Oil pressure

[dVolkart]

Ford 4cyl 4000 oil pressure drops to 0 when going up or down steep inclines, takes a little while to return to normal?

is the engine full of oil we must know first. and how steep? is it returning to normal once tractor is level? give us some info.

I suspect your pickup tube is
cracked or broken. Pull the pan and
look before you destroy the engine.

Had a Ford 640 that did that. Added a
1/2 to 3/4 quart of oil, over full,
that solved it.

Was not quite up to the full mark, but close. Was cutting wood in the woods so some inclines were fairly steep.
