Just finished up the install for my AddW1 oil catch cans. Install was fairly easy they now have the mounting brackets designed for the K5. They're even planning to use my install photos for the official installation guide!

If you don't mind me asking, what region are you located and have you considered variation in climate affecting the catch can system? It will soon be winter and I've heard recommendations from others to remove the catch cans whenever you're in a sub freezing temperature

Pardon my ignorance, but the pcv valve port doesn't look like one I've ever seen. It looks like it uses a HUGE hose and goes to the back of the engine, rather than to the intake manifold. I have the same engine in my 2022 Hyundai Tucson hybrid and want to install an oil catch can. Can anyone assure me this is the correct setup for the pcv valve, as I do not even see the valve at this location. Thanks!

I'm not sure if the hybrids have the same 1.6T engine as the gas-only cars, like the Hyundai Sonata and the Kia K5. Remember that while they may both be a 1.6T engine, they may be different in design and/or layout to accomodate the hybrid system.

Here's a video of someone delving into the parts of the Sonata's 1.6T engine (same engine as the Kia K5) for reference:

It's exactly the same 1.6L Turbo engine as the K5 and Sonata. I just haven't ever seen a PCV valve setup like this. Suspect it has to do with the gases going into the turbo. Thanks!

I wasn't sure if they changed the engine to the newer 1.6T for the '22 hybrid models, but good to know that it's the same one!

The older 1.6T engines had the PCV more towards the front but the newer ones are routed more behind the engine, with the CCV towards the front instead.

The turbo is also behind the engine with it's own little heat shield, which I found funny. 😂

if GDI engines are designed with this flaw, why dont they already come with the engine? I would think the engineers know about this and design the engine to run properly without the cans..

It's all really to make the engines meet stricter emissions standards. Part of the exhaust is recirculated in order to get burned again more completely. Manufacturers are also prohibited to installed an oil catch can from factory as that would be considered a "cheat" device that modifies the exhaust system.

Without one, it is therefore recommended to do a regular intake and throttle body cleaning maintenance, especially so for GDI engines.

So I read on another post that with catch cans there is an oil smell that hangs around. Have you had any issues with a oil smell post-install?

@OP, what have you caught in the cans since install? I've heard that only the PCV can catches oil and that the CCV really doesn't. Wondering what your experience has been.

I only have the PCV line installed with a catch can. The can filled up with mostly water but some oil at the bottom after a 500 mile drive. I used the 15 mm. fittings. There is no oil smell. I would suggest checking the dipstick at every fuel fill-up. To me, this is the single most important add-on to prevent carboning up the valve stems and valve edges.
