Stuck F

[birddog019]

Well I'm working on my 40 that the PO had sitting for about 10 years. I'm trying to determine if the F engine is seized or not. The PO said it ran before he parked it. I took the radiator out today and got a socket for the "big ol nut" and can not move/turnover the crank. I don't want to try to start it because I don't want to damage anything if it is seized. I took out the plugs and put a little oil in to see if that will loosen anything up. Does anyone have any advice or tricks on how to determine if I'm in for a rebuild? Should I get a pipe for my 1/2" drive to get more leverage? Any help would be great.

Thanks,
Brian

A freind of mine just through some oil in like you along with some diesel and let is sit for about a week, then he broke it loose with a breaker bar.

The oil in the cyliders was going to be my first suggestion. Also I have heard of people fitting an airline into the spark plug hole and using compressed air to turn over a engine. Need to make sure you are above TDC.

Never tried it though...

I did this once... first get a 3/4 drive . A real man tool Put good penetrating
oil in the combustion chamber (no WD-40 please ) Everyday, add oil and try to move it... It took me 2 weeks to make it move. good luck

I did the same with a 2 F that sat for 3 years. Pull all the plugs and get the wifes turkey baister. I used marvel Mystery oil as suggested and shot some in all of the cylinders. I am told and verified on my engine that you should be able to move the harmonic balancer by hand. But I would try the longer breaker bar.

I have done this on a tractor as well. All plugs removed, Light oil in the cylinders let it sit. Try to turn. If it won't turn, let it sit a few more days or as I had to, pull the pan and loosen the main bearing caps then retorque to spec.

Starter is not that strong. If damage will occur with it then the motor is already in bad shape.

Sqirt some Marvel/wd40/Kroil/PBBlaster in each cylinder and goto town...
