Grinnall (Rover) 3.5 V8 oil pump issues??

Recommended Posts

Hi there, for those of you who follow my Grinnall reports, you'll know I have had some issues with the engine in my Body style 2 Grinnall, it started with the dizzy cog stripping which I suspected was caused by a repro dizzy, however now I suspect the oil flow to the top of the engine, have a look at the video, whilst the flow seems OK, the continual spitting of air looks strange to me, your thoughts are welcomed. ;) FYI I did loosen the rocket bar to see the flow.

Physics tells you the air has to be getting in on the inlet side of the pump. Where you go from there I'm far from sure.

Good luck.

Pump intake pipe split or dropped off?

Not much remains:

Gasket between block and front plate or

gasket between block and pickup tube

or pickup tube broken.

My bet is on the flange of the pickup tube,

very easy to bend.

 

Why not swap to the crank driven oil pump?

There is an intermediate cover to have that and distributor on board.

This is a crank driven oil pump at the bottom and the old clockwise rotating water pump at the top.
