I started working on a fence a couple weeks ago and while I was working the tractor ran out of gas. It was getting late so I left it out for the night and intended to fill it up in the morning. Well turns out I got busy, the tractors parking spot under the barn got filled with Christmas presents that needed hiding, and I didn't get to the tractor for a week. As it was sitting out it rained....a lot. I didn't worry much about the tractor because I had installed a rain cap on the exhaust a few months ago. I went out to start the tractor, which is an IH 674 gas, and it wouldn't start. One of the tabs on the ignition switch had mysteriously broken off so I went to NAPA and "switched the switch". Now the tractor turns over fine and has spark but won't fire. So I went to pull off #1 spark plug and found a puddle of water around it. It was also sitting in there very loose. I noticed also that #3 spark plug was quite rusted were the socket sits to screw it in. When I pulled #1 i found it smelled of gas but also had little droplets of water on it. The same for #2,#3, but not #4, they had water on them but were not loose. So i decided to drain the oil. I pulled the plug out slow and about a quart or so of water came out first, and then the oil. SO....my question is by removing the oil plug will the water run down through the motor by gravity or is there something else I need to do to remove the water from the cylinder head? And do you think that much water could enter the motor from a loose plug or should I be looking for a blown head gasket or a cracked cylinder? Any help would be much appreciated.
