Thanks

If it is a Stovebolt six, they were produced long before "stretch" or "torque to yield" bolts were invented, so don't worry about it.
If you have something that is relatively late-model, best to check a repair manual. | | |

there were traces of water on the oil cap and when you take it off you canput your finger on the rocker arm and theres white snotty stuff that comes off of it. You think a blown head gasket is what is causing it?
