A couple months ago I posted about my Farmall 706 with the 282 glow plug engine loosing coolant. Several thoughts were posted back to me. A common one was the typical bad head gasket of the IH 282 engine. Another possibilty was a cracked head. Anyway I did some trouble shooting today to refresh my memory. I had drained the antifreeze eariler, but put it back in today. With the radiator cap off, immediately at start up continuous little puffs of vapor or smoke would come out of the filler neck. The puffs didn't miss a beat - almost in rythum with the engine. When I just sat the radiator cap on the filler neck (not tight) it would just sort of sit there and bounce slightly - here again somewhat in rythum with the engine. Engine is not missing - runs smoothly. Am I going to be lucky enought to just replace the head gasket? Gasket was replaced maybe 5 years ago when it blew a hole between two cylinders. I did retorque the head when done the last time. Also used copper coat on both sides of the gasket. That time did not compromise the cooling system, just between two cylinders. If I do not find a bad head gasket I assume the 282 heads can be checked for cracks easy enough - magnafluzed? Did the head welding/repair shop in central Iowa close?? Maybe Nevada, Iowa. Tractor does light work such a running augers and mowing. Thanks.
