I have a 97 ranger that is puking water on the back side of the engine almost as fast as I put it in when hot. On the way home from work it sounded like I had a desiel engine. Hoping one of the freeze plugs in the back are bad!!!!! Its been losing water for a while but not very much.. Could not it be the block? If so my engine is a 3.0L I have a 2.9L. Would the existing tranny work?
