It's me, stressing out in Los Angeles, and hoping the list can help.
I got an engine rebuild in January on my '89 GL.  Now here's the deal:

My dipstick keeps popping out.  Then, the other day after coming home off
the the freeway I had an oil spray all over my rear hatch when I got home.
**Yet the dipstick was intact.**  There was an oil leak over night beneath
the filler tube, however

So, a spring was placed on the dipstick to keep it in and it seemed to solve
the problem, although I haven't been able to drive on the freeway due to a
running rich problem which will be taken care of on Friday, so I can't tell
if my solution is really working.

Still curious, I searched the archives and read a few possiblities as to why
my dipstick pops out.  Such as: compression in crank case, blocked breather
tube, etc.

The reason I'm writing: I read a post which I copied  below.

Putting a spring on the dip stick *apparently* solved the problem, similar
to the solution above.  Or did it?  Are the above referenced problems
possible? As I've said I just had an engine rebuild and am worried to death
it could be worse than my work around solution.

How do I go about determining the real cause for my dip stick popping out
and the oil spray?  I can not seem to find a mechanic in Los Angeles who can
help solve my current problems instead of creating new ones.  Please help me
understand what's going on.
