I copy and pasted this from another post I made,

here is your quote:
"so I decided to crank it and CAUTIOUSLY watch it, oil immediately starts blowing every where instantly shut it down"

you made a reply stating this,
so.. you DID run it.... that means there is gas in the top end and galleys ...journals and all...

What does this mean and what should I do about this, I haven't ran it yet, I was going to crank it and run it for a while Sunday, but after reading what you said I think I'll wait to here what you say, I DO NOT want to ruin this tractor because a mistake this. My dad bought this tractor in '79 and afterwards I started taking care of the repairs etc.. and my dad was killed in Dec. '89 and my Mom gave me the tractor and different things happened and it set for a number of years, I've finally gotten it running and then something like this happens and now I afraid. I was thinking about cleaning the inside of engine because it set so long but not like this.

You said............
checked the oil and it was WAY over full
I decided to crank it and CAUTIOUSLY watch it
oil immediately starts blowing every where
I drained over 3 gal. of oil and gas out of the oil pan

So now we know you DID start and run the motor if even for only a few seconds.

Gas will not lube parts. In fact it washes the lube (oil) off the parts. With no lube you are running the motor dry metal scraping on dry metal.
When you cranked the motor the oil pump started working as it should and drove the gas oil mixture threw out the entire motor.

Now that you are about to beat your head on a wall thinking you just ruin a good motor I will add............
Stop worrying. You only ran it for a few seconds. At most you took a month off the life of the motor.

On the other hand learn from this. If ever you find something wrong (oil way over full) ask first before you try running the motor. If you had run it for a while; say 30 min to a hour; you would be buying a new motor for your tractor right now.

You now have a nice, clean engine. By now, most of the gas in the engine has probably evaporated, leaving nothing to lube the bearings on initial startup. You have two choices: either cross your fingers and start it up, or try to pre-lube it. If it was my tractor, I'd just fire it up. The few seconds without lubrication aren't going to be significant compared to the 60 years of use your tractor has seen.

If you want to go the pre-lube route, I think you can remove the distributor, then make a shaft with an end shaped like the end of the distributor shaft. Then insert your homemade shaft through the distributor hole into the oil pump and spin the oil pump using an electric drill. Once you have oil pressure, the engine is lubed. I've done this with other engines, but not with a Ford 172; I assume it will work.

A compromise between pre-lubing and "fire her up" is to pull the coil wire and crank the engine with the starter until you have oil pressure.
