I viewed this as I really didn't want to change what GM designed. I figure their engineers know more than me and if they wanted to add a catch can that they can charge me to empty they'd do it. So I never installed one. This video makes me feel like I should haveWould installing a catch can help and make a big difference??
Yes and no. It'll mitigate the issue, but won't stop it. It seems to just delay the inevitable.Would installing a catch can help and make a big difference??
Basically it's a can that's inbetween the PCV and intake that'll take the oil/gas vapor and trap it in the can to be drained later. There's a few different designs; baffles, steel wool, etc., but the basic chase is trapping and condensing the vapor before it goes back into the intake. All the PCV does is pass along the vapor into the intake, and will build as carbon up along the valves and intake runners on DI motors.Ok I'm not watching a 19 min video on a subject that's been in my industry since forever...
But what is this catch can shit you gheys are talking about
Maybe they're worried about the gas vapor getting into the oil and self immolating? No idea, just a thought.Lmao. Once again we've been doing this for years... We just have a line that drains it back to the crank case.
Have you guys heard about these things called piston cooling jets too?
Yea diesels had that forever toos.

Chemicals can help, but some manufacturers discourage it, as it'll loosen up chunks that could end up going through the engine and or turbo.
Meth injection seems to help prevent. But dual fueling seems to be the best overall solution.
The go to/safest way to clean up existing carboned up runners, is media blasting service.
Next time I drop a scope down my intake, you tell me if that small amount of vapor passing back through are good, especially in the long term...mine were worse than what was shown in the video, and is a common problem on Gen 1 EcoBooost engines, VAG 2.0 turbos, BMW turbo I6’s, and a few others. By building THAT much carbon around the runners and valves, any driveability and emissions gains are completely negated.As to catch cans and what not, there is a common misconception that any oil, vapor or carbon is bad and not wanted. That is actually untrue. A small amount of this is actually GOOD for your engine and emissions/driveability. Think EGR systems, which tend to commonly let oil back into the intake... They do this by recirculating a small portion of exhaust gasses back into the engine, which contain oil, vapor, etc... In this process it reduces nitrogen oxide and can slightly reduce the need for extra fuel to be sprayed on the intake side.
Now if you're dumping your catch can on a daily basis and pouring out 3 quarts of oil and crud, there's a problem. But small amounts, no. You're actually hurting the process trapping it and removing it from the process.
Like I said, it helps, but only delays things. Unless you have a long term way of regularly cleaning the intake runners and valves will start to build up. Depending on the quality of catch can too. Throw a shitty catch can on, and most of the crap is going to get through, put a decent one on, and less will. But some always will and it’s going to build up.There’s a lot of information that would disagree on Camaro6.com
The aftermarket catch can will keep the engine cleaner, longer
But some asshole dealers deny any warranty claims if it’s installed
