PROBLEM
This letter only applies to 3600/C280 Gas and Diesel Engines that have Reman cylinder heads installed. This failure may occur within 3000 hours. Certain Reman 3600/C280 cylinder heads were built with Reman intake valves that have incorrect surface finish on the valve tip. This can cause excessive wear on the valve bridge. If the existing valve bridge wears excessively it can/will lead to dropped valves.
