oil in coolant

2002 durango 5.9 blew a heater hose and run hot. replaced hose runs good but getting oil in coolant. doesnt seem to be coolant in oil. could this be just intake gasket.. or head gasket and or cracked heads?

Thanks,

i would start out with a compression test to figure out which cylinder its at, but my first guess would be a blown head gasket. not a big deal to change on the 5.9 since its not overhead cam.

thanks,
i took intake off and cleaned it all up ..didnt see anything obvious other than a broke bolt. but i dont think that was causing my issue..
im this far into it may as well pull the heads and replace gaskets.

check your intake plenum gasket. I had oil in my coolant in my 99 5.2L and went to do head gaskets. Neither one was obviously blown or bad but the plenum gasket was blown out in 3 sections between bolts.
