Hey. I've been reading up a lot on catch cans and was considering throwing a mishimoto or elite on my 2016 SS. The car is already at 15K mi. though so I'm wondering if it's necessary for me to clean my intake valves first before throwing on the catch can or what the best options are?

I'm also not very familiar with the best way to clean the intake valves. Any tips to make this easier on myself if I move forward with it? Thanks in advance!

I wouldn't worry about it. Just throw one on and enjoy!

CRC makes a product you spray thru the throttle body with the engine running. I would spray a can thru it and put the catch can on.

Thanks Fellas. I'm trying gauge if I can just avoid doing the cleaning all together and just throw the catch can on (I went with Mishimoto because of the apparent ease of installation) and stop the build up moving forward. I imagine when it enters high mileage territory, that minor build up it's had up to 15K shouldn't be too big of an issue right? I'm just a bit nervous to put in chemicals through the engine if I don't have to..

I would just put it on if you want peace of mind. I'm not a sold on them we have a factory one maybe not as thorough, but I'm a believer in driving your vehicles "some rpm" keep the carbon clear from everything

It should be fine at 15K. The higher mileage examples that I've seen posted on this forum have very little build-up (even without catch cans). These engines don't appear to have issues anywhere near as bad as BMW and others.

you are not understanding the issue with DI. RPM will do nothing for keeping oil out of the intake manifold and building up on the back side of the valves. The issue is intake side not combustion chamber. This was not as big of issue on port fuelinjection because you had fuel being injected directly into the intake ports which helped keep build up off the back side of the valve. DI injects fuel directly into the combustion chamber, so nothing but air and oil vapor hits the intake ports and back side of the valves on these motors. I don't think it's as big of issue as the internet makes it out to be, but a catch can does help reduce oil vapor entering the intake manifold and it would not hurt to spray some crc cleaner in regular intervals to help keep the back side of the valves cleaner.

I'm a bit nervous about running the CRC cleaner at 15K because I was reading that the buildup is a hard crystalline and if it happens to break off, it wouldn't be much good for the engine. Anyone have experience using CRC at 15K or later without issues or have tips? Either way, I'm going to throw on the catch can as soon as it arrives to help where it can. I wish Elite catch cans had better installation instructions available online, I couldn't find anything clear on it whatsoever. Way to shoot a good product in the foot.

I might avoid the risk and just put the can on then unless I get a strong voice from the forum otherwise. Thanks for that!

Nope it softens it...aside from that you don't have enough mileage on the engine for that to be a issue. There is a thread in the maintenance section discussing this.

Yeah, you would think with the freaking essay like response Elite gives on here to some questions they might actually be able to write good instructions. Hence why I chose Mighty Mouse Wild.

Spray it in where? There's no conventional intake manifold, right? (forgive my ignorance please)
