    If it is gurgling it may be full (any more than 1/3 full and the outlets from the coalescing chamber are in the contained trapped oil). Make sure to empty it when hot and engine off. The drain valve is open when in this position:


    And closed in this position:


    In the colder weather the can will also fill much faster due to the increased amount of water vapor in the crankcase and it will look a bit like chocolate milk.

    I can never believe the "carnage" that appears in catch cans - Gross!

    Have you taken a peek in the intake to see if there is any contamination / pooling oil? There should definitely be some buildup by each oil change.

    How often do you make hard wide open accelerations? (I'm curious for my own application) Thx

    Yes, there is oil in the intake; after installing the catch can, I assumed it was from the fresh air side that apparently dumps oil into the air intake.

    I make hard wide open accelerations very frequently... ;-)

    Re: Rx Catch Can "Gurgle"

    Something has to be hooked up wrong....can you post detailed pics of your install? Should be NO oil entering, and the can should catch the oil like all the others show.

    Oil will enter through the cleanside under WOT as well, but 95% plus is from the dirty side. Lets figure yours out Michael.

    To purchase the RX cans call direct: 941-721-1826 or go to: www.RevXtreme.com

    With the sound system off, I've been hearing a gurgle for the last week or two. I first thought it might be low on coolant and air in the system. Checked it, OK. I was about to make an appointment with the dealership to check other hydraulics like the tranny or transfer case or power steering when I decided to drain the catch can. I had planned on draining it at each oil change but I only have 4200 miles on the oil (and 3 1/2 months). I live about 80 miles east of Chicago so we're in winter weather. The picture shows the amount drained. Gurgling stopped.

    Yup! In the winter months drain it every 2k miles to see how much it is trapping. Every motor ingests different amounts so you have to first determine what your car is consuming.

    You do NOT want that in your intake air charge no matter what submariner thinks.

    Re: Rx Catch Can "Gurgle"

    I have had the same results. I’m super surprised at what comes out of the can. I am going to drain it in about 20 min, after I let it warm up, I'm half way to my next oil change. When it warms up outdide again I will take the intake off to look at the results as well as a cleaning to see it I can get the residual burnt oil off my valves that was caked on prior to catch can.

    It has been about 5000km since I last changed my oil and drained the catch can. I drained about 1/4 cup of oil. This product seems to be doing it's job. Micheal, I think there is something wrong with your can. Maybe post pic of install or you may have a bad can.
