Oil leak passenger side

[steelynorm]

So i noticed a small puddle of oil under the engine on the passenger side only.
I opened the hood to discover a thin film of oil on passenger side components.

I Have not had a chance to further investigate, i just noticed it.

Any ideas.... i have 220k on her.

Check the valve covers.
