Hey--do you guys think I did any permanent damage by running it with a stuck thermostat? I only went about two miles, but it was making noises like and old boiler, and I know at least part of the block must have been dry and mighty hot and subject to some wild pressure surges when some coolant would flow in and instantly vaporize.
How would I know if I had a permanent damage?? I did check for water in the oil (none--phew) and water vapor in the exhaust ( none). My paranoia tells me it's running a little rougher than at first start, but that could just be me thinking about it too much.
