So you just blow pressurized air through it huh?

Can you tell me about any other things that need attention? Like maybe that big tube that goes across the top?

Thanks a lot for your help!

Yes, the tube that goes over the top of the engine is usually referred to as the crossover tube. Take that off, clean it out with carb cleaner and a cheap brush or a rag or whatever works for you. Brake cleaner works too but can leave a film that actually attracts soot.

As for finding more stuff to do, start browsing older posts in the different forums here. You'll find a lot of things that have popped up for one or more people over the years. There's always something to do on these trucks!
