Results: 7,000 after catch can

[CRF8]

So if I have NO catch can, my engine would be burning the oil instead, right? So why isn't the oil level down in cars without a can?

Those pictures almost look like the same engine before and after a cleaning. I doubt that catch can engines are that clean. I've seen other posts of catch/non-catch can engines and while they show a difference it is not that dramatic. I don't have one but am not for or against. Whenever you can keep your throttle body, intake and valves cleaner that is a good thing. I guess the real argument is how much are they really helping. The amount caught in the can is most likely not the amount that is deposited in your intake. Most of it probably finds it's way into the cylinder and is burned off. I have noticed many dealers offering what they call an upper induction cleaning for 149.95. I'm not sure if this is because they have been seeing problems or just thought of another way to gouge people for un-needed services. I had one done on my wife's 2002 cavalier with 90k on it and all they did was disconnect the throttle body air intake and pour some cleaner into the throttle body while another guy reved up the engine. Some cleaning. I can do that for 10 bucks.

Of all the generations, 5th gen owners seem to be the most succeptable to snake oil and "you get what you pay for" theories. I've seen so much of it and tried to argue it .. then I gave up.

Top tier gas!

If anyone wants proof a catch can "works," just look in the mirror.

Catch cans are a spinoff from the racing community. Most of us don't need them. It's a placebo, something for companies to make/sell, and for bored hobbyists to buy.

Not necessarily. There are some of us who plan on keeping our cars for a long time. 30 years from now when I still have mine, I'd rather not also have 30 years of gunk buildup. I'll GLADLY pay a one time small fee to prevent that.

Your entire premise is based on it actually contributing to getting you through those 30 years, which has serious issues being grounded in reality.

If nothing else I like the way it looks under the hood along with a bunch of other pretty items that cost more then my catch can, and they do nothing but sit there and look pretty, and the funny thing is the hood is shut most of the time so you never see it

You either want one or not, who really gives a S*** at the end of the day anyways?

Buy what you want, enjoy what you have.....

Well said. I'm not sure why so many people waste their time complaining about a mod they don't want.

I get the argument, I'd gladly argue all day about MPG Booster in a Bottle.

I myself bought a catch can, before doing this I purchased some throttle body cleaner, sprayed it in there and get to work.

Other than that, I didn't pay too much attention other than occasionally cleaning out some of the "gunk" that it caught.

Which brings me to a good question. Should I send whatever my catch can catches to that Lab Corp place that reads oil samples that you send in for a fee?

Or should I just drain some oil and do it that way?

You wasted your time, and I guess I wasted my money, I'm just not complaining about it..

Because lots of stuff is being added to the oil, at the same time it is burning a little off.

Even with or without a catch can, an engine will be burning oil. Rings do not scrape cyl walls completely clean, and same with valve seals. They both let a very small amount past.

If cyl walls were scraped completely clean of oil, the engine would be wore out very fast. Every stroke there is a slight amount of oil burn.

All while each night there is condensation. Cold starts there is fuel wash. Combustion by products... all being added to the oil.

Someone that goes 3000 miles and sees zero oil level change, basically just saw the stuff being added approx equalled the burnoff. Now take a long hot highway blast in a car with "full" old oil, and you will see a fast qt burnoff. Because all that heat will burn off the condensates and fuel/combustion by products that have accumulated.

When someone says they have an engine that burns no oil... not really. But it is a good sign it's not excessively burning oil.

I would suggest that everyone with the skills and tools remove their intake manifold. Inspect it and the air pathways to the valves. Take pictures and post them.

If you don't have a catch can you will see significant oil coating the surfaces and coking on the valves. With a catch can you will see much, much less.

Also the dealer sells an "upper induction cleaning" for rough running engines. What does it do? It cleans PCV oil build-up on the intake manifold, air pathways and de-cokes the valves.

Not at all, the car will last 30 years either way, it's just one less (easily avoidable) possible issue and headache to deal with down the road. It's called being preventative. Same goes for the people who don't drive their car in salt. Of course it will last that long regardless, but avoiding salt will also prevent you from having to replace various rusted out parts down the road.

I just put an Elite Catch Can on. It can't hurt, so why not?! Plus it kind of looks cool!
