the oil has coated the top of the piston and the cylinder walls, new engine oil is very thick, not like depleted oil like in the engine and it has sealed the leaking area. give it a few drive cycles and it will go back down. best to take it easy on it until the problem is fixed. without the cylinder combusting with correct cylinder pressure can be harmful.
