Thanks for all the clarification on the Injector and glow plug access.
Pictures are really deceiving! But it's great to know that there is good access, sure some extra time...but I'd rather have the extra power and spend more time servicing the truck!
As for the Hypermax system, if you look at the picture under Dave's engine in post #1 you'll see the Hypermax turbo is sitting right in the center of the engine, leaving good room on each side for servicing. But as we just went through, pictures can be very deceiving!
