After replacing the fuel injection pump, the injectors, and the turbo, we still have an engine knock which seems to be a timing issue. Our mechanic will open the front of the engine to ensure the engine and the new fuel injection pump are in sync. Weekends and holidays always seem to get in the way of solutions, that is, engine parts and mechanic's work schedule. Hopefully the work to be done will be completed by the end of next week. At least, we are approaching the time when we will be rewarded with the Key to the City of Ketchikan for patience, persistence and success.
