Blown Head Gasket?

Driving out west to go snowmobiling on 4/15/09 and truck started to lose power and egt were elevated so I pulled over on the freeway and checked oil and degas bottle and both levels were fine. Started truck again and it ran fine for about 5 mile and then the motor lost all power and shut down. I was lucky enough to be able to coast up an off ramp prior to the shut down. Checked the degas bottle again and it was overflowing and definitley contained oil in the antifreeze and the oil level barely registered on the dipstick. My son and I pulled it into town of Fargo, ND where it sat Until today when a trucking firm I hired delivered it to my hometown.

Any idea as to where I start in diagnosis of the problem?

This could be the oil cooler may be leaking. The oil psi is greater then the water psi, so that is something to look at.

Sorry to hear this.

What is the procedure for checking out the oil cooler in order to check if it may have been leaking?

I have never taken mine off, so I really don't know how to do this. I know it is on the drivers side of the engine. It's the long tube on the outside of the block.

You most likely have an injector cup that has failed.

Is there a method to check the engine for injector cup failure short of removing the injectors and inspecting each one?

I would probably start with a cylinder contribution test via a scan tool and see if any faults show up. I would then do a compression test and/or a leak-down test.

You could also pull the valve covers to see if anything is obvious.
