Re: motor problems
Did you put on Marine head gaskets? If you are boating in salt or brackish water, standard automotive gaskets will go away very quickly.<br />You could also have an intake manifold gasket leak.<br />Also check the gaskets between the risers and manifolds. If the surfaces where the gasket touches isn't shiny metal (Flat black and soft, is not netal) they need to be replaced. Water in the cylinders can leak past the rings and get into the oil, especially on a new or rebuilt engine where the rings are not seated completely.
