Leaking head gasket?
Hi, this is my first post but I have been using this forum for information for a while now. I have a 1987 gmc v2500 5.7l. My issue is that my coolant turned from the normal slightly dirty/rusty to black with a touch of green from the Prestone within a couple of days. I noticed I had lost oil...- youcancallmedusty
