No pics of the back side valves?

I only know of two options, Mighty Mouse and Elite Engineering. The major difference between them is that the MM can has the ability to vent externally while the EE can is more like the OEM setup as it is a closed system and does not vent. IMHO, the MM can is more conducive to higher boost/"drag" setups.

MM makes no claim as to how much it captures while Elite claims to remove 90-95%(?) of the problem. Neither will completely eliminate the problem but, both 'should' greatly reduce/slow the long term build-up of carbon/coking on the intake side.

I say 'should' because until we start to see more of these motors hit the 30-40K mile range, it is unknown how much carbon fouling the LT4 is going to produce. There's a lot of anecdotal evidence flying around right now with just a handful of examples going both ways. Ultimately, time will tell.

Same here.

For you guys that have tried the CRC method, how are you applying the stuff? Doesn't running the engine with no air filter and/or MAF sensor in place throw codes? Thinking about this for my 38k mile Terrain.

no codes. try to spray AFTER the MAF.

That's a pretty big chunk-o-nothin'good on the valve at the base of the stem. I saw you posted in a NOS thread, was your car modded at all?

Brightened up the photo a bit...

Only mods are ported blower snout, 95mm TB, and CAI. I took the photos when the blower was off for snout porting.

I loosened the hose clamp past the MAF and snaked the straw that comes on the CRC can toward the TB keeping the air box and MAF attached. No codes and no issues.

I would have to imagine more of the product goes towards the front cylinders than the rear using this method? No concerns with breaking a whole chunk of carbon free (if it's really coked up) and sending it through the motor?

The blower will disperse the chemical evenly.... hopefully there isn’t enough carbon build up to worry about your second concern. Obviously can’t say for certain. I’m going to try it.

Not to open a can of worms, but which engine break-in method did you use?

FWIW I beat the shit out of mine from the get-go and it hasn't used an ounce (that I can tell) in about 1200 miles.

Service guy told me today that Chevy has a service they offer to clean the carbon build up and it's recommended to LT4 owners at 45k miles.

Of course they do. One more service they can offer you and one more reason they tell you not to be concerned with the carbon build up.

I wonder how much the service is.

By the way, I see you traded in the 2018?
