Hey, today I discovered some oil around my spark plug on cylinder #6 on my 84 K5 Could I get some possible causes/consequences and maybe fixes. As of now she burns a little oil in the morning that may or may not be related. Thanks!

 

Where was the oil? Inside the cylinder or outside?

If inside, you likely have bad valve seals.

If outside, then you likely have a leaking valve cover gasket.
