I fired up the TR3 today. It starts good and the engine runs well. After a minute or two I saw white steam coming from the header and manifold side. Took a look under the hood I saw that I had left off a hose clamp at that small hose from the thermostat housing so I assumed that the fan was blowing coolant into that manifold area. Fixed that but when I started it today the same thing happened. Drove a few feet out of the garage and noticed that white steam coming off the header and manifold area. Hard to see the block because of the carbs and heat shields blocking the view. Anyway even though the motor was not really up to temperature I re torqued the head. Going to check the valve gaps tomorrow and then fire it up and see what happens. I suspect the head gasket did not hold???
