Install O-rings on a Cummins Cylinder Head » DW-1111-ORING-lead

DW-1111-ORING-lead

The combustion pressure inside your diesel engine is on a mission … to escape. The OE builds a good enough “jail” to keep it confined at stock power levels, but when you let those gasses get “pumped up” by power-adders, the stock jail may not be enough to hold them. One of the first mods the UNOH Diesel Club put on its list was to stud and O-ring the head of their 24-valve Cummins (with the help of Preble County Diesel, Fel-Pro and ARP). The engine now has the beef to handle some upgrades without another teardown, and the Diesel Club has some useful boost limits to build around.
