Remove Carbon Build-Up

It’s been a long, hot, year. This would be a good time to think about removing all that carbon build-up in your engine. It’s an easy procedure that can result in marked engine performance improvement!

Carbon is a natural by product of the combustion engine. Over time it will build up, layer upon layer, in your combustion system including the air intake and the exhaust system!

The build-up restricts air coming into the system and the ability for the exhaust to exit the system. Engine “pinging” can be attributed to this carbon build-up.

The following procedure is really simple to perform. You will need two items:

  • 1 Can of the product called SeaFoam. Auto parts stores carry it and I’ve seen it at a large grocery store as well!
  • 1 – 2ft length of hose that will fit on the brake booster nozzle.
  • 1 assistant to man the controls while your under the hood.


  1. Open the hood of your car and locate the brake booster. There is a vacuum hose attached to it, remove the vacuum hose.
  2. Take your 2ft length of hose and connect one end of it to where the vacuum hose was connected.
  3. Connect the other end of the 2 ft length of hose to the can of SeaFoam.
  4. Bend or clamp the hose closed (Vice grips or pliers would work).
  5. Have your assistant start the engine.
  6. Have the assistant rev the engine up to 2.000 rpm.
  7. When your assistant has it up to 2,000 rpm, then, you, slowly, open the hose that you have closed with vice grips or pliers.
  8. Instruct your assistant to not let the engine die by revving the engine further if necessary.
  9. The vacuum of the brake booster will draw the SeaFoam out of the can into the engine.
  10. When the can is empty shut the engine off.
  11. Take a beer break, or coffee break, let the vehicle to sit for about 30 minutes.
  12. After 30 minutes start the engine.
  13. Rev the engine up to 2,000 rpm’s again. Watch the black smoke (cooked carbon build-up) pour out of the exhaust! Keep the engine revved up 2,000 rpm’s until the black smoke clears.

You’re done!! Too easy! Now your engine is good to go for another 100,000 miles or more!
