But how??? If you understand the principle of the oil catch can/ or the factory hose which goes from point A: PCV valve to B: the intake, I don't see how the oil catch can can cause the rear main seal to leak. Unless like you kinda stated, the fluid freezing causing a clog or it's filled up to the top and causing a vacuume block. I live in the south, Texas and it's rare to get freezing temps so I'll never exp what people up north have to deal with.

 

 

I really want to put the can back on my truck but a little skeptical since the dealership said that the can was the reason for the rear main seal to leak

Never and mine has seen temps for a few years in the negative degrees in Jan/Feb. have had mine 4 years maybe

 

I drain mine every 3-4 wks roughly

 

Just drained Friday while doing an Oil change

that is somewhat of an odd color? Do you think your getting a little coolant in your oil? I have never drained anything like that before just wondering?

That's normal moisture for cold weather...all engines put that out. Mine does it for short trips in cold weather, nothing like that for long trips or warm weather.

Condensation from running the engine cold. It would burn off some moisture on a long trip. Mine fills up with oily water once a week in single digit temps. Even had it freeze into a big ice chunk in subzero temps.

It's normal from November-April then it goes back to normal oil colored and less fluid

This is a very normal color, especially in the colder months where more condensate is present.

I just emptied mine after 550 miles and got 45ml of same looking stuff. I let it sit overnight and it separated into 4 or 5 different level of colored fluids. I tried to post a pic but it keeps saying over 1meg and too large. Can't figure out how to shrink image. Looks really cool though

Its probably all the mixes of gases, vapors and oil that makes it that color :)

Would be neat to see it! I understand I am far to old to be figuring out to pump pictures onto this forum

It's a shame that so many dealers take advantage of aftermarket parts being the culprit for engine problems and or seal issues etc.

 

The only way a catch can cause a seal to leak is from the cheaper more faulty check valves failing or a blockage in any of the lines that are sagging and allowing fluid to collect between

the catch can and the valve cover. This will allow the line to freeze fluid-solid in that area if the check valves do not flow properly or the system does not command enough flow / vacuum.

 

Then back pressure is created and causes seals to leak and or build up so much pressure in the crankcase that it finds the path or seal with the least resistance and pushes past it. We

are having a giant influx of customers from all other brand catch cans switching to our new UPR Pro-Series™ Check Valve and it has been able to eliminate flow issues for cold weather

and allow the system to flow properly.

The color is ( very normal ) when you mix gas, oil, and condensation. ( I see this with many forums over and over since mid-2006 and watched it run a continuous learning cycle to newcomers )

 

The condensation is more of a product of the catch can than the engine as the internal engine heat evaporates the condensation in minutes. Now when you get to the placement and design of the catch can, that's the true culprit to all the condensation and moisture that builds up in most catch cans today. There's a reason we have so much time in the design and position of our catch can system as we have had to improve the internal coalescing function and oil control to be able to perform better in hotter location to eliminate the need for having to drain and monitor the catch can so frequently.

 

This is the single biggest reason a manufacturer will not install catch cans from the factory. You will notice that we install our system near the header to allow the can to maintain proper operating temperature and greatly reduce the amount of condensation that builds up in the system for less frequent monitoring and maintenance. I personally have worked on improving the catch can function so it would be more user-friendly and require less maintenance.

 

For anyone out there that wants to have less maintenance, you can relocate your catch can system to a warmer location to reduce the frequency and amount of moisture collecting in the system. Also, note that catch can systems with poor coalescing and oil separation properties will not do as well in the hotter locations and that is why so many choose to mount them in the coldest location as it improves the lack of performance in so many catch can designs.

 

We strive for continuous improvement in our internal coalescing properties and oil separation. keeping all our systems modular in design allows us to be able to develop upgrades that can be added to any of our systems as they become available.

 

I know this post was more than just information about condensation. But, I really want everyone to understand the information and knowledge we can share with years of experience and development in oil separation and the true PCV function.

