hello all, i thought i would post a note to some on this forum. i had a problem of my 3/5 running rich, it would yield black soot out of the tail pipe, i checked everything on the engine with a scanner and so forth, left no stone unturned. well i also cleaned out my EGR ports as well, good idea to do, is to drill a hole in the exhaust manifold, inline with the EGR port, this way if you want to clean it out in the future, all you have to do is remove the plug, run a cable and drill into it and it will come out the other side when cleaned out, re-install said EGR valve and it's done.(install a very shallow pipe plug) what i am really posting about is when i checked my plugs they were a perfect white color, all of them, no how is it running rich out of the exhaust pipe with soot if the plugs are a pretty while color? i investigated it and found that with the EGR system not working correclty do to being clogged it will run good and proper at the correct air/fuel ratio, but the way the egnine is designed is some of the exhaust gas must be recicrculated to slow down this soot process. it also helps the burn of the combustion chambers as well. mine took a while to clean out the exhaust after fixing it, but it did fix it, must be in the fuel as well. but if you think your running rich and the plugs say otherwise, then clean out both EGR ports test the EGR system and it should be ok.it worked for me anyway. mine is now yielding pure clear water, almost like from the tap. it did slow down and finally stopped. if your yielding out soot, think of what your doing to your converter? it's ruining it slowly but surely, mine was brand new and i didnt want to sacrifice it. so if your fighting a rich problem but your milage is good and plugs look perfect, check the EGR system. it DOES make a difference. just letting you know ron |

Pure clear water? I posted awhile back about the clear water. I cleaned my ports while the intake was off and the exhaust manifold was off new vac hose egr completely cleaned transducer completely cleaned. I have pure clear water a bunch of clear water. I can take the top off transducer take filter out and squeeze the water out. I can take transducer off shake it and water comes out ALOT. I can take egr off push the plunger in and get a stream of pure clear water. I can squeeze it several times and get a stream of water. I changes motors made sure everything cleaned new exhaust manifold. Complete new exhaust system. New o2 sensor almost every sensor new. Have not changed map yet its working fine. I thought muffler might be bad even though new so I exchanged it for another new one. My mpg has went back up to 42.89, but I think it would be better if I could get the water problem fixed. So my question is where is the water coming from and how do I stop the water from coming back. When the weather drops below freezing the egr system freezes completely. Any help would be appreciated. |

well if you have antifreeze in you engine and you have clear water problems, we both know it is not leaking. your problem is from condensation build up, how to fix is a brain teaser. wonder why yours is so bad? is your PCV cleaned out? maybe you could add a drain to it somewhere so it would drain out and not get clogged up. use a dirt leg or water leg to let it drain out. or use a extra solenoid to open the drip leg every so often to let it drain. maybe hook it up to the computer somehow? ask geo glenn, or stiffchezze or dayle, or scoobs as well. they have heard of this problem id bet. trying to help ron |

I would suspect that the water comes from condensation. |

Just changed the plugs and they was white. Then after watching the video of ky I checked my timing. I didn't think a motor would run being over 12 degree out. It was past the timing marks above 20. After setting it back to 8 like he said, the idle went down the engine doesn't shake and it fixed the high low idle surge when turning on the heater fan. Haven't been able to check the gas mileage yet but will post when I do. Hopefully will fix the water in egr. |

I admit, I like brain teasers. did that dry up your water? Just curious. |

to continue this saga: mine has the soot problem still. it is putting out clear water, but that is expected, but my plugs are still white, and im getting soot specs still. maybe its the way there supposed tor un? maybe i should check the compression, all though i have excellant vaccum, but i might check it. maybe its the fuel i run? sometimes its worse than other times, maybe i should stay with either bp or shell, or sunoco, and not switch around? i think i will try staying with one brand, i do know one thing, i dont use sunoco that much, so its either bp or shell that might be a culprit? i will try it next. right now its trying to whiten up the exhaust tip and i have shell in it i think. all gas is pretty much the same, ive talked to a guy who drove a gasoline truck, he went and filled up the huge tanker you see at the stations when they fill up. he drove the truck for years, he says, its all the same, except when you go to fill up the tanker, there about 20 different nozzles and you have to pick the right one that is designated for the station your taking it to, which means they are demanding more or less of the additives to come up with there own formula, but gas is gas, except for the additives. it what he says anyway, he drove the truck for years and years. maybe its additives making the soot, by the way, my wifes monte SS has the soot and its never thrown a check engine light even once? but it has the soot ? i bet if you look at alot of cars they have the soot as well. maybe we should look around huh? i think it may be the powder carbon from the catylitic converter and after it burns the gases it puts out carbon dust and mixes with the condensation and make soot? sounds possible to me? to be continued i guess |

In perfect combustion the byproducts should be carbon dioxide and water. Clear water from the tailpipe is normal. |

If you don't have a service engine light that says you need to service your EGR system, you're wasting your time. The best automotive fuel in the USA is available in the State of California. The California Department of Natural Resources, Air Research Board (CARB) approves fuel that is sold in the State. My favorite fuel in the State of California is Chevron (or Texaco) with Techron. Chevron or Texaco with Techron is my favorite fuel. Next is Conoco and BP. If none of the above are available, I pour in a 12 ounce bottle of Chevron Techron Concentrate with the fuel and call it good. Read about Top Tier Fuels. The additives are in fuel to keep your engine clean. Ethanol is part of the blend, so get over it. http://www.toptiergas.com/index.html Also, the fuel we use in our motor vehicles is made up of several hundred molecules of carbon. That black stuff that comes out the exhaust is made of carbon. As long as the fuel used in motor vehicles is made from carbon, black stuff will come out the exhaust. http://geometroforum.com/single/?p=635320&t=4763711 Our friend mwebb might chime in and admonish you to use good engine oil.
