My 86 Indy 600 has been setting outside in the cold for a couple days and I went to change plugs on it today and noticed some seapage from the head gasket and around one of the head bolts. I have not had any issues with it and am wondering if maybe I can get away with retorquing the headbolts/nuts for the rest of the season. What is your opinion/experience? What is the torque spec for these? The BLOCK is an 83 but it is oil injected so not sure on exact year of whole assembly. Thanks for any input.
