Anyone out there know why coolant would be coming out of breather pipe on crankcase. Is it becuase the gasket is bad? Thank's any help is appreciated.

Water pump seals bad,filling counter balancer cavity and purging through vent tube. REPAIR IMMEDIATELY or major damage to counter balancer and bearings can happen! Good luck

Must take apart to replace w/p seals and bearing. Several posts on this repair procedure. Only 75 cc's of 30 wt oil lube counter balancer cavity. On the old 350 there is not a dipstick/fill under carb,but a 14 mm bolt protruding at front of case to remove and add oil,plus a 10 mm drain plug under engine to drain fluid. REPAIR water pump first!! Good luck
