Catch Can

[Iqoniq]

Is there a good reason to buy the catch cans out there for this car, instead of building my own for a fraction of the price?

No

There is a good reason to run a catch can. How you get there is irrelevant.

No sure what you mean about building for a fraction of the price. I bought a universal baffled one for around $30, bought braided line for about $15 and ran it, it even has a drain valve on the bottom so i don't have to unscrew anything. But if you can make one for less than that go for it!

Yes, most are plug and play and actually work better then piecing one together. However, if you want to save money, then go for it. I honestly will pay more for a proven product that looks stock, uses the correct fittings, and works great. That is just me however.

Hi, I just joined a month ago and live in the Atlanta area. I have 2016 non PP SHO that I think is just grand. Am learning a lot in this forum about maintenance and getting ready to change the oil with the recommended viscosities of Red Line Oil soon. However, WTH is a 'Catch Can'? Thanks.

Livernois even said no up until 2018 or so until they started selling their over priced one. Not sure on why they changed their minds unless they just wanted to jump on that cash cow. Better off running a can of crc turbo intake valve cleaner at every oil change. I tried a few different brands of good carb cleaner and seaform when i had the intake manifold off on my first engine. Crc worked better then them all combined right before my eyes just on contact.

Why you need a catch can, and yes you need one. All FI engines should have one regardless of fuel injection type.

Start by getting a $15 endoscope off ebay/Amazon. Pop off the MAP sensor and slide it in. You might find your valves are very clean without a catch can. (Mine looked great at 50k miles)

That isn't always the case.

That isn't always the case.

Gonna have go with this comment, even if the valves "look good" you're still dealing with blowby, why burn that and lose a little power/efficiency (small i know) when you can catch it and dump it every couple weeks. If you're lazy like me, run a drain line so all you have to do it turn a valve vs unscrew the tank.

Last I heard, out of tank fuel system cleaners weren't really safe for our engines, something about the extra combustibles causing the turbos to overheat, is that no longer the case? I've wanted to do a valve cleaning for a while, but avoided it for that reason.

That isn't always the case.

Which is exactly why I said to look at the valves. Why assume there is a problem and spend hundreds of unneeded money? The $15 dollars is well spent since you will find many other uses for the endoscope. No need to fix problems you don't have.

I put a stupid nice UPR catch can on mine with the clean side separator along with upgraded check valves...

Every 3K miles open it up... I have never had more than a table spoon of oil/water...

That being said, even before the catch can the cars induction system was always stupid clean.

And I pull 2 to 3 ounces of crap out of mine every 3k miles. Guess you guys have unicorns. Subietech just had his intake off and his valves were gunked up.

Please don’t think I’m arguing your personal experience but I had to start emptying mine at 1,500 to a maximum of 2,000 miles. My can would overflow if I waited any longer. It spills out the side half the time on the way to the bench because it’s so full. By volume probably 3-4 oz of water, 1-2 oz of emulsified oil and water, and another ounce of straight oil.

Oh I’m not thinking your starting an argument lol! I have seen sooo many different results on these motors... some people never had a problem with it... others are emptying all the time...

Glad you are diligent in maintaining it!

They do make universal catch cans that evaporate the contents so you never have to dump em.. might be something to look into.

Hi, now I understand what and why a Catch Can is needed. I just ordered one on Amazon that actually includes a dipstick to check the level of oil without unscrewing the canister. Thanks for the tip.

It’s far worse in the cold weather. I don’t get nearly the amount of water during the summer months.