 

Thank you, Joe

Yes, do it. I had the same issue until recently. I was going to change my airbox filter and found a nice pool of oil in the tube and even in the airbox. and a bunch of dried oil on the actual filter. You can hear the surprise in my voice when I open up the airbox haha

 

 

 

Since it has been a while would you mind telling me since your can installation has this stopped? Also do you notice your oil level dropping where you have to add oil to the crankcase at reg intervals? May I ask what was the cost of your set-up? Thanks so much....

      Low fuel pressure after installing new fuel pump

      Replace the fuel pump with an OEM AC-Delco.

      Low fuel pressure after installing new fuel pump

      By Gilkey96 · Posted

      Hello, first time posting here. I have an 03 Chevy 1500HD with the 6 liter gas engine. The truck ran fine until the fuel pump died on me and had to get it towed. Replaced the fuel pump with a precision pump from O’rileys and changed the fuel filter while I was there. The truck will run and drive now but it wants to idle around 500 rpm when in drive and it tries to stall if you touch the gas. It drives fine though, just doesn’t want to idle. Put a fuel pressure gauge on the rail and only have 50 psi. I guess these trucks should have 55-62 psi to run right. I thought the regulator might be the issue because when I would unplug the vacuum hose it jumped to 56 psi. Replaced the regulator and no change. The only thing I can think of is that I was sold a faulty fuel pump. Any help would be appreciated because I’d rather not have to take the bed off again if I don’t have too. Thank you!

      AFM Experience

      By diyer2 · Posted

      I've been wrenching on GM trucks for 17 years. And I need to get something off my chest because it's been weighing on me for a long time. After all that time, all those motors, all those people standing in my bay, I've figured out there are really only two kinds of owners. The ones who already know about this. And the ones who are about to find out the hard way. A guy came into my shop a few weeks back in a 2018 Silverado 5.3. Sharp guy, maybe 35. Knew his truck cold. He'd been on the forums, read the threads, done his homework. He only rolled in so I could double-check a little module he'd already plugged in himself. Wanted a second set of eyes on it. Ten minutes, in and out, drove off happy. Two days later, a completely different story walked through the same door. Older fella this time, in a 2016 Sierra. Gorgeous truck, clearly babied, not a scratch on it. Wedding ring. Looked like a guy who took care of his stuff. He was in because his engine had started knocking on the way to work. And by the time I got the valve cover off, I already knew it was too late. Lifter collapsed. Cylinder 5. Camshaft chewed up. The whole top end shot. Same kind of truck. Same motor. Same roads, probably the same dealer. The only thing separating those two men was information. I've been at this since 2008, and I've worked on everything GM puts out. Silverados. Sierras. Tahoes. Yukons. Suburbans. Escalades. The 5.3 and the 6.2. Doesn't matter which badge is on the tailgate. They all carry the same problem. So here's the information one of those guys had and the other one didn't. It's called Active Fuel Management. AFM. GM started building it into their V6s and V8s back in 2007 to squeeze out a little better mileage on the highway. Maybe a mile or two a gallon. All to hit government fuel economy numbers. The way it works, the motor quietly shuts down half its cylinders when you're just cruising along. And the little lifters that pull that off have a tiny pin inside them that's constantly clicking in and out. Lock, unlock, lock, unlock. Hundreds of times a drive. Thousands of times a week. Eventually one of those pins wears through. The lifter drops. And it starts grinding the camshaft down like a chisel on butter. And what nobody tells you is that the shudder you feel around 40 or 50 mph? That's the system cycling. Every single time. Here's what really gets me. The pre-2007 trucks, the ones without AFM, they're bulletproof. I've got customers still daily driving them with 260,000 miles on the odometer. Not a problem in the world. GM took a perfectly good motor that would have lasted a lifetime and bolted this system onto it. And it is wrecking engines that should have run forever. The guys who hang around the forums already know all of this. So do the techs. They handled this years ago. They didn't sit around waiting for the dealership to mail them a warning letter, because that letter is never coming. It's the guys who figured somebody would've told them who end up on my lift. And I want to be clear, because this part matters. Maintenance has nothing to do with it. I've torn down motors with barely 30,000 miles on the clock. I pulled apart a Tahoe last summer with 24,000 on it. Practically a brand new truck. Owner had it less than a year. Spotless oil. Best synthetic money can buy, changed early every time. Made no difference. I've seen guys with full dealer records, every interval stamped. Made no difference. The oil changes were never the problem. The pin was. And no amount of babying that truck stops that pin from cycling every single time you drive. That's the part that eats at me. These are good motors. Take the AFM out of the equation and a 5.3 or a 6.2 will run 300,000 miles and never blink. So a few years ago I started telling every single owner who comes through my doors the exact same thing the smart guys already knew. Get yourself a FullForce disabler. It plugs right into the port under your dash. Couple of seconds and you're done. It just tells the computer to leave every cylinder running, full time. No more cycling. No more beating those lifters back and forth every time you turn the key. It doesn't reprogram anything. Doesn't touch your tune. And unplug it before a dealer visit and there's absolutely zero trace it was ever installed. I've had customers come back at 40,000, 60,000, 80,000 miles after I put one in. Zero issues. The trucks run smoother. And the lifters aren't getting beaten to death every single drive. I won't sit here and tell you it's magic. A lifter that's already damaged is a lifter that's already damaged, and this won't un-ring that bell. But it takes away the one thing causing all that wear in the first place. That's the whole game. You don't need a five-thousand-dollar delete. You don't need an expensive tune. You don't need to tear anything apart. You just need to stop the cycling. I'm not writing this for any company. I'm writing it because I'm tired of watching the guys who didn't know pay four and five figures for it. I'm tired of being the guy who has to break the news. I'm tired of knowing that the guys who did know fixed the whole thing for the price of a tank of gas, and the only difference was that somebody told them first. If you drive a Silverado, Sierra, Tahoe, Yukon, Suburban, or Escalade from 2007 or newer with a V6 or V8, you've got AFM. You've got those lifters, and they're cycling every single time you drive. So be the guy who already knew. Not the one I'm scraping metal out of next month. EDIT: A bunch of folks asked, so here it is. The one I put my faith in is FullForce. This is where to find it: https://www.tryfullforce.com/products/fullforce™-afm-dfm-disabler They back it with a 60-day guarantee too. I've handed out more than I can count and not one's ever come back to me. Not one. See less

