You're correct. Bob Smith of American Diesel says a properly cared for Lehman will last around 15,000 hrs. Mine is a 1986 and has around 5000 hours with no problems. It'll outlive me for sure. If you're buying one, an oil analysis will tell you if there are any problems, as long as the oil has some engine time on it. If it's just been changed, the owner may be trying to hide a problem.
