Thank you to all of you who helped me find the manual and parts list for my Case 446 Onan engine, it's really appreciated a lot! Guess what! I have another question. Here it goes....what would cause the engine to blow gaskets. We put new gaskets on where they should have been replaced when it was rebuilt, but it has blown one again under the breather area....I know some of you know the story about the terrible rebuild, and the motor blowing oil, but that story will have to be written another day! Right now I'm just full of questions.
