Catch cans
- Thread starter GligorovKia
- Start date
If you follow basic maintenance, use top tier gas, and do not untune your car pass manufacture settings, there is zero reasons to add a catch can. If you do add a catch can, please make sure that the catch can manufacture will warranty the destruction of your engine, I have not found one company that will, because when your engine dies, it will most likely be the catch cans caused it. With out proper vapor lock, you are actually sucking in water vapor into your oil, making everything worst.
Think about this one for a second. Kia offers a 100,000 mile warranty on their engines. If a catch can was really needed would then not spend the 100 dollars in adding one to the car rather then dealing with the warranty problems?
They don't because most people will do proper oil changes, most people will not untune their engines, and most people will use top tier gas. You do those things, nothing will build up anywhere.
Now if you are drag racing want to untune your engine for some reason, then you probably should get a catch can, but warning, you will shorten your engine life doing so. Modern engines are not built for catch cans, if they where, then they would have been added by the manufacture.
Warning rough language. Not adult, but rough.

Thank you for your reply.
i have catch cans on my pick up trucks and it has 2 chambers that filters almost everything and its enclosed system and i drain it every 3k miles.
the crap thats collected in the bottom, the whole things was going to be burned inside the engine.
and its not just blow by oil, all the moisture and other crappy things, they all stay in the catch can.
why would you think that a catch can will destroy an engine? its just adding an extra filter.
and i am not talking about the cheap catch cans that are just straight thru design.
and yes,the vehicle will be going to dealer for maintenance.
when you are saying top tier gasoline, you talking about 91+ octane ??? owner manual say you use regular gasoline.

In short? Catch cans add a level of complexity to a already complex system. Complexity is the enemy of durability. Your engine be was designed to run as they made it. If a can was needed they would have added it. Adding the can is undoing that design. Small things can create large problems like the failure of a vacuum seal.
Catch cans fix a problem that only exists in a very few limited cases.
Continue reading the manual on gas it will get to top tier. Basically it is group of distrubators that add enough detergents and other chemicals to help stop things like carbon build up. Google top tier gas for the list. It has nothing to do with octane.

The gasoline never hits the top of the intake valves in the Telluride GDI engine so I don't think the detergents will help clean the valves. So I think the discussion of catch can's has some merit.
Another option is periodically using CRC intake valve cleaner. But I'm wondering if anyone here has tried that product.

If I'm clear on my understanding of the GDI Atkinson cycle engine, the intake valve remains open for about 1/3rd of the compression stroke, thereby pushing an air fuel mixture back over the intake valve and into the intake. This should allow for detergent additives to do their job, hence the need/recommendation for top tier gas. Think we are good on this, no need for catch cans or intake valve cleaners....
The Atkinson cycle delays the intake valve’s closing until the piston has completed 20 to 30 percent of its upward travel on the compression stroke. As a result, some of the fresh charge is driven back into the intake manifold by the rising piston so the cylinder is never completely filled ... https://www.caranddriver.com/news/a...stion-cycle-and-what-are-its-benefits/..looks like you're both right.lol
