Each piston is regulated by the crankshaft it is mounted on, and both crankshafts are set upon one common crankcase. The 5.4 triton motor was developed by Ford Motor. It was first manufactured in 1997 for the Ford F-150 truck.

What Can You Use the 5.4 Triton Motor in?

The 5.4 triton motor is for use in full-size trucks and large sports and utility vehicles. It is typically used to power the Ford F-150, the Lincoln Navigator, the Ford Expedition, and other similar vehicles.

How to Know if Your 5.4 Triton Motor Needs to be Rebuilt

There are a few tell-tale signs that mean that your motor needs to be rebuilt. The most common, and important, ones to watch out for are:

• You hear knocking or rattling sounds when your car is idling 
  • Signals an issue with a timing chain or bearings
• There are loud clattering sounds as you accelerate, which are disruptive enough to be heard over the radio 
  • Signals an issue with the pistons, piston belt, or timing chain
• You notice engine oil in the coolant or coolant in the engine oil
  • Signals an issue with a cylinder, head gasket, or engine block
• The motor does not turn over consistently 
  • Signals an issue with a starter or in the wiring 
• There is blue, white, or thick smoke coming out of your exhaust pipe consistently 
  • Signals an issue with a head gasket or engine block 

Each of these issues signals that there is something different wrong with your 5.4 triton motor, and therefore will require the rebuilding of different parts, likely costing you different amounts of money. 

How Much Will it Cost to Rebuild?

The average cost of rebuilding a 5.4 triton motor is $3,800, though it can range from as low as $1,800 to as high as $5,000. If this seems like a lot, remember that replacing the entire motor can cost you between $6,000 and $7,000, so rebuilding it is usually worth it. 

The parts that need to be rebuilt will determine how much it will cost you to rebuild the motor. If you rebuild the motor yourself, then you will only have to worry about paying for the parts.

If you have your motor rebuilt professionally, you will also have to factor in the cost of labor. However, rebuilding a motor is very complicated, and you should only attempt to do so if you have experience working with cars and engines.

If you plan to rebuild the motor yourself, you can plan to pay around $2,000 to $2,500. If you plan to have it professionally rebuilt, you should expect to pay around $3,500 to $4,000.

However, the parts that need rebuilding will significantly determine the cost.
