Identifying Engine Codes

It's not uncommon to discover that the engine in your Bus was replaced along the way and is not the "correct" one for your year. Knowing this can save you the inconvenience of ording the wrong part! Below are some of the most common engine codes found on Busses and Vanagons in the U.S., in roughly chronological order. On the Type 4 ('72-83) engine, the code can be found stamped  just in front of the breather tower. Do not go by  the code on the fan shroud, as it may not be original to that engine.
