Did an oil and filter change for my Bugeye today.  One thing that has
always bothered me since I built this 1275 was how slow the oil was to go
down through the head to the pan. I have a raised valve cover for room for
the 1.5 rockers.  I can pour two quarts of oil in the filler neck and then
I have to wait for it to go down.  It fills up the entire valve cover and
takes several minutes before I can pour the 3rd quart in.  When I built the
motor I used hollow pushrods of a larger diameter than the standard type,
but I had the through holes in the head for the pushrods enlarged as
required for these pushrods.  Maybe the holes are not big enough in
diameter.  Would this be a problem in normal operation of returning the oil
to the pan while running?  I have put 3000 miles plus on this engine since
the rebuild and it is still running great, but the oil pressure reads 90
psi on start up and goes down just below 80 psi when warm at speed.  For
some reason the engine runs fine and puts out plenty of power.  It's just
every time I do an oil change the slow drain into the engine makes me
wonder.
