When evaluating a used 7.3L Powerstroke, prioritize these areas:
: A frequent cause of sudden stalling or no-start conditions; many owners keep a spare in the glove box.
: Often referred to as "OBS" (Old Body Style), these featured lower power ratings (starting at 215 hp / 425 lb-ft).
: In northern climates, the oil pan is prone to rusting through. Replacing it is labor-intensive as it often requires pulling the engine. 7.3 FORD POWERSTROKE Buyers Guide
