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

•  The 7.3L was plagued with inferior valve and seat material from the factory. The original design used parent material for the seats. Consequently, they were known to crack from heat cycles.
• The valves of the 7.3 are commonly known to wear down well below the margins. With razor sharp edges which 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.
• By use of our extensive cleaning methods thru media blasting, furnaces, spray cabinets, hot tanks, and ultra sonic equipment, we have protected your investment.
• 2001-2003 year model 7.3L's came with Powdered Metal Rods. They 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 the Workhorse Model engines.

Optional Parts are not installed or covered by CHOATE. They are subject to the manufacturer's warranty.
