Water dripping from an exhaust pipe immediately after starting the car is a perfectly normal reaction caused by the combustion in the engine. If water still drips from the tailpipe after the engine has been running for a few minutes, it may be the sign of a serious problem.Know More
When a car is started, combustion takes place inside the engine. During this combustion, water and carbon dioxide combine forming condensation that is often seen dripping from a tailpipe, especially on cold days. In a well-running engine, as the engine heats up, the condensation stops. This usually only happens in the morning, but can occur anytime after the car has been parked for several hours and the engine has had a chance to cool off. On warm days, or in a warmed up engine, the water released by the engine's combustion is still there in the form of invisible water vapor.
Water dripping from the tailpipe long after the engine has been running may be the sign of a more serious condition, especially when there is smoke or the smell of burning oil present. If the car has a sweet smell, like the smell of antifreeze, this is a particularly worrisome condition. Any of these signs suggest a much larger problem and the engine should be looked at by a qualified mechanic.Learn more about Car Parts & Maintenance
There are a number of ways to make a vehicle's exhaust system sound louder, including adding exhaust tips, replacing the muffler with an aftermarket brand designed to amplify the sound and replacing the rubber mounts on the exhaust pipe with welded metal hangers. If done correctly, these modifications will make the exhaust system sound louder, but will not compromise its ability to safely exhaust engine gases.Full Answer >
Blue or gray smoke coming from an exhaust pipe indicates either an oil leak or piston wear. Typically, oil leaks pass the seals and get into the engine cylinder. From there, they come into contact with gasoline and burns, producing blue smoke. When oil leaks into the cylinder, it produces rough idle, misfires and could affect the spark plugs, according to CarsDirect.Full Answer >
Straight water should not go into an engine at all, but people can use a mixture of automotive engine coolant and water which can be poured into the car's radiator using the radiator fill cap.Full Answer >
The oxygen sensor is positioned inside in the exhaust pipe, and it is used to detect rich or lean mixtures. This sensor is an essential component in the emissions control system, and it transmits data to the engine's computer. The primary function of the oxygen sensor is to help the engine operate as smoothly as possible by detecting the appropriate air-to-fuel ratio and using fuel efficiently.Full Answer >
