Hi:
I would like to start a discussion on engine pre-oilers. Examples of these would be the Accusump unit. As I understand these devices, they are used to pre-lubricate the upper valve train and pre-build
oil pressure charge befor the engine is started.
Benefits are supposed to be that the valve train and hydraulic lifters are not "dry" prior to engine turn over. Less wear. Possible safety net if engine
oil pump dies.
So that is about all I know about them....
It appears that a somewhat large reservoir is plumbed into the
oil line via an oil adapter.
To those of you who are running one of these pre-oilers, I would much enjoy your input, installation suggestions and overall assessment of the unit from a functional and dependability perspective.
I have a 428FE, hydraulic lifters, with functional external oil cooler and 8 Qt Milodon Circle Track Oil Pan. External oil cooler is fed from the oil filter housing via braded AN lines.
