Carbon Question

[Wagoneer622]

Hopefully you guys can give me some ideas as to take care of this problem before I rip the carb. and intake manifold off my truck. I have a carbon problem, It is built up in the intake, I know this for a fact and it really starting to get me mad becuase the truck is running like a piece of crap. I have been dealing with this for a while I just haven't had the time to do the work with school and everything. My vehicles always run and when they don't it embarrases me, it has gotten to the point where it is causing an annoying pop through the exaust. Just wondering if any of you guys had any ideas before I rip the intake off and that will lead to the heads coming off to get cleaned. Thanks in advance.

where is the carbon building up?....there was a thread on this a while back, you can pour water down the carb with the truck running and it will burn out the carbon......if you do this pour in a tablespoon at a time.....you may try and search for the thread..

Thanks, I was going to try that I just wanted to make sure my father wasn't the only one that knew that method, god only knows with him, now I will def. try the water down the carb. I just wanted to hear somebody else say that.
Anybody know of a carbon cleaner that is sold in auto parts stores fpr the combustion chamber and the intake? Just in case this doesn't work well. I know what cylinders where the build up is, I didn't want to pull the intake until I got the new one. Thanks again!!

I think the water trick is the best, but you can also try a product called Dura MAX. They sell it in most auto parts stores as a kit that goes into your oil and fuel system. Pricey at $35. It supposedly helps oil sink into the metal for better lubrication at startup and a by product is that it releases any carbon buildup that might have stuck to valves and other surfaces. I used it in my 86 BMW and it seemed to work. I was cautioned however to be on the lookout for oil pressure buildup or new oil leaks. Apparently when the carbon releases it sometimes plugs up oil passages. I think this would be true using the water method as well.

I also use an Amsoil product called Power Foam. it is by far the BEST intake cleaning product I have ever used!!!!......and it makes somes of the nastiest smelling, incredibly thick white smoke!!!....

the benefit to this stuff is it is a foam, so if you spray enough in it fills up everything and cleans everything!

Success Story: Chevron Techron

I'm a skeptic when it comes to liquid cures but this one gets two thumbs why up.

I had a carbon build up issue in my combustion chambers due to a PO not fixing the rich mixture of the carb. With only one treatment of this $6 fluid my carbon issue is gone. I had considered the water down the carb method, but that seem way too risky. For other success stories just search for information on Google groups regarding Chevron Techron.
By the way you can get the stuff just about at any parts store or Wal-Mart.

After the treatment, you will need to have your timing and/or carb mixture setting adjusted to prevent the carbon from building back up if yours was caused by a rich mixture / incorrect timing.

Glad to see someone addressing the cause as well as the cure. Carbon means rich and/or retarded. Read your plugs. Any number of reasons for rich. If your timing does not hold, you've got a sprocket/chain problem. Common on old motors.

Hey Guy's,
I want to thank you for the suggestions!! smile.gif It seems like the water did the trick because the truck is running a lot smoother than it was before. I just have to put some octane booster in and check the timing,then I should be good to go.

Thanks Again,

Nobody mentioned PB Blaster. Carbon removal is the intented use for it although everyone I know uses it to loosen rusted bolts. I used it after I rebuilt my carb wih very good results. I had to pull the intake soon after to replace the cam and there was very litle carbon left inside. I must admit, the water method is cheaper.
