The 2 aluminum ones are for the drain plug for 2 after job oil changes.
The large blackie is for the oil filler neck or some such.
The 2 thick blackies (and the 2 "unsiamesed ones") are for an oil cooler or some kind of thermostat housing.
The 8 singles....one for each cylinder??
The 4 Siamesed ones gotta be something you missed under the valve cover.
