05 6.0 PowerStroke HP Oil Leak at Injectors:
Some vehicles may exhibit a hard or no start with low ICP pressure readings. Remove the valve covers and inspect for oil leakage where the oil rail installs onto the injectors. If leakage is found the affected injector should be replaced. Inspect for a missing oil inlet o-ring or spring clip. If these parts are missing, they will need to be located or engine dmage will result. Look inside the rocker carrier on top of the heads, in the oil pan and on the oil pick up screen. If the missing parts are not in these locations, remove the lube oil pump and regulator and inspect. Broacast Message 3862, 4582.
