im going to say some of the more common problems with the 6.0s are head gaskets and EGR coolers. . . any other symptoms? any modifications? that will help people as well. . . someone will chime in that knows more about the 6.0 then me.

Oil cooler

That will be the oil cooler. While the EGR cooler leaking is a common problem it will not get oil in the water, just the exhaust system. Oil cooler leaks are also fairly common, I figure someday they will make a recall on em.
We have about 250 F-series superduty's with the 6.0 in our fleet and about half have had oil cooler problems, as well as EGR cooler problems.

Pretty much the same removal procedure for both problems. Remove the air intake and assorted hoses to get to them they are under the intake.
Drain enuff coolant to get below the heads for starters. The oil cooler is the square one at the front of the block.

After about 10 of them it gets pretty easy. Be carefull tightening the intake bolts they are easily broken.

What is the in-service date on the truck? You might still be in the 5yr/100000 mile engine warranty.

in S.E. Texas these will be dealer items only. Your looking at several hundred dollars and about 8 to 10 hours work if you are a first timer. Prices may vary by location, and whether you will be flushing the system, the cooling and oil systems, recomended if this has been going on awhile. Radiator hoses and oil do not get along well if they are saturated awhile. Inner core has been known to seperate.

Also you can get the cooler assembly, or just the exchanger(that part that goes bad) you have to disassemble the cooler to replace the exchanger, but it's cheaper then buying the whole cooler.

I suggest you visit Ford Power Stroke 6.0L Parts Upgrades from BulletProofDiesel.com. We have an online store that has the stock engine oil coolers, gasket sets, high pressure oil pump filters, and upgraded EGR coolers, too (which is easily done at the same time) all at good prices. We also have a link to a DIY instruction set that gives you EVERY single step to do.

Sounds like your oil cooler failed if you have oil in your coolant.
