Catch Cans

[DonD]

I'll admit that I've been skeptical about catch cans, lots of aftermarket products promise more than they deliver. I've mentioned it in other posts, I had a 2016 Chevy SS with the Corvette LS3 engine that was destroyed by an uninsured motorist, totally his fault said the police officer who observed it and cited him. The SS forum talked of catch cans.

My car is a 2022 Stinger GT1 and of course a lot of posts on here about catch cans.

I know the service manager at the local Buick/GMC dealership. He's not a paperpusher, he's an experienced, certified mechanic in his own right. I just called him and asked about catch cans. He recently bought an earlier high performance Camaro with the earlier blower engine, a little below 600HP. He said a catch can was the first thing he did to the car and highly recommended them. That cinched it for me

So, I'm in the market for a catch can. He bought a Moroso can that was set up for his engine.

Recommendations as to what brand for the 3.3L TT would be appreciated. Don

Mishimoto, works and super easy to install.

It seems like alot of the offerings for the Stinger are pretty similar. There arent really any fancy offerings like the Cobb air oil separators for Subies, etc... I went with JLT for ease of install and supporting a U.S. company. Mishimoto, ADDW1, BMS are some others to name a few. They all will perform similarly from what I've seen.

Plus 1 for the Mishimoto.

A couple of notes.
On the 2022 3.3 TT (what I have), the stud on the inner fender is no longer there. But there is the hole for it. As I recall, I used a 5/16 x 1/2 inch long self-tapping screw for the lower bracket mount.

The hose clamp on the PCV is a real bear to get a pair of pliers on. I wound up taking the engine cover off and then working the clamp around until the clamp ears were vertical, at which point that clamp was easily removed.

Looked on Amazon, several varieties of Mishimoto. Can you give me a model #? Thanks, Don

I went with ADDW1 for my 22 GT1. They usually include hardware because we don't have the stud like others do. They forgot on mine and were going to send the hardware but I asked for $5 refund so I can just buy the screw, washers, and locknut on my own. Prices weren't bad and it looks good BUT you will have to modify the dipstick because it stood too tall and was leaving an impression in my hood insulation. Seems like a lot of work that they should have figured out but I think it was a good choice!

Catch cans are definitely a useful part in these engines and become even more of a critical component when you start to modify/tune the vehicle. I often recommend the Add W1 Twin Can Kit to 3.3T owners (click HERE to view). However, there are many other great options that we carry (click HERE). Feel free to reach out if you have additional questions or if you need a discount on your order!

Got mine here.

Kia Stinger 3.3T - Mishimoto Direct Fit Oil Catch Can

Reduce carbon build up in your Kia Stinger 3.3T engine with the Mishimoto Oil Catch Can. This catch can system is installed on the PVC side of the engine. Mishimoto uses a unique design trapping particles with a 50-micron filter instead of draining back into the oil pan of your vehicle. Quick...

I went with the dual can set-up from Sxthelement. SXTH Element Engineering

Had I do to it again, I would have only gone with the single can. So far, the other side (drivers) doesn't catch anything; just vapor coating the inside of the can. That might change with wear and time, driver habits? Who knows. Might disconnect the 2nd can at some point. We'll see.

Sxthelement is not the cheapest out there, but I liked their precision machining and good reviews (other than cost). Since my plan is to keep this car for a long time, I didn't really look at cost so much as a factor. Their kit went on very smooth and no issues or modifications necessary. There are others out there though that I'm sure are just as good.

I'm assuming those with the 2.0T/2.5T engines would benefit, also only 1 needed as well. I will eventually get around to "boosting" output on my 2.5T.

+1 for the Mishimoto catch can

Yes, it will benefit all models of stingers.

The boosted intake pressures from turbochargers (and supercharges) also cause an increase in crankcase pressures. The stock pcv system vents these pressures but in the processes allows oil and other contaminants to vent back into the the intake of the engine.
The catch can catches said contaminants before they get sucked back through the intercooler, throttle body, and engine.

It is even more desired on GDI (gas direct injection) engines. This is because in GDI engines the injectors are after the cylinder head, and thus fuel injector treatments don't really do anything to remove carbon deposits on the valves (caused partially from said oil oil/contaminates).

Here is a pic of mine on my 2019 GT. It is a little dusty.

 

[SIMONGUEY]

part of me feels like i installed mine incorrectly but have no idea how to figure out if i did or didn't

That cinched it for me

There's two schools of thought when it comes to maintaining direct injection engines over a longish period of time...

1) Prevent the buildup on the back of the valves [catch can and/or regular interval chemical cleaning]
2) Deal with the buildup on the back of the valves later/when it becomes an issue

I don't think there's necessarily a better choice between the two, just different ways of addressing the issue.

I'm personally just looking at doing #2 at 50,000+ miles or when I'm noticing any changes in engine output (rough idle, hesitation, lack of power, etc). I suspect I'd be able to go much longer than 50,000 miles before symptoms related to DI buildup manifest. I'll be pursuing paying a shop to walnut blast the valves clean. This assumes I have the car at the time, which isn't a guarantee since I'm putting les than 15,000 miles /year on the car right now with no significant changes in use planned.

If I tracked the car or drove super aggressive, I'd probably go for a catch can. The only issue I have with catch can use is raising red flags should I need warranty work. I know I know... they have to prove it's directly related to the failure, but while I'm squabbling with them in court for 2 years without a car I think I would regret the catch can. So, I hedge my bets and just budget for the cost of dealing with the issue later.

i will post some later today.

Emailed Daniel at the K8 store, no response so far.

Amazon says the direct fit Mishimoto doesn't fit the 2022 GT1, why I have no idea, don't think there are major changes between the two or are there?

Would prefer to buy from a forum sponsor.

Talked to the local dealer's service manager a few minutes ago, he strongly recommends catch cans. Good to hear. Don

Like mentioned earlier, you will need additional hardware if the catch can uses the stud that was in the previous years. If mounted by the strut brace hardware, it should be fine. I know the ADDW1 will work as long as you tell them you have a 2022. Someone of the forum is selling theirs, I believe.

 

[DonD]

Just ordered the twin can setup from K8Stinger Store.

They said that Amazon was correct in saying the Mishimoto direct fit system didn't fit the 2022 GT1.

I appreciate the assistance from forum members. Don
