A perfect running car produces power by changing fuel into water and CO2. The engine is warm enough that the water is normally vapor. Cold engines on a cold day may spit some water. Condensation in the muffler also causes this issue to an extent.
is there any formation of aquaregia inside a vehicle muffler..? any answers..!! I assume you mean from the tail pipe. Water is a bi-product of combustion & is expelled with the exhaust. -LubeExpert
If there is a rotted hole in the muffler please replace the muffler. However, if there is a small hole at the bottom end of the muffler it is there to allow water to escape.
No, Do not drill a hole in your muffler! The water evaporate when the car gets warmed up. If you drill a hole in your muffler, The next time it gets inspected it will fail.
a gas line over the muffler may have broke, or you car is older then 20 year old
Your bad muffler might be part of the reason your check engine light comes on. Usually, your bad muffler causes something else to go wrong and that causes your check engine light to come on. Problems cascade.
Global warming.
Is it a 2 stroke motor? If it is that's normal
Start the engine. Most of the water will be blown out and what is left will evaporate from the heat.
I think what you are seeing is your muffler leaking condensation from a weep hole. This normal and will stop after your vehicle has reached full operating temperature.
