Ok so I have a few things going on and the main one is that I might have one or more rod bearings going out. I have a really loud clacking sound like right when I start it which quiets down after about two to three seconds. The clicking sound comes back when I'm letting off the throttle or staying at a very steady speed. I'm losing oil and coolant and so I might have a blown head gasket too. I'm really hoping to hear other things it could bbe that are cheaper and easier than replacing the whole damn bottom half of the engine. Anybody have an idea?
