Valve cleaners

[Doublebase]

Before you spend your hard earned money on valve cleaners/carbon removers, consider what I tried today.

 

I sprayed an entire can of CRC directly on the valve. Then I let the valve soak in CRC intake and engine cleaner for four hours (agitating the valve back and forth every half hour). Then I took the valve out, heated it with a propane torch and let the heat sink in. Then I placed the valve back in the solution for another hour. I finally took that valve out for one more direct spray. 
 

Very little carbon came off that valve. Direct spraying of two cans of CRC. A four hour soak. Heating of the valve face. Almost nothing was removed. Don’t waste your time...walnut blast these things if you want results.

Even worse than having no cleaning effect it actually looks like the solution has bent the valve [emoji1787]

It's all that damn carbon buildup!

 

I sometimes wonder...is carbon capable of hiding under my bed and biting my toes? It's why I jump 15 feet off the bed in the morning...never can be too safe:)

I’ll continue with my routine valve cleanings every oil change. Your little experiment proves nothing. The key is to do these cleanings from the get go, not 50, 75 or 100k miles in. This stuff isn’t going to magically clean valves that are already coked up. Everybody knows that. It’s meant to be a preventative measure. 
 

thanks for the good laugh. I needed it. I had a crappy day at work.

You're welcome, keep wasting your money...I hear it helps with crappy days at work. Cheers.

you should be concerned about the money you wasted on this pointless experiment lol!!!

It wasn't that much, it was on sale in the "snake oil" section, its right next to the "we have a good deal on some swamp land in Florida" aisle. Haha.

I do the same. CRC before every oil change and I run a catch can.

My valves are clean.

Can’t wait to see those pictures of your “clean valves”.

Stop talking shit bro. You thought you were proving a point and it backfired on you. Let it go and move on.

This is from their ad online, you might want to check your facts.

Yeah, not at all like how it is actually being utilized in the engine. When used properly the speed of the air along with the chemical properties of the solution are designed to erode away the build up. 2-3k rpm air is moving very quickly over the valve. I am sure it helps, better than nothing though honestly these engines probably don't really even need it, though I will do it once a year or so just for safe measure. Either way it was a formidable attempt but missing some key elements on what actually cleans the valves...

 

Warm up engine, spray valves at 2k rpm, rev engine, let soak then send it on the highway italian style; boom, done.

H2O works and costs alot less.

Yes, you have some good points. I considered the air moving past the valves and the up and down movement of the valves (which I didn't do). I figured I made up for that by spraying two entire cans on the valves and letting it sit in a solution for four hours. I also heated up the valve with a torch, before putting it back in the solution for another hour. Then finished it off with another direct blast of spray. But engine operation is different - honestly I thought by spraying two entire cans directly on the valve, more than made up for the loss of air turbulence (but I'm not sure). And I definitely got the valve plenty hot...I was a bit worried about flash igniting the solution. And I understand this valve was pretty coked with carbon to begin with.

I'd like to learn how to do that on my oil changes. My truck only has 2000 miles. I installed a Range AFM disabler and a catch can the week I bought the truck. Any good videos that show how to properly do the cleaning? I don't want to screw anything up.
