I find that Caterpillars are cleaner and tighter than most diesels. Mine have 1400 hours on them and they don't leak or drop anything........I don't even use diapers. With out the AirSpes, the crankcase vent tube will drop few drops of oil and you will have a slight mist. With them, you can eat lunch in the engine room.
