What’s up, I’m new on here.
I purchasd a Durango with 208k miles. Bad head gasket coolant and oil was mixing .

i took it to a mechanic to have the heads re done, mechanic tells me it’s done but when I open the radiator cap looks like it’s still mixing ( chocolate milk) ... he told me all that neeeded to be done is a flush of the coolant system, I bring it back to him he calls me and tells me it’s done but he just wants to confirm so he keeps the truck for another week, I call him today and he’s telling me that it’s till mixing that I might need a new motor because he thinks the block is cracked or something . I know it appears I took it to the wrong mechanic. How can I confirm the heads were done and if I need a new motor?

In the picture the the hose that connects to the resi came off and spit out all this stuff... when this happen he came and got it on a tow truck,
