244/236? You sure its not 236/244? I doubt you have reversion with it dry that far out. Something is leaking inside the engine.

Head gasket, intake gasket, cracked block....etc...

My cam is a 230/244 112 LSA (small block chevy) with over an hour of idle time in the driveway, no reversion, oil is crystal clear, with stock manifolds, spacers, and risers. I am beginning to think a lot of the cam reversion issues I read about that had me scared to pick "too big a cam" are due to other issues.

Are you seeing a full milkshake with water in the oil filter or just a little sludge under the valve cover?

Thats pretty normal and doesn’t indicate anything major and often caused by the water being very cold in particular if you’re running a crossover or not getting the oil hot enough. Engine blocks sweat just like a cold beer bottle on a hot day so the oil has to get hot enough to burn it off. I had the same issue on a mild 502 when I upsized the oil cooler. I put a thermostat on the oil cooler and solved the issue.

What is the cam LSA? I always put a small bead of rtv on both sides of the water jackets on the intake gaskets just for a little extra precaution.
