well guys as the title says, its time for me to get a head gasket. truck started leaking oil from the front of the head about a week ago. not leaking horribly bad, but once the engine warms up and oil thins out itll leak probably about a 4x6 postcard size spot within about 5 mins of turning the truck off. Anyway, ive been told the best route to go would be to replace with an OEM Cummins head gasket and obviously head studs. Im also considering possibly o ringing the head gasket, but i have no clue what that entales, how to go about it, or if any shops around here will do it. So im asking you guys, educate me on o ringing a head/head gasket. Also, curious on what range of money id be looking at to replace head gasket as well as o ring the head/head gasket. Can be what you shop owners would charge, or what you guys have paid as a customer. Just needing to get some numbers in my head. Let me know guys! Thanks!
