lets see... have you worked for mitsubishi for 17 years?
well, i have. they dont wear out. its not the "evaporative recirculation" system. its the crankcase ventilation system.
yes, they CAN get gummed up... but that's only if the car is neglected in the first place. change and maintain your oil, and its shouldn't be an issue.
