We've had our 2020 Soul for about a month. Time to modify it.

This weekend I decided it was too damn muggy to do Forest’s back brakes so instead I put a catch can in Punkin Spice.

This is what I started with. Green is the PCV which I will interrupt with the catch can. Pink is the crankcase vent into the intake which I will run down the back side of the engine to vent into atmosphere and blue is where I’ll mount the can.

Here is what I started with. The hose I got with the kit was much nicer than the blue crap they gave me last time and it even is orange like the car.

Modified the bracket with the kit to hold the can better and to fit in the spot I’ve chosen for the can.

Removed the intake hose and swapped the stock hoses to fit where the can is going better.

Can in place. Final routing of hoses from PCV .

Final routing of crankcase vent.

Plug where crankcase used to vent.

Here are the tools I used and what was leftover after installation.

Complete and put all back together .

You mean you tore that factory intake out to install a catch can and you didn’t install a cold air intake too?

Da fuq is wrong wit chu?

Nice job! Kinda looks like it would be difficult to empty, no?

Because the vast majority of modern intakes are not a limiting factor of power.

On performance oriented vehicles this may ring true.

On economy cars like this, they always have been, and looking at this design, they still are.

But the vast majority of aftermarket  intakes add no power, and sometimes even take away. At best you add a bit of noise, at worst you are literally sucking in more debris and fluids. In the middle of those two is sucking in hot air.

Again, this severely depends on vehicle and the factory intake design. One cannot make a blanket statement saying it doesn’t work for every vehicle when in fact, quite the opposite is true.

Many economy cars net great gains from simple mods, they’re tuned to be quiet/reliable from factory, so simply opening them up can net amazing gains.

Many economy car’s factory intake design sits them directly over hot exhaust manifolds or right against the radiator as well, with no heat shielding, so the Hot Air argument goes out the window if one runs their intake behind a headlight or somewhere it has a chance at less than engine bay temp air.

Would it not be easy to tell? My Volvo and lots of newer cars I have looked at suck air from the front of the grill/the front of the hood. I would think it would be easy to tell if the routing sucks?

Yeah I really would like the car to breathe in more particulates!

I don't want any of that.

I can attest to this. Ford, in its infinite wisdom, installed a “lifetime” air filter in 2005 - 2007 Focus’. They are not, lifetime. I went with a YouTube cheat and my car runs a heck of a lot better, with about a 2-4 MPG gain.

It’s no t super easy no but I shouldn't need to empty it often. On our older Soul (The Toaster) I only check on the catch can every other oil change. That 1.6 spits out a ton of oil. I can empty the can by taking out two allen bolts and one 10mm

it has little to do with the routing, or shape of the ducts. Kia’s specs say the engine produced peak power at 6,200 RPM, which for a 2.0 liter engine means it needs 219 cfm of airflow. that ductwork is more than sufficient to deliver that.

You can probably gain even more by eliminating that convoluted tubing and making all the piping match the largest diameter.

The neck down leaving the filter is sapping flow/volume and the convoluted tubing kills flow as well.

Factory filters aren’t as efficient as some people would have you believe. Most quality aftermarkets flow better while removing more particulates.

1. Convoluted tubing kills flow, so anything with it is not flowing as well as it could be.

2. Making your airflow do a 180 from where it’s pulled from to go into the filter is never a good design, again killing flow and adding turbulence.

Did you even look at that design?

Terrible routing, convoluted tubing everywhere, that thing is just sucking power trying to suck air through it!

What do those engineers know? Amirite?

You know the PCV sucks fumes into the manifold, and fresh air is drawn in from the other pipe, right? If you disconnect the ‘purple crankcase vent’ from the fresh air intake and lay it behind the engine to the ‘atmosphere’, you will be drawing dirty road grime air from behind the engine into the valve cover . At least put a filter on it. Or hook it up back to the air intake pipe. This motor is port injected, not GDI, so a catch can in the PCV line does very little, as the valves will be self cleaned by the injectors. On a GDI motor there is good reason to keep oil mist out of the manifold.

I did no t realize it breathed in through the other pipe, and how do you know this 2.0 is not GDI? 

PBeng > CalzoneGolem 08/20/2019 at 12:49

Because you can see the fuel rail and injectors on top of the manifold. It also doesn't have big GDI logo.

PBeng > CalzoneGolem 08/20/2019 at 12:54

Ad the fuel rail has a sticker that says MPI (multi-port inject)

Fair enough. I’ll keep the can but hook the other part back to the intake.
