The 7.3 engine has some issues with its cylinder pressure which can result in engine failure. This might lead you to rebuild your 7.3 engine. In total, it will cost around 9500$ to 10000$ to rebuild your 7.3 engine. The parts will cost around 8000$ to 9000$ and the labor cost will be around 1000$ to 1500$.

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

Configuration Of A7.3 Power Stroke Diesel Engine:

The 7.3 power stroke engine was Ford’s first launch of the turbo charger diesel V8 engine. The engine is from the Navistar T444E family. The engine was introduced by the company in the year of 1994. The company produced the engine till 2003.

The parts used in the engine were exclusive and original as it was the first power stroke engine.

A list of the parts used in the 7.3 power stroke engine:

  1. 444 cu in the 16-valve ofV8 (7.3 L)
  2. Waste Gated Single Turbocharger
  3. 104.4 mm bore and 106.2 mm stroke
  4. Compression Ratio 17.5:1
  5. Dry Weight (417kg)
  6. The engine produces around186 Kilo Watts and 505 lb which is equal to 250 horsepower of torque. This power is produced in the automatic transmission trucks
  7. The engine produces around205 Kilo Watts and 525 lb which is equal to 275 horsepower of torque. This power is produced for manual transmission trucks
  8. 15 US Quart (14 Litre 12 Imperial Quart) Oil Pan.
  9. Top end high-pressure oil pump which holds an extra03 US Quart2.8 Litre and a 2.5 Imperial Quart.
  10. In total the engine holds 18 US Quart and 17 Litre 15 Imperial Quart of oil.
