engine oil entering into coolant - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I have a 2004 F-250 super duty with the 5.4 engine. Engine oil is somehow getting into the coolant and I have not been able to pinpoint where it is coming from. Is this a common problem on this engine ? I have had the engine oil cooler and the trans cooler part of the rad pressure checked and they were OK. I went as far as removing the heads to check the head gaskets and there were no definite telltale signs. NOW WHAT ? Any suggestions would be greatly appreciated.

Are you sure it's Engine oil? It could be trans fluid from a bad radiator.

Yes, I was told it was definitely engine oil by the guy at the rad shop

And the head gasket looked good? While you had it torn down, I probably would have replaced it. Curious to see what the problem is.

yes, the head gasket looks good and it will be replaced, never one to reuse old head gaskets. Had the heads sent out to the machine shop a few days ago. This is the first time that I hope they find something, if not, I guess the block will be going next.

Yeah this is strange. Normally its the other way around. My first thought was the same as an earlier post, transmission fluid. I hope its nothing to bad. Please post your findings though. Its got me curious.
