oil found on top of intake manifold valley

[PaulRV6]

I noticed oil dripping from underneath and could not find the source until I happen to look at the intake. Noticed oil on top of valley, so I am suspecting it is leaking down from there. Any ideas where this oil might be coming from? Did have this oil leak before I pulled the engine to clean it from brg damage. Thanks

I also have just recently found oil on top of my intake valley under the coil pak. It appears that the intake is leaking.I also have a good size leak coming from the oil pan in front of engine. Bad rubber felpro gasket.

It's probably leaking from your PCV. But you might also be leaking from the gap between the intake and the back of the block (end seals) which is what you'd see leaking down the side.
