I do not think that just because myself and a couple of others have made several posts across two different forums about my issues that it means these engines have a longevity problem. There are lots of different problems that cars and trucks have all the time that never get reported to the interwebs.

Also remember, the Explorer uses an aluminum block, where the vast majority of these modular engines are cast iron.

The maintenance crews of major fleets for taxicab companies and government police agencies will tell you over and over again, that the modular engine is one of the best designs they have ever seen.
