I've got a 1990 L10e cummins, serial #34640147. I am trying to find the overhead setting procedure for this engine. This engine is too old for cummins quickserve to have the manual online. Called Cummins tech support and they told me they don't have access to that information but gave me the number to a dealership that should. Called the dealership and they proceeded to give me the valve lash which I already had since it was on the data plate on the side of the valve cover. They then told me they didn't have the actual procedures and directed me to another shop who told me they were not allowed to give out specs. I know the firing order is 1,5,3,6,2,4 and I have top stop injectors. I really just need to know in what position do I set which valves and in what position do I set which injectors, and how are the injectors set (pretty sure they are supposed to be set at 6 in-lbs but not positive). Thank you
