Valve/Carbon Cleaner for the 2.0T

[west tex]

Have any of you had any experience using this spray-in compound to remove excess carbon on the valves/combustion chambers?

The stuff gets lots of good online reviews. And our GDI engines seem to be prone to carbon build up.

Are these 2.0s experiencing excessive carbon buildup? I haven't really seen any posts or pictures of it like I have on other vehicles.

The GDI system doesn't allow the gasoline detergents to clean the valves, so it it's a concern. Some say that oil catch cans are a solution, while in extreme cases, walnut blasting is a sort of last resort.

My question is whether occasional use (each 15K miles, for example) of a product like this might address the issue.

Yes, some DI motors are much worse than others though. Early DI designs had really bad issues with it. On my 2017 VW, that 2.0 was pretty bad with it and it was a well known issue with that engine. I haven't seen anything like that at all on the FCA 2.0L so that's why I asked if you've seen evidence that this engine is particularly badly affected by it.

Have you looked at the valves? Are they dirty?

IME, water works as well as anything else. A small amount of water, injected into the inlet, kept my turbo engines of yesteryear very clean. I used an old style oil pressure idiot light sensor (1/8 or 1/4 NPT) to tap into the manifold. When the boost hit a few PSI, the sensor would turn on the winshield washer pump and a small (#50 drill IIRC) orifice sprayed water into the intake manifold. You could rig up a removeable temporary installed small winshield washer tank like this.

At what mileage did you start getting misfire codes?

Between here and the Giulia 2.0 forums, I’ve not heard of a buildup issue. The Giulia has a built in oil separator in the cam cover so I suspect the same for the Jeep 2.0 although it is a different cylinder head. Run tier 1 fuels, get on it once in a while, run the correct oil specified for this DI engine, and you should be good to go.

The 2.0T does have an oil separator. Mine was leaking and replaced under warranty. From the description provided by the service advisor, it's on the passenger side of the back of the engine.

I wanted to use the product, but I had no idea how I'd go about safely injecting a stream without hitting any sensors or causing any unintended consequences. It's too bad. If there was a simple port I could spray it in, I'd use it in a heartbeat.

Thanks for confirming what I suspected!

Don't know how good the CRC product is, but Seafoam works well. Helps clean the intake manifold runners and the back of the intake valves.

Would you happen to know the part number of the oil separator that you could share? Thanks!

If I were to go to all this trouble, why not just buy a water/methanol kit? Not only do you get clean valves, you get more knock resistance, cooler intake temps, and more power. The power gain would be minimal without a tuner, but there a guy on the JB4 forum with some very impressive dyno numbers adding water/meth and boost. 333 wheel hp and 470 ft-lbs is pretty damn impressive from a mostly stock 2.0t.

I've thought about doing that myself, more worried I could potentially jack something up doing it though. Berger does the water/meth kits as well right?
