[Roadsters] Third Posting

 Stupid question of the day:
Could you drop the oil pan and shoot some oil up into the innards? would be a bit of a pain but there could be a bunch of gunk in the pan you don't want circulating anyway.

1969 SRL311-12936

Happy Saturday,

Bear with me as the first part of this note perhaps doesn't look like it
belongs here.......

My wife and I do a lot of home canning, and after processing the last batch of
tomatoes, I attempted to remove the bands from the jars so I could wash them
before storing.  The bands were stuck.  The solution was to hold the jar under
running water.  This got some "lubrication" between the metal band and the
glass jar, and also dissolved away some of the tomato juice which may have
come out of the jar during processing.

And you ask, "How does this apply to Datsun Roadsters?"

In my First Posting to the group, I said I was beginning to restore my 1969
roadster.   The machinist who will be working on the motor requires that I
first get the crank turning (indicating the pistons are not "seized" in the
cylinders).  I put a socket on the vibration damper nut and attempted to turn,
but it wouldn't.  I've shot lots of lubricant into the spark plug holes,
without apparent effect.  With the scenario of the canning jars above, what is
the chance that the problem is not stuck pistons, but rather, dry bearings
(crank, rods, cam, jackshaft, etc), and if I could get some lubricant to them
I might get the motor innards to move?

If the issue is really dry bearings (it's been sitting without running since
about 1974), how might I externally pump oil into the motor?  Some years ago I
watched another motor being restored.  The machinist gravity fed oil into the
oil pressure sender port to be sure there was lubrication on the bearings
before attempting to start the newly rebuilt motor.  Does anyone have insight
into how I might attempt this with the U20 motor?

Looking for lots of responses.......
