Got my 705 lpg out for th first time I had worked the engine over. The middle head gasket failed at about an hour and a half plowing. I need to get the wrench to get on the stud nuts around the water manifold. Anyhow I replaced the gasket and set the valve of course but it still has a miss. Also the water manifold now leaks around the front head. I was in a hurry I problably made a big mistake by not removing the stat housing to get to the front stud on under it. I used a mallet with boxed end wrench. Could I have lost another gasket??? I am thinking I will have to take it apart and I am going to come up with the offset adaper to get on those manifold nuts. What else could be the issue??
