: I did just this recently on my freshly
: built 2.5.
:
: My temporary shaft was a good bit
: smaller than the pump shaft. The
: effect of this was that I did get scary
: amount of oil coming out around the
: shaft, I think partly because only a
: relatively short section of the pump
: shaft sits in the bush and partly
: because the oil feed hole in that bush
: sits above the top of the pump shaft
: and the smaller temporary shaft was
: doing nothing to restrict the flow as
: would normally be the case.
:
: In spite of this I did get oil pressure
: (as measured at the standard location
: for the pressure switch) pretty rapidly
: although only 20 - 30psi. I didn't
: hold out for oil coming through to the
: rockers - the feed is metered via flats
: on the rear journal of the cam so you
: wouldn't necessarily get anything much
: coming through with the cam stationary.
:
: I then fitted the pump drive gear etc
: and spun the engine briefly on the
: starter which gave me 50 psi more or
: less immediately.
:
: Engine has now done 150 miles or so and
: gets 35psi at 700 rpm idle even when
: properly hot and 60 psi @ 2000 rpm - so
: I'm happy with that.
:
: Good luck!
