    Catch cans

    I dont have one so I'm supposed too be sucking gobs of to into my engine. However, I fill with 7qts but whenever I check the dipstick on oil-hanging day, the level is maybe two hairs down from the max level. These things are frauds.

    I conclude the only engines on which catch cans catch cans catch oil are beat and near death.

    Your conclusion is not only wrong but an ignorant statement as well. I will almost fill my catch can between oil changes and my engine is far from death.

    As accurate as your observations are about the actual losses / dipstick level, it'll still make some folks butt hurt :^)

    I have one and it works as it should. Catch cansDoes everyone need one, no.... in warm weather I can go months and not have to drain it(oil). With cold weather (40 deg down) I will have to drain it once a week, not from oil but mostly water. That’s driving about 250 miles weekly. It’s not worth having one in my case. And if I take the 4 ozs the can holds and divide the by the 250 miles worth of engine rotations... I have no clue what that would be but that 4 oz would make no difference to my engine.

    In my Hellcat I emptied a nearly full Billet Technology catch can just before getting an oil change.

    Each car would vary. If you install one and it does what you want it too, then it works. It’s not going to hurt the vehicle it’s installed on unless you don’t drain it. Then maybe crankcase pressure could build and cause a seal or two to fail. I think most hemi’s have two ways to help vent case pressure, but I’m not sure

    I actually had a can installed on my car. I just picked up the intake to sell. I'll take some pics tomorrow to show EVERYONE just how not worth it a catch can on an N/A motor is.

    Hint: the intake is in a trash bag in the trunk of my 300, as to not have oil dripping all into the trunk liner
