Guest Ray Newport Posted March 18, 2003 Share Posted March 18, 2003 Fired up the 49 Roady this past weekend. Notice condensation in the exhaust when starting up. Not very much, was gone after a few minutes. Check engine found no water leaks. What possible problem i could be having, and how can i head it off. Thanks in advance. Ray Newport BCA # 30054.

jerryacheson Posted March 18, 2003 Share Posted March 18, 2003 I think condensation in the exhaust at startup is pretty normal. I wouldn't worry about it. The key is to get the exhaust up to operating temperature often to burn any water out of there. Otherwise, you'll have an early retirement for your exhaust system. Good luck.

NTX5467 Posted March 19, 2003 Share Posted March 19, 2003 Great comments, Jerry!Just like when the warm front meets the cold front, moisture happens, just like condensation on the outside of a glass of a cold drink. It is normal and will be worse in colder ambient temperatures.In the '60s and '70s, Chrysler OEM mufflers had a small hole in the rear on the bottom to let it drain out, plus a similar hole in the tail pipe near the back. Not big enough to cause an exhaust leak sound, just enough to let the condensate drip out. Of course, once everything got up to operating temp, the drips stopped. I don't recommend adding holes as those were OEM spec for those cars.As Jerry mentioned, not letting things get all the way up to operating temp can affect service life of the exhaust components. Just because the engine is at operating temp doesn't mean the exhaust system is as it takes longer to get warmed up and the hot exhaust gasses to cook out the condensate just as the warm engine will let similar condensate in the crankcase evaporate as the engine stays at operating temp for a good while.Just some thoughts . . .NTX5467 Link to comment Share on other sites More sharing options...
Guest COMPACTBC Posted March 19, 2003 Share Posted March 19, 2003 Hi Ray, You got some good answers re the condensation out of the exhaust pipe,it's no big deal as long as it goes away when things get warmed up. I sent you an email awhile back re our lodging info for our caravan back to Flint on 7/18. Did you get it? Are you still planning to make the trip with us? I havn't heard from you in a long time. <img src="http://www.aaca.org/ubbthreads/images/graemlins/tongue.gif" alt="" /> Link to comment Share on other sites More sharing options...
Smartin Posted March 19, 2003 Share Posted March 19, 2003 Bruce, your avatar looks familiar...like the hood emblem of a 71 Lesabre convertible <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" /> Link to comment Share on other sites More sharing options...
Guest Posted March 19, 2003 Share Posted March 19, 2003 Simple chemistryWhen you burn gasoline (hydrocarbons) is produces two things (if complete combustion) - carbon dioxide and WATER!. When the pipes are cold, the water condenses. That's the clouds you see in the winter.HC + O2 ---> CO2 and H20 Link to comment Share on other sites More sharing options...
Guest COMPACTBC Posted March 20, 2003 Share Posted March 20, 2003 I'm not sure but I think it is a '69 or '70 center of the grille emblem. <img src="http://www.aaca.org/ubbthreads/images/graemlins/tongue.gif" alt="" /> Link to comment Share on other sites More sharing options...
