Assuming all hose connections are tight and there aren't any vacuum leaks or anything, and the fact that you had hesitation and loss of power, I'm thinking it's just a coincidence and has nothing to do with the catch can. It's likely a bad spark plug, bad fuel injector.....something within the engine itself that's affecting the combustion process.

 

 

 

There are a ton of us in here with catch cans of varying makes/models and none that I know of have had any CEL's as a result.

 

Agree, I dont see anyway a can would do that. I thought there was another thread with an issue like this, several people having spark plug wires coming loose at the coil. I would check all 8 at both ends.

My dealership said my catch can wasn't needed and wouldn't catch anything. I opened it in there shop after 2,000 miles and let it run on the floor. Lol

So, I added a second output fitting to my Original RX catch can. I had been emailing with the RevExtreme folks about the benefits of a dual output can, and they were gracious enough to send me the par

Has to be something routed incorrectly or a vacuum leal. If you can post pictures of all your hoses and connections, and the most important is the drain valve being closed (if so equipped).

 

And yes, the Extreme Auto can like this is the cheap China made junk. Anyone with a welded one got one of the originals. These as soon as it freezes out I think we will see plenty popping the glued on bottom and tops off:

Nice! Amazing that these guys have a clear conscience selling crap like that, especially for the price. Have to say elite treats there customers well and has a solid product.

I don't see any evidence on my can that it is glued together at all. Guess I'll just see what happens as the bad weather nears

took to dealer, it was not believed to be related to the catch can...they said they could not find anything stored. Service tech said it could have been a bad fuel or some other small quick issue. I will continue to watch but all is well for now!- Thanks !

There are a lot of opportunities for air leks with a catch can. I was runing worm gear style clamps and noticed that it was distorted a little. Switched to a spring style/factory style clamp and I noticed I had a stronger brake pedal and my MPG went up. so couldn't pinpoint that I had a leak but it ran better when I made sure all fittings were secure/snug.

 

Any "false" air behind the MAF at all is a problem. EFI 101. Could cause all types of mild driveabilty issues. My truck actually ran stronger when I spring clamped all lines and made sure all catch can fitting were properly sealed. Running a cleanside breather and once I re-routed the factory stuff and plugged the ports on the factory inlet tube it ran noticeable better and the brake pedal was strong. which leads me to believe air can get in where you don't want it.

 

To the topic above, if your can leaks, you have an air leak. pretty simple.

Been a while since I've seen that. Haven't driven much in the cold yet. Mine will fill up real fast ...

How many miles did it take to produce that?

3 months and 3,205 miles

 

A little longer than I normally go between draining

Getting back to air leaks....shouldn't you throw a code if the can's connections aren't fully sealed?

If it is a hose and it bounces, it could only loose seal at certain moments on leak more at those moments. Just a thought. Most like that guy had other issues.

 

This week will finally be below 80 here so no more sweating. I'm sure will go back up though.

I guess technically. If you suck in enough unmetered air, some sort of code should be thrown. I've never had an issue tho. All my connections are with screw type clamps too. They are all tight.

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.
