I have a 2001 fe400 that had a camshaft bearing break and spit the balls throughout the engine. I found all of the bearings, replaced the broken bearing, broken balancer drive gear and put a new timing chain on while I had the engine apart. I lined up the dots on the new gear and placed the cam lobes down, but I can't get it started. No feedback that it is even about to start, I have a spark. Could my valves be that far off? or am I missing something with the timing?
