Pre oilers

[MalcolmV8]

I've been reading this thread with great interest. Can someone explain a little more on how the accusump works? I'm curious as to why it has a valve to operate that you need to open and close manually or electrically via a switch?

Also when the car has sat for along time how do you make it pre-oil the system? Do you charge it with your air compressor to force the oil into the motor?

I'm thinking this would also be a great addition to a daily driver which has to deal with 0 degree winter start ups. Getting some oil in there first would be a big help.

I also have an 03 Cobra that sits over the winter and pre-lubing it before summer time startup and even after oil & filter changes would be great.

Thanks for any additional info on how this works.
