Interesting seeing all these threads on the catch cans, and it does seem like it could be a useful device. Unfortunately in California you can’t do anything to alter the emissions system. If you have one of those installed it won’t pass visual inspection during a smog check.

I live in socal and have a 17 so haven't had to inspect yet. When it's due I will just pull can, nipple hoses together under engine cover and tywrap secure until I can get home to reinstall!!
No fn way will I allow that crap into my motor if there is a simple relatively cheap security blanket to help keep throttle body, plenum, etc somewhat cleaner!!!

Yessir, I'm ready. Brand new Ariens 32" snowblower, generator (just in case) and a few cans of fuel ready to go. The Power Wagon helps too so I can get the milk and bread to make milk sandwiches lol

How about you?

Good to go. Plenty of charcoal for my outdoor grills. Gas for my Toro, fridge stocked. Might have to make a booze run.lol. If we get a sever ice storm, I am expecting to loose power. No generator though. I do have a gas fireplace for plenty of heat though.

Did you get the Fuel injected ariens ?

Yeah I live in the woods so we always have a chance of loosing power. I also have a well so if I dont have power I dont have water either. So a generator is a must to make sure we have our utilities.

Good luck and stay safe!

Aproximately 12,000 miles worth. Truck is at 20,000 miles. Imagine all this run through the intake and valves

I’m just curious, is it normal that the hemi has more blow by than the V-6? Because I haven’t noticed any drop in oil so far on the dipstick, but I’ve only got about 12,000 miles on it. I just changed the oil and like the last change, it was still right at the top on the dipstick.

Hemi runs about 7 quarts of oil anyways but no I’ve never noticed any drop in oil. Always at the top full mark. Plus if you notice the liquid in the bottle is straight black. My oil only has 4,000 miles on it so far and is not straight black like that is. It’s a mix of crude as well from fuel burning and moisture in the air

I have found that in the cold and damp weather my catch can seems to fill up a little faster. Just check it more often. Better than all that gunk going into the intake.

You will get more condensation in the cold months that the can will catch. As you said, be sure to check it more often.

Sorry guys, I ended up getting on the road shortly after posting this yesterday. That cup is a 9 ounce cup, so I'm guessing that's 4.5 ounces (ish) in that cup. And, my CC is a Moroso and yes, it has the little drain valve at the bottom so I don't have to unscrew the enter can. I pull the little cap off and open the valve to drain it. Prior to my 2015, I had a 2013 with the CC on it. My 2015 seems to fill up the CC about twice as fast as my 2013. I'm just not sure what would cause the difference.

Just dump the can into something and screw the can back on. very quick and simple. I like to pour it in a big gatorade bottle so i can see the look of the oil. Then empty it in a oil container and get rid of it anywhere that accepts waste oil like an auto zone, walmart, etc...

Nick, im talking about cleaning the crap out that has been accumulating without the catch can. my truck doesnt have one yet. so it has had since 2014 of that crap going into intake valves etc. so once i install the CC i was wondering if i can do anything to clean the stuff thats in there. i understand how to clean what is caught in CC once installed.

An induction service helps, but without taking things apart you won't get all of it. I use the solid start stuff with the s-hose to spray in at the TB every 15k or so, but it's hard to find outside of shops that use it and finding a dealer/wholesaler. Gumout has one that's fairly popular as does Seafoam. Either one would help get some of it out of the intake. Since we're port injected you can also run something with good solvents like the Redline S1 in your tank to hit the back side of the valves. If you have alot of crud I would be ready to an oil change immediately as it's going to darken up alot. I also run a good fuel additive every couple of tanks just to help with the corn gas and keep everything clean.

See what @joshuaeb09 stated. that is good info. I would start running the Red Line Fuel treatment in it for a while at a minimum. we can set you up with that as well. If interested PM me and we can set you up with some Red Line fuel treatment, 7 quarts of Red Line oil, and a UPR catch can setup. Your HEMI will love you when we are done with it!!!

They definitely prove to be a worthy investment. The 1st time I emptied a catch can was the exact moment I knew for sure it was worth every penny.
