How does a Detroit 671 work?
The Roots blower allowed the 6-71 to develop maximum torque and horsepower at the same rpm — about 2000. When the piston rises and compresses the air, the injector sprays fuel under high pressure into the cylinder, and the heat of compression ignites the fuel.
Is a Detroit 671 a good engine?
The 6-71 is probably one of the most reliable Detroit Diesels, sort of a staple engine that has been around forever.
Is it OK to rev a diesel engine?
You should therefore allow your engine to rev to the redline at least once every few hundred miles – but only when the oil is warm and you’re on a quiet road. Diesel cars may also have problems with clogged diesel particulate filters (DPFs), which are designed to trap harmful exhaust emissions.
What makes a 671 Detroit Diesel engine so good?

What is the first digit of a 671 engine?
The first digit is the number of cylinders, so this example would be a 671 engine. In some older engines, the full engine size and series could be seen in the first three digits. For example, 671-RA63, the first three digits indicate it is a 6 cylinder member of the 71 series.
What should the viscosity be on a 671 engine?
Viscosity: 10W-30 and 5W-20 should not be used in the 671 engine. The recommended viscosity is SAE 30. However, if the temperature is below freezing, other viscosities may be used. For example, from 0-30 degrees Fahrenheit, SAE20W can be used. For temperatures below zero degrees Fahrenheit, SAE10W30 can be used.
