Reason for having separate logbooks is to allow parting out of your plane's main components (airframe, engine, propeller) and keeping all pertinent documentation with it. As an example, this can easily happen if you upgrade from a fixed pitch propeller to a constant speed. The fixed pitch propeller log would be provided to the end-user when you sell that propeller.

Ask yourself this question: If you were to sell or replace your engine, would you include that item (that you mentioned) with the engine? If so, then include it in your engine log.

Rule of Thumb

Normally it would go in the airframe book. However, if you are in doubt, there's no reason you can't put it in both.

anybody using the EAA green logbook? really easy to use but no place to sign off work done.

If the part or appliance was not installed on the engine when engine was new it is an airframe item. Examples are starter, alternator, vacuum pump, engine baffling, exhaust, prop gov.
