Yes after all the breather is puffing out air over hot oil in the crankcase. Problems only really arise when you have had an overheating siezure and the rings get gummed into the grooves. In this case apart from poor compression you will see the oil cloud rising up behind the primary chaincase at tickover and a large deposit on the floor when you finally park up! :headbang:
