Joe -
So how often are you needing to empty these cans now?
What safety feature is there in place to assure that a can does not overfill and cause a large (possibly damaging) amount of oil and contaminates to be ingested suddenly?
Does the can, for safety reasons, decrease efficiency once it it exceeds a certain level of fluid, i.e. an overfilled bypass effect?
As I said in my post I understand them and their benefits, I just wanted to real world feedback as well as a better understanding of the "required maintenance" and risk that failure to maintain that level of maintenance poses.
Also can you provide a quote for one for a 2019 Classic 1500 with the 5.7 Hemi?
I'm glad you asked these questions as they are great for everyone to know.
1. How often do you need to empty a catch can?
Answer: Normally you empty it between oil changes unless your engine passes more than
5oz. of oil through it between oil changes. Normally you will see 2oz. to 3oz. of oil collected.
2. What happens if I forget to maintain my catch can and the oil level over fills?
Answer: The oil level will fill to the top and then it will slowly ingest a very small amount of oil
in a solid fluid that works like a slow leak and it will not harm anything. Once a can overfills it
will not suck in a large amount of oil suddenly as the air will always follow the path of least
resistance.
We have tested overfilling catch cans on both the 5.7, 6.2, and 6.4 engine and on a few ram
trucks and a several chargers from stock to supercharged. One of the trucks we ran the can
for 30,000 miles without emptying it. It still proved to be better than running without as it
forced the oil to collect and coalesce in the can and then it was drawn into the intake slowly.
Why its better to allow the oil to coalesce first is because its not in a mist or vapor that can
travel much faster and further through the system. With a overfull catch can the oil is very
controlled and usually just puddles before entering the intake as the air passes over it and
cannot ingest any big volume of oil unless the can was upside down and then your truck has
much bigger problems than oil ingestion.

We have so many catch cans out there it was easy to test and gather feedback for all the info
we've collected over the years. Hope this helps a bit more as we have seen it all and share our
findings.
You can follow the ebay link earlier in the post from the forum member that shared this info
about our catch cans.
