The 7.3 power stroke V8engine is the first engine of the power stroke engine series of Ford. The engine has some issues with its cylinders. The extremely high cylinder pressure causes premature failure of the engine.
I get calls from time to time inquiring about how to avoid this trouble. The answer is- you can easily rebuild the engine with some stronger and better accessories. I am going to share my experience on this as an auto technician. Rise and shine!
Major Defaults Of A 7.3 Engine:
Ford used some good accessories in their first-ever power stroke engine. However, the company erred in manufacturing. The poor manufacturing process of the company is the main culprit behind the premature failure of the 7.3 engine.
Let’s take a look at the major problems of the engine-
1. High Cylinder Pressure:
The 7.3 engine has an issue with its cylinders. Fuel is injected into the engine at a fixed speed. The speed increases with the load. When the load increases excessively, more fuel is injected into the engine causing inner engine pressure to rise.
As a result, when the engine pressure rises at its peak, it shuts down the engine immediately. Repeated high cylinder pressure in the engine causes premature engine failure to the 7.3 engine.
2. Connecting Rod Failure:
The connecting rod failure is a very common problem in a 7.3 engine. Extremely high cylinder pressure causes the connecting rods to fail. Connecting rod failures result in catastrophic engine damage. It can severely damage the crankshaft, camshaft, and the block.
Other than these two major problems, the 7.3 engine has some other defaults as well.
7.3 engine problems:
- Cover harness in the under the valve
- Valve spring failure
- Leaks in the turbocharger
- Leaks in the fuel filter
- Pressure valve failure
- Pressure regulator failure
