Oil in coolant
Today, I drained the coolant in my '97 F-250 PSD to change some hoses and now the pan that I drained the coolant into is about 1/2 covered w/ what I assume is oil. Now, I'm not as experienced with diesels as I am w/ gas engines but I'm guessing that this is bad regardless of which fuel you use. My questions are: Are there coolant additives that will make it seem like there is oil in your coolant and if not what is the most likely source? I would hope that it is the oil cooler but I assume that is not likely. Also, if it's a head gasket issue, is there any way to determine which side(no spark plugs , no compression check).

First thing I'd think is injector o-rings. There's a post i read a day or 2 ago that explained real clearly - but basically there is oil, fuel, and coolant flowing around your injectors - each seperated by o-rings on the body of the injector. The coolant is at the lowest pressure - so when there's a problem - either of those other 2 end up in your coolant. How many miles are on the truck??

Mine was the oil cooler. I replaced the O-rings in the oil cooler and still had a leak, replaced the whole cooler and it was fixed. I was told by my local radiator shop that it was a common problem, me had already replaced 3 in other trucks.

I'm the poor shmuck who had to deal with this last weak I posted "black sludgy coolant" I had a major leak I was acumulating several inchas of oil in my over flow res. I repalced both injector orings and the whole oil cooler. My guess is the oil cooler was the culprit. I would go there first. it's not too bad of a job. the oil cooler has a lot of oil and coolant only seperate by 1 oring also the cooler it self could be dmaged intenaly. good luck J oh yeah I have a 97 too.

It's not too bad of job. You will want to take off the inside fender cover and use about 1.5 feet of extensions to get the front bolts off. Then it is tricky but possible to finagle the oil cooler out in one piece,( i had lots of practice, 3 times). The job will only take about 20-30 min. There is a little valve that is on the oilfilter side of the cooler, be careful not to loose it.
