Hi all,
I just waded through some 2900 posts hoping to find this had been
answered,but no luck.
I have replaced both valve cover gaskets and that helped.However,there
is still a leak topside that I can't find.Someone had told me that
when GM ditched the distributor,there is still a hole in the intake
manifold that now has a plug in it that has an o-ring that needs to be
replaced.
Has anyone heard of this or had to do this?What needs to be removed to
do it?
Thanks!

I had exactly this problem with '88 Chev Celebrity 2.8. The plug and
hole are at the top rear of block {driver's side of crosswise engine).
As I recall it was under something that had to be moved out of the way
for good access. I had it done at a shop at the time I was not sure
where oil was coming from.

The plug with the O-ring is located where the distributor was in older
models. The plug is part of the shaft that the camshaft uses to drive
the oil pump. Removing the air box and air rubber piping up to the
throttle body should give you access. Once a new O-ring is installed
the shaft may have to be rotated slightly to slip into the oil pump.
