05 equinox w/ antifreeze in oil

Sounds like the head gasket has failed, but you need a shop to double check the intake gasket to make sure and you don't want to keep driving this because the oil pump is pumping contaminated oil throughout the engine and cause further damage

same happened to me...turns out it was the head gasket

racked head or gasket probly exzaust port thats how coolant is getting out or your oil pan is full of coolant
