math_10silverado We have several new designs coming out that eliminate all crankcase pressure issues and they will be available in the next month or two. Feel free to contact me for any questions as they are a blessing for all engine seals and letting out every bit of positive crankcase pressure without causing any vacuum issues. We have several patents in process before we release as it's a completely new design for any climate or power level. Feel free to PM as I can guarantee it will perform perfect in any conditions. Joe

Sorry to get so technical, I just meant that it's very important to explain the function and how performance can be affected in different temperatures with different catch cans and how critical location is for winter months. You're all set as long as your not freezing or having restrictions or flow issues. Feel free to pm me or ask any questions. Have a great weekend, Joe

That location is ok if you do not experience extreme winter cold and you drain the catch can regularly. I just try to keep the UPR Catch Can System in a warmer location as we have taken so much time to develop the best internal coalescing system with multiple stages of coalescing screens, filters and chambers with different holes and baffles throughout the internal diffuser system. Many boast of how many chambers and other variables that mean nothing. We have worked very hard to ensure the oil coalescing with a few friends from FRAM and they told us the science behind proper oil coalescing and engine temps that allowed us to build the best internal design and performing catch cans in the marketplace. As long as the location works for you that is all that matters and if you need to adjust you can move your setup closer or further away from the engine heat depending on the efficiency of the catch can. BTW, hope everyone had a great 4th! Joe

Just a heads up with catch cans in cold weather. 1.) Drain them immediately after your done driving for the day while the contents are still warm and will flow out. 2.) Make sure you catch can system is mounted close to the engine or exhaust so it operates at engine temps or close. 3.) Most important is not to mount catch can far away from engine heat and make sure the can is designed to coalesce efficiently in heat. 4.) Some people even run a cloth winter sock on the catch can or wrap them to keep them warm and insulated. 5.) Never leave the contents in the can from the day before in freezing weather or can blow a seal or vc gasket if its overfull. UPR Catch Cans are designed to run in the hottest locations and weather and coalesce properly in that environment so you will never experience any of the above issues with a UPR Catch Can if you follow the simple steps. Just wanted to share. Everyone grab you UPR Catch Can Systems while the 4th Of July Sale is running and you can see the code in the image below or on the rotating banners of the UPR Website homepage. 10% OFF CODE: USA2019 Thank you and have a happy and safe 4th of July!

You can Block one of them off if you prefer to keep the oil cap. I really recommend the full system as I never like to take any chances with allowing oil into the combustion chambers and it's not about the cost or profits etc. My main concern is having a bulletproof system that protects the engine anywhere oil can sneak in.

The system is designed to pull the fresh air through the CSS mounted at the oil cap. The CSS can be removed very easily in a minute or two to be able to add or change the oil whenever you like. I always recommend the CSS for the best protection and to keep the filter and airbox fresh and clean. Joe

14-17 GM CHEVROLET GMC TRUCKS 5.3L DUAL VALVE CATCH CAN PLUG N PLAY ™ The new UPR Dual Valve Catch Can System without the CSS includes the connections needed for both sides. The WOT line will go from the catch can to the passenger side of the intake tube and the driver side valve cover where the oil cap used will be replaced with our quick connect insert and runs a line from the oil cap outlet to the driver side of the air intake. Feel free to PM me any questions you may have. This is was to be able to offer Full UPR Dual Valve Catch Can Systems with and without the CSS for the best of both worlds. We wanted to be sure to offer the best kit for each application. We offer kits with and without for the 5.3 and 6.2 with and without cold air intakes. Thank you, Joe

The simple explanation of the PCV system is that it's a dedicated vacuum pump to scavenge the crankcase and evacuate any positive crankcase pressure. The issue occurs during normal PCV function while the dedicated vacuum source is eliminating crankcase pressure and improving ring seal. PROBLEM: The factory vacuum source is strong enough that it can and will pull out any fluids that are still vapor. The newer the vehicle the stronger the vacuum source will be, resulting in much higher amounts of oil and unburnt fuels being scavenged from the crankcase through the PCV system and ultimately into the combustion chamber where they cause disruption in the efficiency of the cylinder firing and often results in detonation or pre-ignition. Then slowly the engine will start to build up a slow and inevitable collection of oil that starts to coat the intake, runners and combustion chambers. When you install a properly functioning catch can and not some empty container with steel wool or home made dividers in it, you collect almost everything instead of collecting a little bit of oil and thinking you solved the problem. These empty cans are only catching the solids and the vapors are still getting through. That is where UPR has taken the time to develop a multi-stage, multi-chamber catch can system that will deliver the best performance in both coalescing and condensing in hot or cold applications. SNAKE OIL: There have been a lot of unethical businesses that market catch cans with scare tactics; stories of blown engines, a bunch of Direct Injection nightmares, and so on. That makes it easy to be swayed, or for someone to make light of the benefits of catch cans without ever understanding the true function and benefits. UPR stands behind their Catch Can Systems with a full warranty and guarantee to deliver performance and mpg benefits across the board.

Sorry, I haven't responded in a few days as we have been working on some new products. The CSS is very simple to R&R and with all the customers we deal with. I've come to the conclusion that it's best to have each individual do it a few times to see what works best and they feel will be easiest to explain to the TECH working on the vehicle. I prefer to disconnect it from the intake and then you can easily spin it to undo the lower UPR Plug n Play™ fitting then use a 19mm wrench to unscrew the UPR Plug n Play filler neck fitting. Joe

1. The vacuum issue is something you might experience at idle and goes away when your throttle blade is open.This is perfectly normal and our system will close the WOT check valve at idle from the stronger primary vacuum and then it will open once the vehicle is under load. 2. The CSS only requires one fresh air in source and the flow needs to be bi-directional for the fresh air entry point of the PCV system. You don't want conflicting vacuum sources at both ends of the PCV system. 3. Cooler vapor is an easier way for inefficient catch cans to condense oil vapors. Our system was designed to coalesce the oil in hot or cold with all the stages and chambers and custom stainless filters - screens that are installed in the diffuser tube and the bottom of the diffuser shield. The cooler the location results in a ton of unwanted condensation and moisture and requires a lot of useless maintenance and time wasting. Just a quick bit of info for everyone to understand the higher end more complex mutli-stage, multi-chamber system's better. Joe
