Most of the engines we work on will last the life of the car without needing a rebuild. We have one customer with almost 400,000 miles on her original engine. There are of course fluky failures like an Integra that burned a hole in the head behind the back side of the valve seat at 40,000 miles and an Civic that dropped a valve for no apparent reason, but problems like these are rare. So if the cause of the engine failure in not apparent to you, be sure to ask.

You may want to use a micrometer to determine the bore diameter, or, you can get a good idea of the wear to the cylinder walls by looking at the cylinder ridge. The ridge is the point where the cylinder is not worn because the rings do not rise that high in the bore. The cylinder wear should be below this point.
