Re: mercruiser 200/v8 hose out of valvecover?????
They shoud go into the side of the flame arrestor. The elbows that look like PCV's are hollow, the idea is for the engine to draw the crankcase ventings in. Excessive oil vapor blow-by is what you are seeing, and , well, you should not be seeing it even if your engine is worn and has a lot of blow-by, it should vent into the carb's airflow.
