Hello folks. I drive a ’91 245 with 250K. Lately I noticed excessive moisture that comes out of the exhaust pipe. When I park it for a while on the dry pavement, for instance, even after the motor is well warmed up, there would be a wet spot on the ground where the pipe “spits out” (…literary) the water (or like substance). Coolant level is fine and it never over heats. It recently had a exhaust sys replaced with a new rear muffler and no front resonator…worn out Cat. What could cause this? Is this normal?.....couldn’t possibly be….HELP! Thanks in advance!
