i've taken my xterra through alot of water and mud, resulting in the engine bay being somewhat of a mess.
is this mud going to affect the engine's wellbeing in the long run? i understand an engine can hydro-lock and can obviously be killed if submerged, but how about just a little mud here and there? i don't take it too deep into puddles but just enough for the fan to shred it all over the engine bay.
and if it is damaging, what is the best way of washing everything off?
