Oil catch can?

[Silverado-Hareek]

My Rx can came in yesterday. I decided to read through the thread again. Looking at some pictures it looks as though the check was redesigned, I'll post pics of the kit later. My slight concern is the size of the can and the hose lengths provided, which the latter I can just buy more if needed. It was right after I ordered the can they advertised the monster can being recommended in colder climates which is a fact of life in Canada, being as meticulous as i am if i keep the smaller can ill be draining every week in the winter for good peace of mind. I'll probably run this through the summer and see how it works.

 

 

Attached pic of the kit.

 

There's this silver clamp that isn't in any previous pics I have seen in this thread.

 

You can also see the silver check valve by the bag of fittings that's also different looking than others in this thread.

 

Yeah I live in Virginia and knowing what I know now the Monster Can would have been better for me. I was draining about 6 oz of oil/water every 650-750 miles in the winter so there's no way I could ever last an entire oil change interval. For the money though, I would say don't worry just use the can you have since it's cheaper and drain it more often in the winter. Once the temperature gets warmer outside the volume of fluid the can catches drops dramatically.

In winter, I empty mine after every road trip, and check it every time I fill up. Thing is only 3oz., so you have to watch it.

I know I would be probably everytime I would drive it in the winter.

 

On another note I decided at call the one and only local dealer in my town about them. Spoke to the shop manager and he stated he never seen a catch can or heard of them. He did state modifying the engine in anyway shape or form could automatically void the warranty which I found excessive based on what I read here. Even if you ran into some trouble engine related it could easily be restored back to stock state, my only issue is when they are doing oil changes and they make a note of it or immediately void the warranty.

 

This is a small town dealership we are talking about so I may get a hold of some dealers in the cities and see what they say. Problem with me is this is my local dealer where I plan to get oil changes done at.

 

This sucks.

 

UPDATE:

 

Here's a reply from the dealer I purchased the truck from.

 

"Hello Jordan,

 

This is Natasha from Southgate Service, I am emailing on behalf of Randy Folkmann in regards to the “ catch cans” you were inquiring about. In speaking to the shop foreman, the installation of the catch cans will not void any of your vehicles warranty, neither new vehicle or powertrain warranty will be voided.

 

However, in saying so. If the installation of the catch can causes a “ light” or a “ code” to become present, and the replacement of the catch can is needed or the concern was caused because of the catch can, that replacement or repair is not under warranty, as for it is a add on or accessory to the vehicle, therefore not included in the original make of the vehicle.

 

 

I hope that answers any questions you may have, however If you have any questions or concerns please feel free to reply to this message.

 

 

Thank you

 

Natasha"

 

 

I think I am comfortable now, I also asked her about how many they have seen come through their dealer if they have them installed. Their shop foreman obviously has seen some judging on his more informed reply than the foreman from my local dealer.

Finally a sensible answer.

This might be a stupid question but why can't we just put breather on it like the old days what's the draw back ??

[Jsdirt]

I don't see any reason why that couldn't be done. Might puke oil out the back all over the place though, seeing how so much ends up in the catch can. But that could be due to engine vacuum pulling it out as well. Hard to say ...

 

My '72 El Camino used to do that on the highway - think it needed rings. Would really puke out on high vacuum instances, like slamming the throttle shut at 3k - 4,500 RPM. Wouldn't know it from the power that thing had, though. Must've been a stout engine when it was new.

 

I cut a hole in a plastic ashtray, and stuck the breather inside that, to keep the oil off my valve covers and the rest of the engine, lol.

[Rme2513]

Yeah most of the old breathes had some type of foam in the to keep the oil from splashing out but unless it was rotted out or the oil drains in the heads might of been pluged and not letting the oil drain out quick enough. This is the first I have heard of the catch can makes me wanna look more into it. Has any one ever had the stuff in the catch can tested to see exactly what it is and how much is oil or water because like someone else said ain't no way that much oil can being sucked out after 5k miles and not see A loss when you change the oil

Strictly emissions is what I would gather. If you took your truck in to have oil change/service and you just had a free breathing system I am sure it would cause a stir at the dealer and they would try to void your warranty because they built the truck to meet the CAFE standard for emissions.

 

Emission systems are becoming more and more strict, just look at diesel exhaust systems. Now with DI systems causing sooty tailpipes I am sure some environmental person will take note of that and we'll have filters similar to diesel exhausts, no joking really.

I plan on putting mine on here this weekend and see how well it does in the excessively hot conditions we are experiencing in Alberta, I can't see it catching a lot as a result.

Wha kind did you get let me know how it works out

[thetruck454]

I know that creating a vacuum by connecting the pcv to the intake more efficiently pulls combustion gasses out of the crankcase so they don't settle out in the oil.

RX single valve system. Being in Canada supposedly was suppose to get a monster can (advertised right after I bought the standard can) to deal with the excessive liquid drop out in colder temps.

 

But seeing what Silverado-Hareek said below being in Virginia he just drained more often. However we see colder temps here, -15 to -25 (-4 degrees F average) degrees Celsius is common with the odd snap of -30 to -40 (-31 F avg). I honestly don't have a problem draining every 100+ mile road trip if it demands it in the winter knowing that I could be keeping this crap out of my intake.

 

My one concern though is of any possible freezing in the system itself, as water is known to drop out in this as well. One could argue the stock system could then theoretically freeze until the engine is warmed up and the engine bay is toasty engine to thaw anything. I mostly speaking of when I want to drain it will the little valve just freeze for a few minutes if cold enough.

I'm wondering why they re-designed the bracket and check valve?

 

Got a reply from RX, the bracket was redesigned to give more mounting options so we'll see how that plays out when I install it.

 

The check valve changed based on their suppliers of the material. The black ones are the plastic and the one I received is aluminium. They said it will swing back and forth depending on demand.

In other words ending up with crappy oil that could be detrimental further down the road, where as just venting could cause issues.

 

With these catch can systems you are still, to my knowledge, bringing out those gases to the intake? With the exception be you are just extending the pcv vent path and dropping out any liquid in the process in the can.

Yup, pretty much. All those contaminants now collect in the catch can along with oil vapor and water instead of going back into your intake.

Yeah in the winter months, I'll have to really keep after my Conceptual Polymer unit, since the "can" part of it is glass. The heat of the engine compartment will give me a little wiggle room, but I'll probably have to clean it after every trip, no matter how short.