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Thanks for following along. I'm not author material, my tenses are all over the place and an editor would have a heck of a time cleaning up after me. Reading and writing is still a fun pastime though.   My new scanner came in yesterday, wow, where the heck has this thing been?! It connects right up to the Blazer, there's all kinds of bidirectional tests like EGR activation and percentage, toggle the fuel pump relay, EVAP purge valve, IAC control, AC relay, reset the transmission's adaptive learning, toggle shift solenoids and TCC lockup, and I can reset fuel trims with the click of a button...all things I could have used over the last 60 days!   It's also telling me there is a stored code in the ABS module for front left wheel sensor open and something about the brake switch. The ABS dash light works. It illuminates normally during the self-test at key on/ start and that's it. I cleared the codes and will see if they set when I take it out later. That, and I'm going to get (hopefully) real data on timing and cam ******. The PID's are there.   I connected the tool to my truck...holy smokes. Newer vehicles make early OBDII vehicles look like 8-bit, pixelated, early Nintendo stuff. This? This is like wearing 3D virtual reality goggles playing one of those elaborate, cinematic video games with seasons and plots in comparison. There are SO MANY modules and SO MANY tests and SO MUCH data. There's a scanner sequence for filling the coolant...   End of the day, it's a tool with way more power than I need, but the versatility to do old and new is there (and I need an adapter to connect it to my OBDI Camaro). It will allow me to do the first pass of diagnosis when out-of-warranty vehicles need help, and it will enable more DIY maintenance like brake system bleeding, ABS bleed, etc. I probably over-bought here, but, mission is accomplished.   Enjoy your Sunday...I need to shut this machine down and go get ready for the week ahead.

      Not that I've read, after all the issues they've had in the past I'm pretty sure they learned their lesson.
