CRC intake valve cleaner

[u/_slightbuzzingsound]

I heard some good things so I picked up a can, but I never do anything I don’t want know about to my car without YouTube and Reddit community’s. Every YouTube video I’ve watched made little difference with the product. Wanted to know if any of yall had good experiences. I have a 2016 hMazda 6 with mild carbon buildup on my valves. I cleaned it yesterday as best I could with what I have as well as the intake manifold and throttle body but the valves are a bitch to get to. I should’ve snapped some pictures before putting it back together but what ya gonna do.

Pros use walnut blasting...

Should I do it myself and buy the equipment, or take it in? Do you know what it typically costs?

[u/robbobster → u/_slightbuzzingsound]

Unless you're using it as an asset for your business, I don't think it makes sense to buy the equipment.

I was fully prepared to have this done when we pulled the motor out of my 2018 Suburban (it has direct injection)...but after 115k miles without so much as a catch can, the intake/backside of valves was surprisingly clean.

I’m sitting about 152miles right now learning as I go. Didn’t even know this was an issue until I got bored the other day and just took off my manifold. Did the guy give you a quote on the service for your vehicle?

Last i saw for a Mazda3 or VW diesel 4cyl was in the $750-950 range but was 3-4 years ago.

Yeah fuck that dude😂 cheaper to buy my own shit and do it. Then do it for my friends for beer money 😂

[u/robbobster → u/_slightbuzzingsound]

No I had to delete cylinder deactivation hardware (common on these motors) and it all had to come apart anyways. I had quite a long list of things to check and replace, cost would have been very minimal. They didn't charge me hardly any labor to replace a ton of parts including torque converter.

sounds like you got a good deal. Was it still on warranty at the time?

[u/robbobster → u/_slightbuzzingsound]

Nope. $4k labor plus parts. It's a common issue for GM and Dodgee V8s

Jesus

If this was an effective method, the pros would be using it. Are they?

[u/_slightbuzzingsound → u/Max_Downforce]

I have no idea tbh, I stay out of shops if I can manage something on my own. Have deadass kept this car running off yall and YouTube😂

[u/Max_Downforce → u/_slightbuzzingsound]

They walnut blast the intake.

[u/bchooker → u/_slightbuzzingsound]

Actually, they do. BG Products is a professional brand of chemicals and tools that require their certification of training for a shop to be able to use. Find a shop that has BG services and they’ll do a full fuel & intake cleaning service without media blasting, so they’re not removing any parts. It’s surprisingly good for the cost. It’s a $200-300 service at the one dealership near me that’s actually BG certified.
