What's good catch can?

[2020KGT2]

There was a concise response a few posts earlier. I’ve read many bad experiences on this forum, unfortunately I did my research too late and had to buy twice.

Early in the thread it's explained why the Mishimoto style cans are a superior design.

The only people I see pushing ADD W1 sales are the vendors because it’s a large markup. Try searching on EBay for a universal can. They’re cheap.

Appreciate the response. Which would you reccomend out of the 2. Mishimoto or Sxth?
I plan on only doing the PCV side.

I originally purchased the ADD W1 Dual inlet CC but quickly realized it wasn't compatible with the Injen intakes. You can re-engineer the can to work with the Injens but I didn't want to do that so I sold the Add W1 and got the Direct Fit Mishimoto. Love it...super easy install and it works really well. This is after 2 months and 1800 miles or so. A good tablespoon of gunk thats not going back into the engine

the BMS is maintenance free until the day it’s not...

I'm super confused by this. Am I just reading it wrong?

Depends on how much you’re comfortable spending and how much work you’re willing to do. I keep hearing people are happy with the affordable Mish copies, but you have to fab up a mounting solution.

For simplicity the Mishimoto PNP kit is the best bet. The single Sxth Element is about the same price and design without the molded hoses.

People seem to be very happy with the BMS as well. I just like the idea of seeing what I’m producing.

I have the dual Sxth Element and admit it’s a bit overkill having the crank case can, but it does catch a very small amount. I get maybe a 1/2 tsp at 3000 miles. Almost not enough to pour out of the can. It would probably work better if it was closer to the source.

Thanks for the reply. I did see the better design explained for the Mishimoto style cans, but I was under the impression that the BMS and SXTH element cans also used a similar design. But from what you're saying, it seems like Mishimoto has the better design all around.

So if I want the best performance, get the Mishimoto. If I want something that's easy to maintain, get the BMS. Sound right?

Also, what happens if you don't empty a catch can fast enough? Does it just act like there's no catch can anymore or does it do something bad? Actually, never mind. I'm sure I can find that answer with a quick google search.

It takes quite awhile for even an ounce or so to build up so chances of it over filling would be slim. At least in the climate of the PNW.

I have a small can on a built Harley engine that’s vented to the atmosphere. That’s the only one that I’ve ever had fill up fast enough to overflow. Those engines puke a ton of vapor.

In our case, the fluid would return to the intake as though there was no can. For these big cans to fill up you’d have to be very neglectful. Similarly, for there to be that volume of water to freeze and push, it would be from neglecting the can over a long time.

I guess the BMS would be ideal for someone who doesn’t do their own servicing and might forget over multiple oil changes. The no fail option.

In my opinion there is nothing really maintenance free... The day something happens to the “maintenance free can” Hopefully you catch it in time

Have you seen the BMS can. It is completly impossible that anything goes wrong with it, its the most simple and idiot proof design. Instead of guessing and speculating vapor, bring some real facts.

Your right everything is perfect... nothing ever breaks or goes bad... if you want to use it use it... Everything fails At some point

I mean I wasn't going to say something because yeah one of the hoses could get a rip or melt or come undone, but that could happen with the factory hose (one of which is reused) anyway. So I'm with you and don't see how anything could go wrong with the BMS CC that wouldn't potentially go wrong with the factory setup. So non-factor in my mind.

Is it that hard to left your hood time to time? Nothing wrong with looking at your stuff... You never know...but nothing last forever...they just don’t build things like they use to...

 

[Terry@BMS]

I really like our design but different strokes for different folks, run whatever OCC solution you're most comfortable with. Just be sure to get one on the vacuum side. On the boost side I've not seen any benefit on our prototype so right now I can't suggest running one. Won't hurt though.

Still no idea what the point is here. Just seems like a lot of incoherent argumentative rambling and periods. So I don't even know how to respond.

But long story short OP, yeah I am a fan of the BMS zero maintenance catch can as well for a daily driver at least. If you're looking for something more flashy there are better options looks wise though no doubt about that.

check this video out...

he said i think 6,000 miles and the dude lives in Canada but if he would have had the BMS He might never have a problem...I travel a lot ...a run from NY to Vegas or even California..I never stay in hotels I drive with either my wife or a co worker straight through...I Average about 900 miles in about 14 hours so if I drive for 42 hours that’s some serious miles in... just to be clear I’m using my circumstance which is an extreme... BMS might work for me ...maybe it can be overwhelmed... I myself like The ability to open it up and check it out... everyone is different

We’re talking maintenance free versus regular checking.... i’ll be more articulate next time... Also I’m pretty lit right now so don’t mind me

Lol. Roger that man! Thats all you needed to say for it all to make sense.

Sounds like you're doing a lot of driving. Stay safe out there on the open road.

So where does this crap go using the BMS maintenance free can?

Oil is separated from engine vapor within the OCC where it gravity drains right back in to the crankcase.

 

[Hockster]

This is my Mishimoto direct fit OCC after about 3000KM.

 

[General_Vodka]

Will be receiving my dual SXTH kit soon. Probably overkill but oh well.
