Congrats on the install. It will definitely pay for itself the first time you empty it. Nice pic of the finished product.

The can looks great. The easy mods are always fun.

Thanks Matt...real happy with it. I will keep everyone posted on results since I do add up the miles pretty quick!

Went about 150 miles today and I opened the catch can when I got home. Already about a 1/8" of oil in the can. Cousin says I must have a lot of blow-by in my engine.

Catch can removes oil mist venting form your Pollution Control Valve (PCV) under suction from your intake manifold via your throttle body--not blow-by.
Blow-by is when combustion gases and by-products pass the cylinder rings and begin to accumulate in your oil--this can in severe cases pressurize your crank case. These vehicles can go 8k miles between oil changes, and yet still fill catch cans with oil when new from the factory. No oil dilution, just Hemi design.
Your Cousin is no mechanical genius.

Actually PCV stands for positive crankcase ventilation
Wow that is a lot for 150 mi, how did the oil look clean or dirty?

What's the purpose of removing the oil must? What r benefits to having it, and if u don't?

That oil will build up on the inside of your motor as well as on the back side of your throttle body. Long tern, this will hurt your trucks performance.
Short term...when that oil mixes with your fuel in the intake, it will lower the overall octane level of your fuel. This isn't too bad for a stock truck, but it is terrible for anyone with a tuner/programmer. Programmers add timing which is why they have 87, 89, 91, or 93 octane tunes. The more timing in the tune, the higher octane fuel you will need to prevent engine knock. Say you are running a 91 octane tune, with 91 octane fuel. Without a catch can, that oil will mix with your fuel which will lower your octane level to say 89 octane. Because the tune calls for 91 octane, your engine will likely get some knock, and the computer will pull timing to prevent any damage to your motor. This loss of timing, translates into a loss of power.

Thanks for sharing your knowledge, I also was wondering exactly what the catch can does because I'm not the most technical guy. So I'm assuming with the catch can you just open it up every once in a while and dump it out?

Correct. General rule of thumb is to dump it out at every oil change, but its so easy to get to that most guys just empty it anytime they open the hood.

I'm not sure but i doubt blowby past the rings is causing the oil mist.
I'd think it was more the foam in the oil created by the crank passing through the oil and flinging it up on the camshaft,that creates mist/foam,blowby just creates pressure but no mist.
Anybody done a test to see if the level of oil inside the crankcase changes the amount of oil going into the can.
