The 7.3L Powerstroke is considered by many to be indestructible! Even as bulletproof as 7.3L can be, lack of proper maintenance and stupid mistakes can be the undoing of this of this endurance diesel engine platform.
If you own a 7.3L or you are considering the purchase of a used 7.3L you will find this video very useful. This video will help you identify the tell-tale signs of a 7.3L Powerstroke motor in distress and what the probable causes of the failure(s) are.
In this video I start by troubleshooting and discussing evident problems with the engine. Then we tear the motor down for an inspection taking time to point out the defective components. Once we get a game plan together I show the engine buildup and finally the rebuilt motor installed in the truck. ~Bill Hewitt
