Blown head gasket is due to not enough bolt torque holding it down. Timing is critical, but I doubt you ran the truck hard enough to hurt it in 26 miles. If it was fully loaded with water and gear, and you were heading to fire at full throttle, then maybe. Next time, drive it with the dog house off if possible to hear what the engine sounds like. To me it looks like you need better head bolts or a stud kit with a better gasket. I have never had problems using Fel-Pro blue or black gaskets. 9.1 with premium fuel shouldn't be a problem. | | |
