Default Re: Model A motor froze-up

What comes Next! Betsey, when you do get it to turn over, remember, there is rust on the cylinder walls and the camshaft and other parts as well. This rust rubs off and gets into the oil as an abrasive particle, much like sand. And much like sand, they can destroy the engine. It is a balancing act to know how long you should take to get this contaminated oil out of the system. Too long and you risk damage, too soon and you don't get enough of the particles. The old story I heard was about ten minutes at idle speed. Then it has to be changed. When it's changed, pour a qt. of diesel/fuel oil through the engine to flush what ever particles are left behind. This will begin the desludgeing process. Put the cheapest DETERGENT oil you can find. After about five hours (of running) or so, Drain this oil out and replace with a somewhat better quality oil.
