CRC GDI Intake Cleaner?

[JerryB52]

Has anyone used this to clean the intake?

After watching many YouTube video's on cleaning the intake, this seems like the easiest...

 

[PMCErnie]

Do you have symptoms that require using this?

Do you have symptoms that require using this?

Some use this product every 10k miles as a preventative measure before symptoms begin to appear.

 

[JerryB52]

Yes, I am using this as regular preventative maintenance...

I haven't used the CRC but I recently used the Seafoam spray intake cleaner. I have about 79000 miles on my R spec and it smoothed out the idle quite a bit and it feels better across the whole rev range. I had the Valvoline intake service done on the car when I first got it at 28000. I have used seafoam on all of my older cars but this was the first time on a newer vehicle. Given the impact it had on driveability I am going to be doing every 10000 from hear on out on i think all my cars.

Also that being said I think I will stick with using the vacuum lines to draw it into the intake vs going the throttle body route. Just seems easier to me vs removing all the damn air intake plastics.

That sounds good. I'm going to use seafoam the next time also. I didn't get a lot of smoke with the CRC. I kind of wanted to see a lot of smoke to show me that was doing something. exactly what vacuum hose can I use so that it doesn't throw a code?

 

[memphiskane]

Not sure on not throwing a code. I used the throttle body version and it threw like 2 codes and a pending code. After starting it back up It kept dying on me when I would come to a stop. I just drove the hell out of it in 2nd and 3rd gear to keep the rpms up for like 20 minutes and it ran like a top after. I didn't get very much smoke with the throttle body method either but I didn't get the whole can in. I may try to redo this weekend properly through the brake booster vacuum hose that way I can get a hot soak as well.

 

[JerryB52]

Sounds good thank you.

Here is what I would suggest. Get a decent borescope - I have a Giraffe borescope I got off Amazon a couple of years ago.

Pull the top of the plenum off (like you are going to replace plugs) and use the borescope to examine the intake valves. At this time you could possibly soak the valves with a good spray if the deposits are not that bad. If bad, then a manual cleaning would be in order (as you've no doubt seen on YouTube).

Be aware that any 'canned' solution to intake deposits may or may not work..or you can make your own (it's not difficult). Depending on the amount of deposits, spraying stuff like this into the intake may be wasting your money without knowing exactly what you're dealing with, which I I'd recommend using a borescope to LOOK at the valves.

Then, if you have not done so, install an oil catchcan to prevent any further buildup of deposits.

As for each brand of solution, look the MSDS for each product to see what's in it and decide.

Is there a post anywhere on the site on how to add a catch-can

100% agree with this. Lots of the Seafoam/CRC type spray manifold cleaners are a mix of diesel fuel and Techron (polyetheramine). Most won't do squat but make smoke if you have any serious buildup.

Walnut shells works. Most sprays don't.

I"m not retired yet. But I feel an intake cleaning comin' on..

Where do you spray it exactly? If you could post a picture of the exact location you spray CRC that would be helpful.

I found a vacuum hose attachment to the plenum that I use a "T" fitting. Off the back of the intake. I don't have a pic, but next time I do it I'll add one. I would LIKE to rig up something where I could just install the can under the hood and have it meter out the cleaning agent whilst driving...

With all the iphones out there could someone post a pic or video of how to use the GDI cleaner via the air filter area or how to access the vacuum line/hose area to use the cleaner? I have an 2014 R Spec Sedan that has a rough idle and would like to try this but I'm not a mechanic so a video overview would be great. Thank you

Have you done a tune up on the car first? How many miles are on it?

I have just over 75K on the car and its been to the dealer for oil changes, trans flush and reset, Radiator flush but no tune up or plugs replaced yet. Maybe just let them do all that and then start the routine after a Dealer Tune Up and plugs? Any protocol recommendations are welcome. Its just a $$ car to take to the dealership.
Thanks
