No pictures yet - it may be a few days

Haven't heard it run - bought it today as a "barn find"

Previous owner says it has typical blown head gasket and ran with "white smoke" :

"The reason for blowing headgaskets was due to Toyota only torquing the headgasket from the factory to 56-58 ft lbs. This torque spec would have been more than adequate for the asbestos HG that was originally intended for the engine. Since Toyota did not switch the torque spec to roughly 72 ft lbs when switching HG material, every 7M that is left untouched is doomed to a fate of a 'BHG', usually between 125,000 miles and 175,000 miles. A correctly torqued OEM HG will last as long as the engine will."
