I pulled the odd side head and found what I expected -- #3 cylinder rusted to the wall and maybe #3 valves rusted in heads. See photos.

Most of it looks pretty good if you can see past the carbon deposits. All the cylinders but #3 drained brake fluid past the rings. I'm ready to try a longer soak and see how it goes.

I've heard brake fluid, diesel oil, Marvel Mystery Oil, trans fluid and vinegar. Any other rust eating suggestions?

Thanks,

David
