When I say time I mean like over the winter. I have heard of people using diesel fuel, automatic transmisson fluid and kerosene to put in the engine instead of oil and in the spark plug holes. Is one of these better than the other or is there something better?
Thanks in advance!

I use BG's In-Force as a penetrant but it's commercial grade stuff so finding it may be difficult. Go to dealerships and independent shops, they may sell you some,

Oh, Chevman, I see you're from my neck-of-the-woods. If you ever come to Cedar Rapids, I'll give you a can. | | |

I have the plugs out and I've got clear plastic tubes stuck in each spark plug hole. I plan on soaking it until it comes loose also. | | |

It's a reasonable penetrant, has pretty good lubricating qualities, and you can buy it just about anywhere in 1 gal cans. Pour some in each cylinder and let it sit for a while... | | |

One thing more you might want to check is the valve train. Most of the time you will find stuck valves. When the motor is free remove the valve cover make sure all of the valves move freely or you could suffer push rod damage. Also you should check the fuel system such as rust and bad gas in the tank old leaky fuel pumps and rotten rubber hoses. | | |

Thanks to all! | | |

Good Luck | | |

I worked on 41 Caddy motor a few years back. I put Marble Mistery Oil in it and it worked. It will take at least four weeks but the longer the better.
Once I had it some what moving...I put the Caddy on first gear then pulled it with my other truck...It really worked then. Good luck. | | |

Squirt them with a good penatrent use a wooden dowl and a mallet to knock the piston tops with and soak it again. Continue this action till free.
I didn't do it, no one saw me do it, you can't prove anything! "Bart Simpson"

It is the best penetrant I have ever used. A friend of mine has been using it for years at his motorcycle shop and his personal restoration projects. You squirt it into the cylinders and leave it sit a few days. The company also sells plenty other excellent products. It has put all other stuff on the market to shame. | | |
