It's coming out the back side of the head 5 and valve cover 85
Expert:  Curtis B. replied 7 months ago.
8 is the engine vent. Is vent hose open and connected? It can leak oil and it will run down the head.
Customer: replied 7 months ago.
That's all good
Expert:  Curtis B. replied 7 months ago.
it is not the valve cover leaking? If not the vent, it has to be valve cover or the head gasket.

Could it be the crank seal under the flywheel
Expert:  Curtis B. replied 7 months ago.
It would have to go uphill to come off the cylinder head
Customer: replied 7 months ago.
I have the cover off around the head but I don't see any oil now and it's full off oil
Expert:  Curtis B. replied 7 months ago.
