What's with the oil catch cans?

[wildh24]

I’m saying it works great. Apologize, no oil or debris in hose coming out of CC and into intake manifold. While the hose from pcv to can is full of yuck.

Thanks! I was trying to find that one on eBay, but looks unavailable.

Edit... Found one in silver.

Okay, i think im going to get one. Now which one? Seems most ppl go with billet or mishimoto, any preference on either. Obviously the mishimoto is more expensive, is it better? Is one easier to install than ther other? Thanks

Billet Tech has a listing on ebay with some free upgrades, $116 + shipping.

^^^^ you can find the same one that already in states. That was just first one I came across

Thanks for all the replies everyone I really didn't expect it to get this spirited on this subject. But I'm glad people on both sides of this answered.

Ha. Spirited is exactly what everyone here is about their trucks! Ask a question about what valve stem caps to go with and you’ll get the same enthusiasm! Great forum here.

Speedlogix sells an exceptional catch can. Pretty much the exact same as the Billet tech can. But half the price and you'll actually get it some time this century. And no, this post is in no way paid for, sponsored or in any way shape or form have anything to do with Speedlogix other than a happy customer who owns one of their catch cans.

It is 100% irrefutably, undoubtedly, unquestionably a personal preference. There is ZERO need or benefit on a stock naturally aspirated engine.

LOL for whatever reason this is contentious topic. Does it need it... probably not, does it hurt it..not at all. A catch can is just the term the automotive industry uses for a coalescing filter, they have been used in industry to filter oil out of compressed air systems for decades. Like @19reb said the PCV system is designed to vent the crankcase of un-burnt gasses that blow by the piston rings during normal operation and is part of the emissions control system, prior to the 1960s they used a draft tube to scavenge these gases and vented them to the atmosphere. Inevitably oil vapor also gets entrained in the gases and the coalescing filter "catch can" removes the oil vapor by coalescing it back into a liquid. Does it affect performance and efficiency, likely nothing significant to move the manufactures to install them from the factory, even on DI engines where catch cans actually have a larger impact. Due to increasingly strict CAFE standards bringing up fuel economy is obviously high on the priority list, think about the all the time and money manufactures have invested in engine technology to improve fuel economy, multi displacement, turbo charged 4 and 6 cylinders, e-torque, ram even went so far to design a secondary air-dam that drops down above 35 mph to pickup just fractions of an MPG. The added weight and R & D costs involved from any of these systems is significantly higher than an aluminum catch can. Logically, if there really were any significant gains to performance or efficiency you'd see these things on every truck rolling off the assembly line.

So how long - miles, does it take to fill up the can? What would happen if you let it fill up?

Check out teamrxp they make a great product. Little pricey but good products. They are working on mine since they don't make one for the trucks yet mine will be the first.

What is the part number? I looked on the website and didn't see one for Ram at all.

I assume the 2018 will work even the mounting bracket?

Yes it will. It'll bolt up exactly the same as any other catch can on our trucks or the 5.7 for that matter. It's the exact same mount I have and is pictured in my previous post.

My thought was for $100, it's not a bad idea. These things don't exactly wear out, so you could use it on future vehicles. Are you sure that oil gunk build up on the throttle body and the active intake (short & long runners) has ZERO negative effect on the engine? I'm willing to bet it's better to not have build up than to have it...

Logically, if there really were any significant gains to performance or efficiency you'd see these things on every truck rolling off the assembly line.

Not so sure about that. Hellcats have a built in oil separator for a reason, but people have found they still need a catch can to remove all the PCV vapors from the passenger side of the engine. I'm willing to bet the only reason we haven't seen these cans put on any vehicles from the factory because people barely maintain their vehicles as is... what do you think would happen if someone let the can fill with oil gunk (catch cans fill up with some nasty stuff) and overflow back into the engine, or worse, flow into the intake?

Forced induction is whole different animal than a naturally aspirated engine, boost pressure on the intake side creates issues with scavenging the blow by gases and the higher compression ratio makes it more critical to not have any oil vapor in the A/F mixture. But I agree with you 100% on the maintenance aspect, even if you somehow integrated a coalescing system into the oil change process where it was impossible to perform an oil change without draining the contaminates out of the catch can it still doesn't eliminate the human factor of going well past the required oil change intervals and risking the res. I'm a mechanical engineer by profession and have been in the field for a good while and try as you might you to protect a system for all variables the human element is near impossible to safe guard against. I was at a training seminar about 6 months ago and one of the instructors asked if anyone knew how long a Honda CRV could go without an oil change, the answer was 63479 miles apparently his daughter bought a brand new CRV and never checked or changed the oil and it seized up at that mileage. Pretty impressive actually.

Beside, as you mentioned, the A/F ratios, one of the biggest problems with boosted engines with internal heat exchangers(Hellcat) is oil getting in the exchangers and gunking them up. Which then makes it impossible for them to do their job correctly. If I'm not mistaken, this is the reason SRT added the separator in the valve cover in the Hellcat engines(6.2) in an attempt to fix this problem. The SRT separator does work, just not very well. Which is where a separate catch can comes in.

 

[19reb]

The amount of dirty oil I recovered from my catch can that would have otherwise went into my intake and gunked stuff up.

Only 1800 miles. Worth it in my opinion...

You guys take all the fun out of SeaFoaming an engine...lol
