We'll my car recently had its head off and everything went on correctly, but when I started it it wasn't idling on its own so I pulled a spark plug wire off and found that all 4 spark plugs were filled with oil to the point where I wasn't able to see the plugs anymore.
Any suggestions?

 

Bad valve cover spark plug o rings. I'd just get a new oem gasket valve cover kit.

 

easy fix, happens often

change your v/c and tube seals
