Ford Contour 98 - 2.0 L - 84000 miles - worth repairs?

Hello Vero.

P0442 Evaporative Emission Control System Leak Detected (small leak)

About the Timing chain.
The water pump its drive it by the timing belt and I recommend you to replace it at the same time (new water pump never rebuilt).

Also check for prices and good service technicians to do the job, 84 K M its not that bad, you can get more miles out of your car with a good schedule tune-up and oil change.

Any car with a schedule maintenance service its good (some better than others) but even the new-ones and expensives have problems with all those sensors that reduce the contamination and increase the efficiency of the engine.

Good Luck!
