6.2L/6.5L Tech Tips 2017
The Diesel Page has always provided essential information that can be found nowhere else. This Tech Tips page adds to a very long-long list of essential information that we all need to get the most out of our GM diesel. As a consequence of solving a tough 6.5L diesel crankshaft problem, I've answered a few questions that no one on the Internet knew the answer to - at least none that Google could find. For example, with certainty, what is the damper bolt size and thread pitch? What is the configuration and number of the bypass valves used in the engine's lubrication system? How do you prepare a used crankshaft for service that is not 100% perfect, but is nowhere near needing a regrind or even a repolish? Again, certainty is required at times, and especially when rebuilding a 6.5L diesel. I'll answer these questions right here - with certainty.
