Hi all. I'm trying to figure out where my oil leak is coming from. The highest puddle I can find is below the valve cover, right next to the timing cover. I've replaced the valve gasket when I had oil in the spark plug and replaced the o rings under the rocker arm. Any help would be appreciated. I've attached pictures but may not be any help.

 

It's a 93 4cylinder

 

there are no pictures visible.
it'd probably help to say the model of car and which engine, instead of just "93 4cyl"
