Oil in Coolant

[willdocter]

Hey guys,

I've got an 04 6.0L with the 03 engine and the truck is puking coolant for the third time in its life. Symptoms are;

puking coolant
oil in coolant
no heat (last week, i had heat but only when revved, not at idle)

I've already replaced the res cap, water pump and thermostat. Also deleted the EGR and had a reputable shop install new head gaskets and ARP head studs.

Are these symptoms of the oil cooler?

Oil in coolant is usually a sign of failed oil cooler. I had the same problem with mine. I never puked coolant though, and had heat.

Oil cooler and EGR cooler have ruptured and need replacement. You may have other issues, but those specific parts ARE bad and will require replacement before you can troubleshoot further. If you are a DIY'er you can tackle the replacement yourself. You might consider the semi-BulletProof kit from BulletProof Diesel BulletProofDiesel - Darn-Near Bullet Proof Diesel Products for your 6.0, which is a replacement stock oil cooler with their upgraded EGR cooler and all the gaskets to replace them.
