Added (1). I own a 98 Ford Escort with 89k miles. Runs great. Will the 2.0L 4 experience the dropped valve seat problem at some point, or is it possible that it may never happen? There must be some people who never had a problem.

Others say it only happens if you overheat the engine. I'm assuming that means not flushing the radiator and replacing the coolant at regular maintenance intervals.

FORD means FIX OR REPAIR DAILY. You have an average Ford vehicle.
