Hello all! First time poster here, I have a JD 445 and I am just finishing up the plastic camshaft gear replacement with a steel one . Thanks to everyone’s input on threads on this site it’s gone pretty smooth until trying to start it. I ended up replacing the head gaskets as part of this because I dropped a valve into the cylinder when trying to replace the valve springs (oops). I have it all pretty much together now and I hooked up the battery and turned it over a few times to check for spark and that cylinders were moving, everything checked out. I buttoned it all up which included topping off the oil and coolant, then I went to start it, and nothing would turn over, it would only "click" but not turn over. I pulled out the left plug and coolant started pouring out! I pulled the right plug, and same thing full of coolant. I drained the oil and there was not any coolant in it (Still looks like new oil, not milky) and I drained the radiator (coolant looks fine). I checked all the hoses and everything appears hooked up correctly. So I added some water back into the radiator and it flows out of the right side plug almost as soon and as fast as I can pour it in the radiator, I put the plug back in the right side and the flow of coolant comes out the left side spark plug hole. The flow is fast enough that it seems its coming faster than what would come through a gasket that was seated poorly, or through a small imperfection in the head where the gasket hits. Maybe I have warped heads but didn't notice?
I'm looking for suggestions on where I go from here, is this for sure a head gasket problem and I am pulling the heads again? Am I overlooking something simple? Any suggestions you may have are appreciated.
