Thank you for the replies!!

Evil Spirit..That was very interesting so I checked into the sonic cleaning. I haven't as of yet found anyone who has a tank large enough for a engine block. Although it looks great for cleaning small parts every nook and cranny from grease , rust etc..

Rebel....Thank you for the update on the antifreeze information. I am going to try it and see. It may take the combination of antifreeze, heat and circulation. I have a few ideas.

Lock jaw...I am not 100% sure on the magnetic question. I was able to scrape some of the filler off and it didn't seem to have a magnetic quality. But, it was a small amount and I really wasn't looking that specifically. I will re-examine that soon. I can say that this was done many years ago. Late 80's possibly.

Again, Thank you for these excellent ideas and information. This is why I keep coming back to MoParts.

If you don't start it , you don't have to end it.
