Not what I said gents.
The vasoline is a good idea, but then again the alpine is easy to field
prime the oil filter base prior to first start.
What I said was....
The oil pump protrudes through the top of the crankcase up to the
distributor mounting flange, where the pump itself is driven off the cam.
The 1"" or so of the pumps outer diameter on the top side of the pumpt
mounting
flange is intalled directly inside the main oil galley.
Quite simply, the pumps existance in that position, keeps the galley from
loosing massive amounts of oil "about all of it".
it is the close fit on a lathe machined portion of the pump, to a machined
bore in the block that intersects the oil galley.
The pump will then have two seperate locations in which they can leak
galley main oil back to the sump.
It has been found that sealing these possible leakage paths results
in higher idle oil pressures.
Since cruising OP is seldom a problem, this is a real blessing.
