I'm looking to find out the feasibility of doing a valve job on a B2G truck without taking out the engine. I have heard that it can be done fairly easily, but it looks to me like it would be hard to reach the valves even after the side covers on the engine block are removed. It looks like I would have to remove the passenger side fender and then the manifold to have any chance of getting in there. Removal of the head will not be a problem. Has anyone done this already? Any tips or suggestion
