@Ultramaroon knows what he is talking about, look at your radiator cap or reservoir cap for small leaks, even apply a pressure tester if you cannot find the leak. In theory, metal on metal parts should never wear out as long as the proper lubrication is applied. (This means regular maintenance and services, and checking fluid levels and contamination regularly.)

Agreed.

Though, I believe the key is preventing contamination in the first place.

Meh. Overrated.
