When you're getting oil on a plug... (all my plugs get oil with my 75 SBC 350).. but 2 usually get it the worst. I would put those plug extensions on them to avoid this but... the headers don't allow that where I have the problem.
If I remember, oil on a plug is a simple problem meaning a gasket or a seal or something in the valve covers.. what is it again?
if you get oil smoke on start up its oil leaking onto pistons (valve seals and guides) .thats a tell tail sign that its up top. if smoking and fowling plugs on warmed up running and compressions ok you have oil ring problems , If your plugs are oily and smell of petrol as well you have spark problems.. thats my thoughts,
