Re: checking engine before you buy a bus
I just checked the oil; it was not even a 1/2 gallon low. oil was black and clear of metal filings. Drove the bus and checked the idling oil pressure while warm after driving it 20 miles or so. a few leaks but not really to bad. Something to be expected on an old school bus. It ain't new ya` know.
I didn't worry to much about maintenance most of these buses come from school districts that take care of the buses pretty well. Mine has a boat load of miles on it(278,000); but not enough to deter me because it is a diesel. With good oil pressure at an idle, warm; barring something unusual it should go a good many miles yet.
Transmission fluid was clean clean clean; with NO burnt smell at all.
