How do you or can you remove the carbon build up on a 1995 gmc jimmy I removed the erg valve and it was full of carbon how can you do more from other areas that has built up?

Technically, what you have is sludge buildup. Most oils deposit sludge on engine surfaces. Sludge is a waxy substance that precipitates out of heated oil. Unfortunately, there is little that can be done to completely clean out sludge from the inside of an engine except for a complete engine rebuild. The good news is, the sludge won't cause too much trouble all by itself unless a large mass is dislodged and plugs up the oil pickup screen in the bottom of the oil pan. I run fully synthetic oil in my vehicle because synthetic oil has far less sludge production. Unfortunately, you should not change to synthetic oil if your vehicle has more than 50,000 miles on it. You can use some engine cleaner additives to the oil that will partially disolve some of the sludge, but if you decide to do that make certain that you change the oil at short intervals to get out everything that disolves.

All of the answer above has nothing to do with the question. Oil sludge is a bottom side of the engine problem. The person asking the question already informed us it is carbon buildup in the exhaust. I don't know of a easy way to correct this except to remove exhaust system from the headers back and clean with carb cleaner. Then use a fuel additive to clean the injectors and cylinders.


I had a 97 Jimmy with a similar 4.3 Vortec under the hood that you might have 8/10 chances for that year. If you just bought the vehicle and discovered this, you might have had a previous owner that drove the vehicle with low acceleration which caused the high amount of blowby in the PCV and the carbon deposits slowly and coolly being left along your exhaust system. One way is to get a fresh oil change (thicker is better in summer), and drive the vehicle hard. I'm not saying to break the law as that is not something one should do. I'm just saying you can accelerate in such a way that you can maximize some hot air pressure going through the system for a week or so. This usually does get rid of built up carbon in the air exhaust system.

Both the respiratory and urinary systems remove waste and harmful toxins from the body. When we respire, or breathe, Carbon Dioxide is removed as this is not healthy for the body.

To stop carbon build-up on cooking pans, soaking the pans in warm water and soap and then scrubbing with an abrasive cleaning tool will help remove the build-up. If the carbon resists, then it's recommended to buy a pumice stone to scrape the stain off, but this is advised for only stainless steel pans.

First you have to remove the cover after cover is removed turn the build holder counter clockwise

You first need to remove the side cover at the top of the cylinder on the right side. Once this is removed you will expose the power valves and power valve actuator rod. You will need to remove a cotter pin that holds the actuator rod to the power valve shaft. You can then remove the power valve shaft. The power valves will come out through the exhaust port. It is best to have the cylinder head removed and expansion chamber removed for access. If the shaft wont pull out it is because of carbon build up. You will need to spray the shaft and valves with solvent. The shaft should pull out.

Yes, the oceans remove carbon dioxide from the atmosphere. Because there are high levels of this greenhouse gas the oceans are becoming more acidic. This is damaging corals and preventing shellfish build strong shells.

Carbon dioxideThat is as carbon source. Carbon from CO2 is used to build up glucose

it was a common problem with the J30 engines, the repair procedure is simple, they remove the intake manifold and simply use a drill too remove the carbon build up and give it a good cleaning they also install a small tube to help it from building up carbon as fast.

yesIt is the source of carbon. They are used to build glucose molecules

Can be a few things. You can be using too low an octane fuel. But that is highly unlikely unless you have a high compression engine installed. Can also be the engine is not timed correctly. Check the timing. More than likely the problem is carbon build up in this 31 year old engine. You have carbon build up on the pistons which is causing pre detonation. There are products on the market that will help remove carbon from your engine. Seafoam is one of them and it works quite well. You can also remove the heads and manually remove the carbon. You can try that or you can switch to a higher octane fuel. This pinging is harmful to your engine over the long haul so do whatever is necessary to remedy this.

the molecules that build up your body are: carbon dioxide, oxygen, nitrogen, and hydrogen

Brushing and flossing can remove plaque which causes calculus to form. But once calculus does form, it is too hard and firmly attached to be removed with a toothbrush. dental visits are necessary so that calculus build up can be professionally removed with sharp instruments. Source: i am a dentist
