oil on spark plugs?
The last few times I have changed my plugs, I've noticed there is some oil on each one. My first thought was to replace the valve cover gasket and the 4 o-rings. I did this but it did not help...
What could be causing this, and is it a serious problem?

yea, if you ask me its the rings check it out it might be messing with your compression also. The rings are worn-out making it easy for the oil to seep in through the combustion chamber. Good luck bro.

do a compression test AND a leakdown test, that should help figure out weather its your rings or a burned valve! but either way, getting oil on your plugs means a rebuild, be it a head rebuild/valve job, or bottom end/whole engine rebuild!

Just wanted to clarify...
The oil is not on the bottom of the plug where the actual spark is. I figure if it was, the plug would not even spark at all or maybe I wouldn't be able to tell because the oil would just burn away.??? It is in the middle mostly right where the threading is and it's not completely saturated, but there is a noticeable amount on there.
I don't know if this makes any difference or not but just wanted to describe it more clearly.
Approximately how much will it cost to get a compression and leakdown test done?

if its noticebly only on one side of the sparkplug and there is basically none on the other side, then you very likely have a bad valve guide/valve guide seal......which means taking the head of and getting a valve job, because doing just one valve is kinda pointless as the others could follow suite.....

seem kind of weird cause you said you changed the v cover gasket and all o-rings. if it is a ring problem the oil is riding up on the walls of the combustion chamber a wetting the plug from the threads down. i hope i explained this correctly either way what ever the problem is you should get it checked out ASAP .
