Blown Head Gasket? Here's What You're Doing Wrong
About this episode
The episode discusses the causes of blown head gaskets in diesel engines and offers solutions for prevention and repair.
Blown head gaskets are one of the most common headaches diesel guys run into once they start chasing real power, and this episode breaks down exactly why they happen and how to actually fix it for good. Todd, Will, and Myer get into it after a viral clip of a 6.7 Cummins shooting fire straight out the front of cylinder number one, and use it as the jumping off point for a full breakdown of head gasket failure. The guys tackle the biggest myth in the diesel world first, that high drive pressure is what blows head gaskets. It is not. High cylinder pressure from advanced timing is the real culprit, and they explain why a tighter turbo setup that makes drive pressure is just a sign of an engine that is going to make power down low, which is where the real cylinder pressure spike happens. From there the conversation moves into sealing solutions, starting with fire ring gaskets and split firing, which the guys call the ultimate ceiling technique for a high performance diesel build. They compare that to Top Fuel dragster hoops and C ring style seals, and explain why a fire ring is still the go to for iron block Cummins applications running big power, whether it is a 12 valve, a 24…
