Fun with carbon
Hi NG!
I was helping my friend with his car the other day when he produced a spray-can of liquid which allegedly, when sprayed down the intake, will clean the carbon build-up in the combustion chambers. I happened to have a couple of carbon-caked heads lying around from a 1600dp and sprayed a little of the stuff directly on one to see what would happen and the carbon literally melted away. (I feel like a commercial) Can't get ahold of my friend or remember what the stuff was. Seems like most spray-on stuff doesn't work that well. Any ideas what it might be? Thanks!!!! BM |

wait a minute..... what about the heat riser on the intake? If there is
something that "melts carbon away" then it would be an answer to prayer for cleaning the intake.

I had an old Honda Civic years ago that had a clogged EGR passage, and my BIL had this factory GM stuff that he used to clean it out. Not sure if you can get it at a local dealer or not though, and I can't remember the proper name or part number. It was pretty potent stuff, a little went a long way. |

GM's Top Engine Cleaner works well. You pour it down the carb in a small
stream with the engine running and then dump the last bit in all at once and stall the engine. You let it sit for a while and then start it back up. You should see lotsa black coming out the exhaust if you have a lot of carbon build up. I suppose you could use it on a disassembled engine. Water, which is cheaper ) works almost as good. A trickle from your garden hose down the carburetor whilst the engine is running. (you'll have to manually work the throttle to keep it running) As for something that works with the heads off of the car, regular spray type carburetor cleaner probably works fairly well. Maybe that was what was being used. Most heavy crusty carbon needs a bit of scraping no matter what. >>>Mike |
