As far as I know, you need to pull off the valve cover to replace the cam 
seal.  If I remember correctly, one of the half moon seals is integrated 
with the valve cover gasket, while the other is a separate rubber piece.

I've done it in the past, and it's fairly straightforward, only complication 
I ran into was the bolts that hold on the valve cover gasket are very soft, 
and even with the use of a torque wrench set to spec, I still twisted 
several to their demise (wrench calibration?).  If you do it, may also want 
to augment the seal at the half moons with gasket sealer goop (technical 

I also found out recently that the intake manifold does not need to be 
removed to accomplish this job.

I'm in the midst of an exhaust manifold swap and decided that while I was in
there I'd see what was causing a small oil leak that leaves one or two drops 
oil on the ground at shutdown and over the last year or so has really gunked 
the lower part of the motor.  Anyway it looks like the cam seal is one of 
culprits (in addition to a plug in the oil galley).

My question:  To replace the cam seal can I leave the valve cover in place?

Also - I'd like to go ahead and clean up as much of the oil and dirt as 
while the EM is off and there is better access - any suggestions for a good
method?  Or should I wait til it's all back together, then run over to a 
wand car wash, spray some degreaser/engine cleaner in there and then use the
