Common Issues With The Ford Powerstroke 7.3L Block and Heads (and how we fix them)

  • Valve Issues- The 7.3L was plagued with inferior valve and seat material from the factory.
  • The original design used parent material for the seats. And the seats were known to wear at higher rates causing the valve to sink further into the head.
  • The valves of the 7.3 are commonly known to wear down well below the margins.
  • Leaving razor sharp edges that can fail leaving the piston to take on the remainder of the valve in the cylinder.
  • We only use brand new valves that exceed OEM standards, which do not have this issue.
  • Excess Sand From Casting Process – Excess Sand from the manufacturing process while uncommon, can clog the oil cooler, but more commonly would beat upon the water pump
  • causing premature failure. By use of our extensive cleaning methods thru media blasting,
  • furnaces, spray cabinets, hot tanks, and ultra sonic equipment, we have protected your investment.
  • Powdered Metal Rods- For the most part, 2001-2003 7.3L’s came with Powdered Metal Rods that were prone to failure around the 400 HP mark.
  • These rods are only an issue at higher HP levels which is why we use forged rods for anything above 400 HP.

Optional Parts are not installed. Optional parts are covered under the manufacturer’s warranty and not by CHOATE.
