I used a conventional gasket arrangement with a factory look alike overflow tank and it always leaked. About a year or so ago, I bought a FinishLine Overflow tank that used o rings instead of conventional gasket. It also leaked. In looking closer, I noticed the chrome thermostat housing was slightly warped a bit. You could place it on a flat surface and clearly see where you could slide a piece of paper under the center section, while the ends were firmly touching the table top. I planed down the surface till it was flat, reinstalled it on the engine and it hasn't leaked since........till now. I checked the two housing bolts and they were each about 1/4 to 1/2 turn loose. I tighten the bolts, drove the car once, parked it and it appears to be dry after about a week sitting up. Does anyone know the torque rating for the two thermostat housing bolts?
