Blue Ox Posted January 13, 2019 Share Posted January 13, 2019 I have a 2000 ch613 with e7 460. The jake was dropping out so pulled the valve covers to check it out. I found the exhaust valves had 1/4 inch lash. Adjusted them to .025 and tried to start it. The engine wouldn't fire. Backed the adjustment for the valves back closer to what they were before and it starts but sounds like the jake is on. I have had the truck for about 3 years and had not touched the engine before and don't have any past history on it. Any ideas on what the problem is?
