hi guys,

i would just like to verify from the diesel experts/users here if the practice of 'flushing' the exhaust pipe with water helps or damages any part of the engine. ive heard people go through this routine of putting water in the exhaust pipe till its fills up and then they start the engine. all the water and the soot comes out, thus making the pipe cleaner. they say water doesnt go up to the engine itself, most of it is in the muffler area.

does it bring about any benefits? or will it bring damage to the engine?

thanks.
