oil in anti-freeze

Have 2002 F250 7.3, had oil cooler changed in may of this year, everything seemed fine. took truck for regular maintenance 2 days ago found oil in anti-freeze again,they pulled oil cooler and pressure checked and it shows fine. they seem to think a cracked block, any other suggestions?

i dont see a 7.3 cracking a block,although there is that rare occasion.i would say you have either an injector cup leaking or have head issues...

its not injector cups because it would be fuel in the antifreeze instead of oil how much oil is there in your antifreeze? i had my oil cooler done last year and the shop that did the work said you will never get all the oil out of the cooling system. check your oil level if it dosent go down then you are not leaking oil from your oil cooler

left over oil in the system seems to be what the dealership thinks now.
they say there wasnt as much oil in there as they first thought, so they are goingto re-flush the system and i will drive it and keep a close check on it.

no i never had to add any oil between oil changes, that was one reason i was questioning the cracked block diagnosis.

thank you for your input, i appeciate all help i can get.

More than likly it was the orings. When the dealer reinstalled it I am sure they put new orings in. As you said they probly didn't flush it good enough.
