This ought to be pretty easy, but I'd like to have some instructions if
anyone can provide them.  It seems that I have to unbolt the metal
shrouding in order to get enough room to work there.  Then, I suppose I
need some kind of lever to push the valve cover latch down.  Will the
cover just come right off then?  Will a lot of oil spill out?  To what
degree should I "clean" the surfaces before putting the new gasket in and
closing it back up?  I've been told not to use any sealant, but I'd like
to make sure that I have all the important details before taking it apart.
By the way, this is an '87.

Any advice on doing this job would be greatly appreciated.

Thanks,
David
