@jacks2000 absolutely can it be the head gasket. It just depends on where it cracked. Other issues can include a cracked head or even a cracked block. Time to do some diagnostics (at least compression test as well as coolant pressure test) and possibly have the head and maybe even the block fluxed to see if you cracked it. You were obviously pushing a lot of oil into your coolant passages so its definitely something major that will require quite a bit of work
