I recently started a rebuild on a seized 1.8. I found that moisture has seized the rings and the exhaust valve on #2 cylinder. The piston is seized near the top of the exhaust stroke.
Any suggestions to free up the piston rings? I have heated the top of the piston, used penetrating oil, tapped with a mallet, etc. So far, no joy. |

Penetrating oil. Lots of it.
2x4 against the piston. And hit it with a big f*&king hammer. No, no. Harder then that. HARDER! It will break free. |
