Silverado-Hareek

Yeah it's definitely the colder weather. I also drain after driving the truck for a while to make sure all of the oil and water is warm so it flows and isn't frozen or coagulated in any way. And just to clarify again for anyone that may have misunderstood me, my original point a few posts back wasn't to knock any particular brand of catch can. I was merely trying to state that I don't see any way you could ever go 5,000 miles between drains in a cold weather climate.

I don't think so because of the ratio of oil versus water. I'm getting approximately 2 oz of oil and and 4 oz of water. It's hard to tell the exact difference because of the moisture content but that's close enough. So based on the oil quantity, I don't think there's anything wrong. Being that it's mostly moisture in the drained fluid, that's pretty typical for an engine in the winter time to have a lot of moisture like that. It should settle back down to just oil in the summer. If it doesn't settle back down or if it were more than 2 oz of oil, I would definitely be concerned though.

I WILL forget you responded since you obviously are incapable of having civil discussion with another individual. For anyone else willing to discuss the issue, I'm here and ready to talk. For the record, I'm not a "fanboy" of RX. While I did buy their can, I agree there are other great cans available. If you take the time to read my original post from earlier today, I'm approaching this discussion based strictly on numbers and facts such us climate, engine type, # of miles, etc. I question the statement about being able to drain a catch can every oil change when you live in winter climates. Again based on what others and myself are pulling out of our cans, that doesn't seem physically possible without sucking gunk into your engine.

2 oz in Reading, PA every 750 miles? Is that a diesel engine or gas? Agreed every engine is different. But same engine, relatively same climate, and a 4 oz difference in stuff being caught per 750 miles....that's a can performance issue in my book. At any rate, I still don't see how you can go 5,000 miles in winter conditions based on the photos people are posting in this thread. In the summer time yes probably.

I'm not sure why it says "off road use only" but I believe that wording is referring to something else....like the can model or an extra install step. But I don't' think it's referring to the right diagram versus the left diagram in that same picture. PCV gases should only be traveling through a catch can in one specific direction and that direction does not change by the type of driving conditions you are doing. You are correct the PCV gases should pass through the port that connects to the filter chamber/media first. The other port is the "clean side" so to speak of the catch can and its the outlet port of the can.

I don't see how this is possible unless the can doesn't work as well as the RX or it has a 40+ ounce reservoir capacity. My RX can is draining approximately 6 ounces of fluid every 750 miles here in Virginia. At that rate it would need to hold at LEAST 40 oz for me to make it 5,000 miles. There's no way I'd ever go that long in the winter.

Yeah I'm getting about 5-6 ounces out every 750 miles here in Virginia. Mostly water. I'd expect that volume to drop significantly in the summer time when it's more likely to just be oil in the can.

There's a cross section of an RX can from 2011. I assume it's the same size as our cans. You can see there's no way you get the full 32 ounces of storage capacity. You get 1/3-1/2 of that amount at best.

I'd say at 10.5 ounces you were close to playing with fire there. I'd drain it more often based on what you got out. I wouldn't want mine to have more than 5-6 ounces or so in it just sitting there at any given time.

Based on what I've read after countless hours of research on the internet, it seems to be the most effective on the market. There are other ones that are just as great too. But there's a link somewhere where someone tested multiple cans and found the RX to catch the most "stuff" out of all of the cans tested. That sealed the deal for me. That and pretty much every Corvette or Camaro forum was also recommending RX.

It says 1 QT on their website which is 32 ounces but I think that's total can capacity or interior volume so you have to account for the filtration portion at the top. I'm not sure what the actual capacity of the safe reservoir area is but I've been draining mine every 750 miles or so in the winter to ensure it doesn't get overfilled. I really wish RX made their cans like some of the competition where you can see how full it is or at least unscrew the bottom to get an idea of how much storage capacity you actually have to gamble with.

Mine does the same thing. It will randomly clunk and shift hard into drive or reverse from park. And when driving around town and coasting either to a stop or slowing slightly and then giving it a little gas, every so often it will an abrupt/hard down shift and make a clunking noise. The truck drives fine overall other than those random hiccups.

The stuff in the can will freeze if there's a lot of moisture/water in the drained fluid. I left it outside in an oil drain pan overnight one time and it was solid ice the next morning. But with that being said freezing should only be an issue if your can is too full which would be a problem anyway because you don't want it to get too full and the mixture get sucked into your intake.

pull the negative terminal on the battery maybe and reset everything?

That logic kind of makes sense since BG will warranty your engine as long as you do their service according to their maintenance plan which is like every 15,000 miles. I'm at 13,500 now so it's getting close to decision time here... Sent from my iPhone using Tapatalk

Yeah it was like $140 for my wife's Hyundai Accent. I can't imagine what it will run on the Silverado. But the guy at RX said they advise against these services because the carbon particles that get pushed through the cylinders can get trapped between the ring seals and score the cylinder walls. So I'm not sure what to do. I'm almost thinking not to do it at all on my truck unless it starts having issues.

Sorry I didn't mean it that way I was just confirming that you should use 3/8" hose. The nozzles on the engine itself are 3/8" diameter.

Did you use the supplied bracket to mount it? Also what is the zip tie doing? Sent from my iPhone using Tapatalk

I've been pulling large amounts of moisture as well out of mine and it's definitely the cold temperatures. I'm not sure if parking in a garage changes that or not though I think it's just a function of winter fuel blends and driving around in the cold weather.

I disagree for a couple of reasons. First of all the stock line is a very stiff small diameter hose. Secondly, the PCV system works essentially like a vacuum in that the intake is sucking the gases out of the crankcase. If you increase the diameter of the hose, and the suction from the intake does not increase, you reduce the vacuum effect at the crankcase. Now I'm not sure if reducing the vacuum effect is bad or not, but I personally would want to keep that vacuum effect as close to stock as possible since the engine was designed that way.

The RX catch can comes with 3/8" hose from the seller.

Got our first snow down here. Just to be clear, I can switch back to 2wd in park as long as I don't shut the engine off right? Or am I supposed to do all my 4wd shifting in "drive"? Sent from my iPhone using Tapatalk

Did you tell them you could blow air both ways through the can?

Checking out their website and Gen5 website it's the same exact can and description. I wonder if mine has the internal and external check valve installed since the bag of parts they send you is standard between all vehicles.

Interesting so between November 2014 and now it's been redesigned.
