As the old saying goes, your never too old to learn something new. As I have gotten older, I have gotten more brittle, and I basically don't want to crawl around on top of diesel engine. I have been removing the front wheels and jacking the rear of the truck up forever now in an effort to make the engine may more accessible from the flat of my feet. My new shop is not very truck friendly an requires a floor jack and creeper to do any truck work. I had to put injectors in bank 1 so I only removed the right side 19.5 wheel and tire and lowered it down. I was able to reach everything but struggled to get the valve cover out. I finally realized that the body and engine had twisted and closed up the gap to the evap box.
I had to replace another bank 1 injector on a different truck afterwards and it dawned on me that if I dropped the driver side down only, then the opposite effect would occur in relation to the engine and evap box. There was so much room that I could get a Snap on torx socket on the lower oil rail bolts. It was nice and refreshing and I wish I knew about it a decade ago. Of course I probably wouldn't know about still if I hadn't moved to this ill equipped shop.
