Are you sure is wasn't fuel? I never pulled a cylinder head on a diesel with all GOOD injectors where one or two weren't wet from fuel. IMO it's due to when the engine is shut down and some fuel is injected but not fired as the engine stops. The holes are very tiny if you look close enough. The washers always come with the drainback kits but they don't need replacing unless you have a reason to pull the injectors.
