Spark Plug Change in a Truck--How Hard Can it Be? Update#2

Well I know the Ford 6.7 liter diesel doesn't use spark plugs, but today a tow truck operator, flipped the hood so I could take a gander at his F 450's engine.

Geez...is it ever tight in there. I'm glad I'm not a modern tech. I don't think the gassers have much more room under the hood.

I mentioned to the driver that I recall the 1960's when a guy could almost fit in either side in the engine bay, with a Chevy small block V8 in the middle.

Those days are gone.
