Went up to camp this past week, I guess it got pretty cold cause the freeze plug on my Ford 850 had popped out, the one near the battery. I put it back in and put some antifreeze in it. When I started it there was water coming from the exhaust manifold, the front middle port (2port). Is there a gasket between the exhaust manifold and the engine block that may have gotten bent or moved? I checked the oil and it wasn't milky. I haven't pulled the manifold off yet was thinking I would cause more problems if the bolts broke off. Any ideas? I can start and run the tractor it just leaks a bit. Thanks
