Oil pan..

That baked on coating, the colour is indicating age heat and oil type. If you had pulled the sump at say 3 months after engine build you would of seen a light brown fine film that cleans off quite quickly in the parts bath. Add five years many ours of hot hard running and you get what you found. It will be back.

Sump Fitment

Place sealant at the front and rear joint points (rear main bearing cap to sump gasket edge & front cover plate joint LH & RH).

When fitting up cork gaskets use a light film of aviation forma-gasket then tension up the bolts to manufacturers spec 4.3 to 7.2 ftlbs ( caution be aware that some gaskets are not made to spec and may split and push out under pressure) ideally the correct scenario same all around with a thin film of forma-gasket visible at the outer edge of the gasket the residual forma-gasket in the gasket holes,on the bolt threads locks them for you and prevents roll back.

To the other positive crank case ventilation system (gas recirculation) issue quick check, if you back off your oil filler cap, engine running uninitiated shut down should occur if the engine is correctly sealed up. Other check, disconnect hose at PCV valve, plug the hose, start engine, a hiss should be heard from the valve if it is working properly. The air flow is in from the hose to the manifold thru the Valve.
