Hi, guys. I have an '87 Raider into which I successfully dropped a brand new 4D56T engine. When I brought it to the local diesel shop to see if the engine was performing up to specs, they told me they didn't have the tools to work on this engine, with which they're not familiar. My question: what tool(s) do I need to do this job? What should the diesel shop be able to tell me about this engine? Many thanks!
