When I was changing my spark plugs I noticed that there was oil in cylinder 8 and was wondering what that is from and how should I fix it? Is it a valve gasket, seal, or is it the PCV

Was the oil inside the cylinder itself as-in in the combustion chamber? or oil sitting on top of spark plug hole?

My PVC went bad and was causing the oil pressure to increase and forced oil into the top of the valve covers where the spark plugs are installed. Can also be leaking valve cover gaskets.

Do you think I should just replace the PVC and the valve cover gaskets then? I found a PVC on eBay for around $27 and it looks like an easy fix, I will also check the hoses if there is somewhat of a blockage in them too. And I think I might just replace the gaskets as a precaution. Thanks.
