From what I've read so far, they filter out a bunch of nasty shit and the only reason manufacturers dont include them is because people will forget to drain them, So why are they so uncommon? should I not get one?
They're uncommon because people will forget to drain them.
Kayden Garcia
Get an AOS and never have to worry about emptying it is my advice.
Blake Ortiz
What is ofc system?
Only time a catch can is needed is on a high FI motor which intentionally has higher ring to cylinder wall clearance
Cameron Adams
Pcv...Damn mobile autocorrect
Ethan Nelson
Can any engine have a catch can installed or only turbos? I want my K1G engine to be inmortal
Tyler Brown
Because you're piston rings are fucking junk if you have enough blow to actually need one of these. Modern diesel engines use crankcase filters which perform a similar task, but is entirely unecessary on a properly operating 4 stroke engine.
Nicholas Harris
dont catch cans release a bit of oil mist into your engine bay?
fuck that shit.
Parker Thompson
if you think blow by is the only reason oil gets sucked into the intake on a modern car you're a fucking idiot. Fitting you drive a mustang.
Colton Anderson
Nah a proper catch can should exhaust back into the intake.
Joseph Myers
I think the problem with them is removing the pcv valve and venting your crank case to atmosphere. Some states are communist.
Dominic Martinez
Because people forget to drain them
Jaxson Phillips
Brings up a fault code and check engine light.
Ethan White
Why not just install something similar to an air separator with a filter in it? >pic related is normal install >for auto usage, reverse inlet and outlet Oil and whatnot would be caught in the strainer, clean air gets sucked back into the intake.
Nathan Collins
You're retarded.
Lucas Myers
because they're pointless
Lucas Russell
You're fucking stupid lmao. All cars get blow by it doesn't matter if your rings and bore are brand new and gapless you still get blow by and positive crankcase pressure.
Nicholas Nelson
>removing pcv recirc >pointless >not getting oil all over your engine bay >pointless hmm
Nathaniel Sanchez
I've never had any problems running my vehicles without one
shit is snake oil
Robert Hall
You only need one if your crank case pressure is higher than stock, like a high hp na or turbo/supercharged.
Julian Hernandez
You have a pcv recirc. it's an emissions thing. it coats your intake with oil and replaces oxygen with inert gas. removing it gives you power and just generally removes a headache using a catch can when you remove it stops oil from getting in your bay.
you not understanding the point doesn't mean it's pointless.
Blake Edwards
so what if a little oil get in the intake? modern cars are designed to deal with it
its a waste of money, good job falling for it
Caleb Ward
We don't all drive stock toyota camrys to and from school and work exclusively you fucking casual normie faggot.
>i dont understand something >must be snake oil kill yourself.
Ryder Young
I'm sure that MAF and TB could enjoy a good lubricating, right?
John Wright
pcv dumps into the intake behind the tb
Owen Green
From factory it's an additional service item, not worth it. But you can do it yourself for cheap.
If done properly, there's no downside to having one, you'll get a slightly cleaner ait/fluel mixture, and you won't have to clean your intake system as often.
Just don't fall for the 100$ kits, most are just rebranded ching chong crap you can find for 15$ on ebay.
Because you can find a million cars with 300,000+ miles on the roads, including direct injected cars (the only time you could possibly have an argument for a catch can) and only a small handful will have catch cans, if any. If you're going for a full retard tune and don't want your engine to last anyway, you might get it to last 5% longer with a catch can.
I've heard "RX" cans destroy a lot of peoples' engines.
Parker Hill
my car has a map oil catch can, the person who built the engine just put a tube from the drain plug on the bottom to the ground
Joshua Ross
Retards like you are going to make vehicle emissions/equipment/safety inspections required across the country.
Jacob Lopez
emissions and equipment saftey inspection are required in my state, but i passed
so that means your civic with the axle back exhaust and intake will be fine
Ryder Moore
Because I can just plug the hole in the intake and let that fuckin hose hang like Christ intended.
Kayden James
There's also oil leakage on the valve stems that contribute to the carbon formed at the intake valve of direct injection engines.
Jason Sanchez
You are wrong. Emissions are required in your county. Source: I live in Franklin county and we don't get inspections cause we're not a shithole like cleveland
Mason Green
>so what if a little oil get in the intake? modern cars are designed to deal with it Direct Injection engines are not designed to deal with it. The oil carbonizes on the hot intake valve and never gets cleaned off. In older fuel injection engines, fuel mist does appear on the intake valve and thus the detergents clean the intake valve.
Direct injection engines have an injector for each cylinder that puts the fuel directly into the cylinder. It is not injected into the air stream outside the cylinder. Toyota and other car manufacturers are going backwards a little to fix the problem by having both direct injectors and another set of injectors put some fuel on the intake valve.
That's why "top tier" gasoline doesn't do much for cars that are direct injection. It does work for cars that have throttle bodies or cars with injectors outside the cylinder.
Robert Thompson
if you think two high speed sliding separate piece of metals will never leak air, you are dumb.
Austin Diaz
can you not fucking read retard
also franklin county is shit thats why they have no stadiums, no casino, no lake, no tourism, no industry, very vew colleges, no bar scene, no nightlife, and propery values and costs that are half of cuyahoga county
John Gray
>Why doesn't everyone install oil catch cans?
Because for consumer cars, detergent gasolines clean the intake valve adequately especially if it is top tier gasoline. It's only direct injection users that avoid having an intake valve cleaning by installing a catch can.
If you have your dealer do an intake valve cleaning for $350 or more, it is basically much like:
This man is correct. DI cars can benefit from catch cans because it will slow oil residue buildup in the head. YMMV from car to car though.
Tyler Ward
Mine has both.
Jeremiah Murphy
Mine dumps into the air filter inlet in front of the turbo so it can go into my intercooler, charge pipes, tb, sensors and coat the intake manifold and my ports/ valves.
Logan Baker
Nah that only applies to people who baby DI cars
I take my DI shitbox very near redline every time I drive it.
The Italian tune-up isn't a meme for direct injection
Jeremiah Morales
Enjoy your condensation forming in there. The first time you empty it you will shit the bed thinking you've blown a head gasket.
Nathan Richardson
-9001/10
Colton Turner
>The Italian tune-up isn't a meme for direct injection Italian engines are different from your usa engines.
Jose Diaz
just bought pic related, gonna fill it with steel wool.
Joseph Cook
>Why doesn't everyone install oil catch cans? There's no place to mount one unless it is far away. How long can the tubing be?
Jeremiah Bailey
pretty long
Joseph Fisher
5th Gen Camaro 1LE has a factory installed catch can.
Benjamin Foster
mines long as shit. vents back into the valve cover on the driver side. I also have friends with catch cans installed on a Hemi Ram, F150 5.0L and F150 2.7L. all installed with the vehicle being less than a year old and they're plenty effective. with my truck I used to get a nice puff of black smoke when I laid into it hard after driving normally for a while but I don't get that anymore with the catch can installed.
Luis Flores
How often does it need to be emptied?
If I forget to empty it in the nick of time, what bad things would happen?
