Are you sure that isn't residual oil you're seeing in the coolant? Did you flush the cooling system after the head gasket job?

Wow that's a bummer. Cracked block? Not many places where pressurized oil and coolant interact.

That's what I figured too cracked block the heads are aluminum so they warp before they cracked but actually I just checked and I have all the oil I put into it two days ago so I think it might be fixed it might be residue like the last person said we went and cleaned it out at a car wash it came out pretty gooey but we are not looking at that anymore we're looking at only the oil if I'm not using any of my oil then it's fixed thanks for all your time guys appreciate it

Good deal. Sounds like you got it.

I would do a series of flushes to get the remaining oil out of the system. It can end up clogging the radiator, heater cores and other small coolant passages. There are products you can safely put in and run to flush out the oil.
