Guest Posted October 8, 2000 Share Posted October 8, 2000 You could try disel fuel. Just pour some into the cyl and let it stand for a few days.<BR>then tap the top of the pistion with a wood block and a malet. Careful not to break the pistion. This should free the stuck rings which is probally why the pistion won't move.<p>[This message has been edited by 29CHEVY (edited 10-08-2000).] Link to comment Share on other sites More sharing options...
Clincher Posted October 9, 2000 Share Posted October 9, 2000 On more than one occasion, when all else has failed, KROIL has worked wonders for me.

Guest Posted October 10, 2000 Share Posted October 10, 2000 I used a mixture of oil and kerosene once to release a gripped piston. It worked very well in my 1951 Plymouth.<P>Good Luck.<BR>Julio Link to comment Share on other sites More sharing options...
