T444E need some care
These engines are a very good engine but do require some occasional new parts. The first item to need replaced are the small return hoses and usually the plastic caps. Some times the fuel filter will become restrictive. Most folks replace the filters, oil, add some Power Service and advance the fuel setting. The milage will dictate when most of the repair is needed. My 1990 Blue Bird has the same engine and an Allison. Aside from low power, I love this bus. Frank
