Just a quickie to say hello again and report on a good result to changing the head gasket and water pump on my 1981 TR7. Had, since the rebuild of the engine 30,000 miles ago, been getting combustion pressure in the header tank, with resultant loss of coolant. Lived with it for 5 years and 30,000 miles until it started putting coolant into the crankcase at a fast pace. Head came off easily, gasket blown at rear of cylinder 4 into water jacket and apparently had been that way for some time. Head torqueing ritual had not been followed after rebuild. (my bad) Replaced head gasket, O-ring, and water pump. Performed head torqueing ritual, and will torque again at 500 and 1000 miles. Result is, no combustion pressure in system, no coolant loss, and no overheating tendancies. Must now check thermostat for sticking, as it takes forever for it to warm up. Cannot see any reason for the water pump to be leaking, but read a warning somewhere about soft shafts that wore rapidly and leaked. As usual was sorry I had put off the job for so long as it was only the usual bother and not the unusual bother. If I was to do it again I would use the reccommended alignment studs for mounting the head and pay closer attention to the distributor clip that got under the head on the first attempt. All in all a good result and we are looking forward to traveling in the 7 to Tucson on the 28th of this month.
