1. What causes low turbo boost pressure in the 14L Engine?
These are the causes of low turbo boost pressure in the Detroit 14L Engine: wastegate problems, air leaks, and a failing turbo.
2. What are the signs of a failing turbo in the Detroit 14L?
When you see these signs, you should know you have a failing turbo;

The answer is yes. But the answer depends on the level of your knowledge in mechanics. You should be able to understand the wire connection and the rotation of the starter, either right or left. Then you should also know the voltage of the starter.
If you could understand this basic knowledge, then you should be able to install the starter yourself.
5. Can I drive with a leak on the water pump on a 14L?

d. Wrong oil type
e. Damage the oil relief valve
8. How to test if the oil pump on your Detroit 14L works fine?
To test the oil pump, you need to use a mechanical oil pressure gauge. This will help you to ascertain the condition of the oil pump.
9. What are the signs of a bad liner in the Detroit 14L Engine?
A bad cylinder liner causes the engine to emit blue smoke, low compression, piston slap, blow-by smoke, and coolant in the oil in case of a crack.
10. Can I replace only one cylinder liner, or should I replace all?
It is recommended that you replace all the cylinders rather than replacing only one cylinder. Replacing all helps the engine to remain balanced and helps you to know when to replace the liner again.
