Dumb Question, but Why install a catchcan? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

ctk1 · 01-07-2011, 03:51 PM

Sorry guys, I've noticed all of the catchcan topics lately. I must have missed something somewhere. Is there a known issue with these cars that has resulted in everyone installing catch cans? I did a quick search but there are way too many threads. I just want to be sure that I'm not missing anything important. Thanks guys.

Catch cans are just a good way to keep recycled oil out of the intake...

PCV system routes oil vapor back into the engine's intake for emissions reasons.

The catch can collects that so it doesn't get into the intake, which overtime will reduce performance and gunk up the intake.

[SSMike]If you do a search you'll find quite a bit of information on catch cans. Basically it goes in line with the PCV system to condense out any oil vapor before it enters the intake manifold. The condensed oil fills the can and you can periodically drain it out. This improves performance under WOT conditions because no oil will mix into the combustion chambers. Therefore it reduces spark knock and keeps the internals cleaner! Hope this helps.

Hope this helps man i was asking the same thing.

Thanks GTAHVIT! I appreciate it. I just saw all of the attention that they have been getting and wanted to make sure I wasn't missing and issue with these cars.

I wouldn't mess with it if I were you. If the design engineers didn't put the catch can into the engine, there must be a reason why. I haven't seen a single production car that has a catch can. Any Mechanical Engineer know why?

My understanding is the reason they don't use catch cans is the emisions laws requie the vapor to be recycled back into the engine.

Unfortuantely it will cause the intake to be coated with oil. eventually it will hurt performance.

The OP should do a search and read why a catch can should be installed. There are several threads on here to explain their benefit. Some cars will collect more than others, but it's a worthwhile mod for sure.

I still don't understand why burnning vapor oil would be good for emissions? A catch can that catch vapor oil without burning it would make more sense of promoting good emissions. Is burning vapor oil not creating any kind of smog or ordor or I'm over analyzing?

Yeah, It seems that would accomplish the exact opposite of what emmissions regulations are trying for.

I think the idea is the majority of it gets burned off the second time through instead of being sent out the exhaust..

But at this point you'd need one of the experts to chime in here.

That is about as much as I know.

Found the link for you. Long readings and I hope you understand a lot of technical write up.

I believe the writter is also selling catch cans. Use your judgement, it's your money my friend.

Beyond performance reduction. Oil vapors can cause the computer to adjust timing due to stoich and could lead to detonation. Believe us that have proper working cans when we say you do not want this stuff mixed in with your fuel charge.. You only want fuel! Not as big of deal on non SC cars because much less blow by but still a very very good idea.
