Fresh 360 Valve Train Noise.....

It could leak and drain down past the rings after each stop. Or a mechanical fuel pump can get a pin hole in a diaphragm and pump lots of fuel into the oil. Hope this catches it soon enough to avoid other damage. Bearings, rings and cylinders, cam and lifters.....

Once you examine the oil for shavings/particles, if it is clean, then put in new oil with the higher zinc levels and see what it does. (Or use the same oil and add 1/2 can of Rislone Oil Treatement or other additive to get the ZDDP levels up.)
