3.3TT Cleaning the intake valves with CRC

[netwalker]

Has anyone used CRC to clean their intake valves yet? I have been reading about GDI engines and carbon build up and I was wondering. The CRC company says use it every other oil change to keep the carbon at bay.

I'm already running an oil catch can, but was just curious if anyone regularly treats their engine with CRC? I want this thing to continue running like it does for as long as possible!

I did this on my ‘16 Optima once a month:

Highway and go into manual mode. I ran it at 4,000RPM for 2 minutes and put my foot down for 10 seconds. Around 50-90MPH. Repeat a few times. We had the intake tract off for a warranty repair and it looked flawless.

I’ll do the same with the Stinger soon

Very nice, I was thinking at least every other oil change I'd do it. Between that and my baffled OCC I should be able to keep her pretty clean. Appreciate the input Callum!

I'm having no problems putting my foot down.... ....

By any chance were you able to perform this? I am curious as to where you had stuck it through. I read a few forums stating it may damage walls and the turbo if injected incorrectly.

See instructional here I guess... looks foolproof ish

Thanks for the video. I watched this one but was wondering since there are two sides would I need two cans, one on each side?

Maybe alternate to each side after each 30 sec burst, until can is finished.

Love the fact he says multiple times the problem with GDI is "fuel deposits", and that "engine teardown" was the only solution before this product. Also how it improves fuel economy. You would have thought the automotive world would be excited by that..

This is a dumb question but where is the throttle body located? Our vehicle has two sides in which we can spray into so does that mean we must use two cans?

No, we only have one side (one throttle body) and it's on your left if you're standing at the front of the car looking at the engine. The intake manifold for our cars is dead center on top of the engine - spraying this into the intake manifold will treat all 6 cylinders. Remember, you aren't spraying this into your intakes, you're spraying it into the pipe that leads into the intake manifold

Much appreciated for the reply and clarification. So it is on the passenger side. I was going to spray it into the driver side on my next oil change lmao.Hopefully someone will do this and make a video with our vehicles in the near future .

Hm. Through the intake?

*EDIT* Posted this before the prior two posts. It'd be great if someone could diagram this up. I'm wondering how effect this is versus other methods that plug into vacuum lines, etc.

 

[eflyguy]

You can't just open up the intake on the compressed side, and I am certain I would not want to spray this thru a turbo - powerful solvents and high-speed bearings don't usually mix.

I'll wait for evidence of effectiveness before expending much more thought on this. After all, intake valve deposits are a brand new issue and so it makes sense we've never seen much evidence supporting claims by products like this.

Unclamp here and spray it in while the engine is running

Good thoughts being bounced around here.
Opening it up post turbo where brancky depicts shouldn't be an issue as long as the car is still in vacuum as it is being sprayed. If it were into boost then yes, maybe an issue.
So 2000 RPM steady state shouldn't be any problem, 3500 RPM I don't know.

Honestly haven't spent a lot of time under the hood of the stinger yet but on the mazdaspeed platform most people.used the brake booster vac line to ingest seafoam. That car had an maf so opening large vacuum leaks didnt work well. The smaller diameter brake booster allowed the car to continue to idle while you slowly sucked up the seafoam. It was also post turbo so no seafoam went though there.

All that said I think the overall consensus was that seafoam or similar treatments to remove deposits was likely just not very effective. Perhaps if started from the beginning d applied frequently it may help but really the only sure way was removing g the manifold and media blasting the valves

Thanks for that picture. Helps a lot. Will be putting it through there on the next oil change. I had thought it would have gone through the intakes from the videos. I was surely wrong lmao

Stinger generates significant boost at 2k RPM. That's why it's such an awesome engine to begin with.

That said, I anxiously await the amazing results to be reported back here, as I'm sure do the recent multitudes of GDI owners..

um, no.
you take off a hose downstream from there and squirt inside that hose.
i have done this, not guessing.
look on youtube there are videos on using this.
