Remind me not to buy any used "running" engines from you guys (IMG:style_emoticons/default/laugh.gif)
Engines don't just seize. This engine was stored outdoors, and water clearly got into it. Without even knowing exactly what the cylinders look like, I can guarantee that there will at a minimum be significant pitting in the bottoms of the cylinders where it was stuck. I've seen unacceptable pitting on the bottoms of cylinders that weren't even seized but just had condensation in them from Mid-west humidity. Ring breakage is a very real risk in the process of getting it unstuck. Which ever valve(s) let the water in, well, that valve and valve seat won't be so pretty either. Finally, I shudder to think about all that rust being scrapped off the cylinder walls and ending up in the oil. I've seen cranks and oil pumps scored from pumping rust. It's real, it isn't pretty, and it will be unavoidable in this situation. As was stated previously, I have no doubt it probably can be unstuck with the methods proposed. It can probably even made to run. Will it ever be a good, reliable, engine? Not in my book. |

The only way to be sure you get an engine that will run a long time is to pull it and rebuild it. |
