Drill did not labor; I forgot about that point. Significance of this action?
Curious about packing oil pump with grease. How does this help? Not being a dick, but want to add to knowledge base.
If the drill is not "laboring" it is because the pump is not building pressure which requires more torque/effort from the drill.
Packing the pump with grease fills the clearances inside the pump so it is more prone to pull (suck) the oil up in the pan.
I agree on the fact that it has already primed so this is more than 98% likely to have you chasing your tail.
The relief valve is a possibility and easily removed with out even pulling the pump.
I also agree with pulling the valve covers to verify all the lifters are still in place.
