My 1984 Euro M6 occasionaly blows massive smoke out the exhaust under hard acceleration. This has been going on for several years and doesn't seem to effect overall performance. I've heard this can be caused by a plugged, small drain hole in the plenum. Anyone have a similar experience and/or know how to fix it?
