Did you replace the 4 donut gaskets when you replaced the valve cover gasket?

they can be a real bitch to do correctly. the slightest little mistake and they will leak

did you give them a light coat of oil before you reinstalled the cam cover?
some people will disagree with this but i see it the same as an oil filter. a real light coat of oil over the seal/gasket does the trick

i did indeed apply a light coat of oil, is it possible the valve cover itself is bad

I don't oil static seals. The only reason you put oil on a filter is you have to spin it on so you need some type of lubrication when you twist that seal on tight.

there are four seals under the rocker assembly
you could put a thousand new donut gaskets and valve cover gaskets and it would never fix the issue
heres a pretty good rebuild link on d-series it shows the gaskets im talking about underneath the rocker assembly

ive never had a seal leak after putting oil on it.

I always welcome new ways to do things. Only downfall I can see in it is if you worked for a shop and did that for a customer car some might weep a little giving off the appearance of a leak.
