Better check to see if any oil and coolant are mixing. Could be the intake manifold or timing cover seal. Maybe one or both of the water outlet bolts pass through the housing and into the intake or block in an area exposed to oil and corrosion on the bolt shaft allows it to escape. I'm shooting in the dark, not as familiar with the Cleveland.

If you're running traditional ethylene glycol coolant it has an oily consistency and, mixed with dust and dirt, could appear this way.

Have you checked under the valve covers to see if there's foam?... PCV?... Oil breather? Anything in the radiator? Is it overheating? White foam in any of the afore-mentioned areas would indicate you have oil and coolant mixing. Easiest would be the intake gaskets. Worst case is a blown head gasket.

No oil in radiator and the oil does not seem to be mixing with the coolant .... Intake gasket leaking down ??

I run 50/50 anti freeze chuck could thàt be ?? Or the intake is leaking up in front ??
Now, for legal purposes I have to say "don't try this at home"... I have taken a "sample" of such leaking fluids and touched the tip of my tongue to said "sample". Antifreeze has a distinct sickly-sweet taste. Oil does not.

As far as an intake leak... oil, possible but not common. Coolant, no. No coolant flows into the intake on a Cleveland.

Why does everyone run a flex hose from the upper radiator to a Cleveland? :shrug:My car had the same flex hose when I got it.

Anyway, I would suggest cleaning the area with some carb cleaner or brake clean and a small brush. Then see if you can find anything leaking.
