can. Perfect fit. Still had plenty of room in the engine compartment.
My truck runs better
I added the oil separators to both the left and right side of my F150's engine, My truck runs much better and I'm amazed at how much oil the passenger side collects. The quality is great and installation is very easy.

Inside the oil separator there is a filter. The filtered side of the can should always go to the PCV valve or “dirty” connection. The filter is what turns the oil vapor into liquid form to be collected in the basin of the unit. You want this to happen as it is entering the can. The open port will run to your intake.
In most cases you only need an oil separator on the PCV side (dirty side) of the engine. This is the side that is under vacuum/suction most of the time while the vehicle is running and driving. The clean side typically is only used for venting when the PCV valve is closed which is under moderate to high acceleration.
Some turbo vehicles can see oil in the clean side, such as Ecoboost F-150’s when they are exposed to frequent towing conditions.
On non-turbo applications anything short of road course racing you typically will not see a drop of collection out of the clean side.
For most Ford applications there is a grey or green tab, you press in this larger tab. It is a button; it will release the fitting and you pull up on the fitting with the button pressed. ***DO NOT REMOVE THE CLIPS FROM THE FITTING! YOU WILL BREAK THEM!!***
For GMC/Chevy applications there is a single button release. This release and the location of some of these fittings can be tricky. You must press the bottom squarely and pull the fitting straight off. Many people make the mistake of pressing the button too hard and it flexes the release. Take your time and it will release. The 5.3L intake fittings are the toughest due to their location.
Most applications average about an ounce of oil every thousand miles. However, there are many factors in collection rate as every single engine is different. Factors such as driving style, climate, engine condition, oil level all vary and effect collection rate.
People in cold climates will have to check their oil separator more often in the winter months due to condensation build up occurring in the oil separator itself. In these months, the air entering the can is significantly hotter than the ambient air temp. This results in condensation build up (think hot shower in a cold bathroom).
We recommend everyone to check their oil separator at 500-1000 miles of driving to get an idea of how often it needs to be serviced. The can holds 3 ounces without the optional extension.

The specs on the screws are M4 x .7 x 10mm, they can be found at just about any hardware store.
Sometimes when the oil separator is over tightened it can be tough to remove; also some oil separators are much more accessible once installed than others.
If you are having trouble removing the oil separator reservoir, try removing it from the bracket or even vehicle to get a better grip on it. For units that are really tough, we recommend a rubber oil filter strap wrench. You can use this in combination with a rag and typically remove them without damage.
When reinstalling the can bottom, treat it like an oil filter. Screw the can to the bottom of the O-ring. Give it another ¾ to 1 full turn. No more, no less.
No! Dispose of this nasty oil that is mixed with fuel, water and everything else where you would dispose of your oil change oil. Many auto parts stores will take your old oil for free of charge.
If you read the fine print on any warranty contract you will find a lot of reasons your warranty can become void; installing aftermarket parts can be one of them.
However, per the Magnuson–Moss Warranty Act proof would have to be provided that the after-market part caused the failure.
