Today I just replaced the head gasket in my 1946 model A and it is already has a couple of external coolant seepages. The head has been milled flat, torqued all the nuts evenly to 80 Lbs. Cleaned the block deck and head surface. Used a die to chase the studs and replaced all the head nuts with new ones. I torqued the head nuts in four steps too. I installed the gasket dry without sealant as I have had trouble with gasket sealants.
Now I have not run the tractor yet or retorqued the head. Is it common for new head gaskets to seep until after a heat cycle and retorque? I have read that with old engines it can take 3 or 4 retorques to fully seal them up and completely stop seeps. This is the third time I have replaced the head gasket on this tractor in 5 years. The other two times I used gasket sealant and hoped to have better success without it this time around.
