My 440 was rebuild 10 years ago, ran a season or two, maybe 1000 km's on it, then stored for 8 years. I got it going again this season. The valve cover breather gets loaded up with blow-by oil vapour and drips on the header creating a puff of smoke. This is not new. It did this from the start. My thinking is the rings didn't seat properly. The valve covers do have baffles in them. I have a high volume oil pump on the engine which some say may contribute to excessive vapour.
Anyway, it was suggested to me to put a 90 degree elbow on the valve cover and run the vapour to the bottom of the carb via a 'tee' with the pcv hose. This way it will get burned up in the engine and not drip on the headers. I know this doesn't fix the blow-by. The engine runs good otherwise, no smoky blue. Before doing this, I need other opinions or thoughts. Thanks.
