Unhappy coolant in oil????

Need some help from you 6.0 smart guys. I searched the forum but didn't really fine the answer.

My wife has an 05 f250 6.0l that has started loosing coolant. No evidence of puking out the degass bottle.

I only blows steam when starting and letting off the throttle after acceleration when the truck is at operating temp.

I just drained about a quart of coolant out of the oil pan.

What is causing this? Head Gaskets, heads, EGR cooler, oil cooler, cracked block, chick driver ??

Truck has 125 k on it, completely stock. I'm assuming any of these will cost me at least 2-3k.

I want to be informed before I go to a shop to get it fixed.

Thanks TJ

i had a similar problem with my engine, its a 05 too, engine never ever puked coolant any time it just had brown stuff in coolant bottle and more than normal fuel in the oil 8% fuel. my problem was a bad clogged egr cooler, egr valve, oil cooler, 2 new injector o rings new degas bottle, all new coolant hoses all around and engine oil flushed 2x and coolant flushed 4x to purge any remaining stuff in either of them hope this helps to point u in the right direction, all done for a 100 dollar deductible by my dealer called Allegheny ford in Pittsburgh, they treated me good got the truck back in 2 days cant ask for more from them.

if the oil cooler leaks or cracks it will cross contaminate the oil and visa versa this may be the reason u are getting coolant in oil.

thanks for the response, got a new issue now....the truck wont start. turn the key and...klunk...I assume thats whats called hydro lock?? Only tried it once so hope I didn't damage anything.

truck is out of warranty.....got two estimates $3500, $3000 for replacement of either head gaskets, or EGR system.

If you are getting coolant in the oil, stop driving it immediately. Coolant can do a lot of damage to bearings fast.

Hydro lock is usually caused as a result of bad heaqd gasket which can also cause coolant in the oil.

Thanks The truck has been parked since discovering the problem. A Ford dealer here in Tucson seems to think it's probably the EGR or Oil cooler. Either way they quoted me approx 3 grand to fix. Told them I was active duty military, they said expect about 1grand less. Hope they follow trough with that.

Trucks going to them Monday.

Thanks again

I have to agree with jerzydiver that it is more likely a head gasket. The oil pressure is much greater than the coolant pressure, so if an oil cooler was bad you would have oil in the coolant not coolant in the oil. Also you mention no oil in the degass bottle.

No oil I can see in the degass bottle, just coolant. The tech said he doesn't see allot of head gasket problems with the symptoms I described. He said it sounded like an EGR cooler failure. Either way its expensive.
I should have bought the extended warranty.

You could pull the egr and look for moisture in the intake. If the EGR cooler was leaking there would be coolant on the egr valve and inside the intake.

Found out today its the EGR cooler is fried. 3500 bucks to repair with parts and labor. The cut the price down to 2000 for military discount. Still expensive.
thanks for the replies
