Oil for a Slant Six that's been sitting a long time

Needsaresto, your advice about a priming tool applies to V8 engines, but this is a slant-six engine. The design of the oil pump drive is such that there's no such thing as a priming tool; the oil pump cannot be spun independently of the engine. The oil pump can be primed by removing the cover plate and packing the cavities with vaseline, but without doing that priming is limited to pouring oil down the central hole where the oil filter mounts. A couple tablespoons of oil can also be shot into each cylinder and the engine can be cranked with the plugs removed to lube the cylinder walls.

As the slant-6 in question turns over, there is no extreme potential for damage by cranking or running it. The main thing is to make sure it's full of clean oil thin enough to get to the bearings quickly.
