I am just lost after what I found. Back around this past 2011 Christmas break I took my 2005 F-350 to the Ford dealer for a trans flush and since I had it there I told them just to go ahead and do a coolant flush on the machine, coolant only had 30,000 miles on it. Well, I then proceed to drive 6 hours round trip to visit my Father for the holidays. I was keeping a eye on the coolant level for the first week and I noticed the coolant started to leave a yellow film in the degas bottle. Then a oil leak starts, looks like it is coming from the top front of the engine by the oil cooler. Truck runs with no problems at all. It had head gaskets, oil cooler, egr cooler, new turbo, egr valve, bed plate leak fixed at 70,000 back in January 2010 under warranty. The truck has 105,000 now and is out of warranty. I took it back to the dealer and showed them what I have found and all they could say is the oil cooler is bad and it needs a new one. Also I have NO coolant in the oil and I flushed the coolant out at home almost a week ago the best I could 5 times with distilled water (with the thermostat in, I was afraid of breaking the bolts), and some of the film has come back but very minimal. Is the cause of all this from the dealer putting too much Ford Gold coolant in my truck back in December or is the oil cooler somehow leaking oil into my cooling system? And if it is the oil cooler can it cause a external oil leak and leak into my coolant at the same time?? Thanks

 

It sounds like the Dealer didn't flush but a couple of times, and surely not until it was clear which can take all day and 15+ full flushes especially if the thermostat and block drain plugs weren't removed.

Do you have a way of measuring ETC and ELC's oil and water temps?

If not that's where you have got to start.

Once you know your deltas are within 15 deg at normal operating temps 192 on ETC you can then begin to diagnose which may involve 40 Gal of Distilled water and a lot of flushing without a Thermostat in.

It doesn't sound like you have a huge issue on your hands.

External oil leak doesn't make it into the oil, so you just have to find the source of the leak.

Hope this helps

Put a coolant filter on it

 

I did right after the flush. Didn't do no good. Sounds like I just need to flush it again and take out the plugs in the block and the thermostat. Should have never went to the dealer for a flush.

 

Should have never gone to the wrong dealer. There are good ones out there. I'm lucky enough to have two good ones within 10 miles of me.

 

So how would a good dealer do the flush better than the one I went to? Would they just leave my truck on the flush machine longer? Just curious.

 

They would flush it till it was clean. I had mine flushed under warranty and never had any problems with it.

 

Gotcha. Thanks. They must have rushed mine out lol.

 

Well here is a update. The coolant really does have oil in it even though the oil cooler was changed back in January of 2010 according to my paperwork. I called the dealer that did all the work the first time and told them that I didn't think that I should not have oil leaking from around the base of the oil cooler and oil in my coolant. They told me to bring it back in for another look, kept the truck for 1/2 of today, and told me they could fix my problems for a little over $4,000 or I should trade the truck in. I told them to forget it and I went and got my truck. Looks like I will be doing a oil cooler real soon.....

 

Sorry Dude, hate to hear that. It would've been real interesting how much they'd have offered you for it, then fixed it and sold it.

I owe about $17,000 on the truck. I wounder too how much they would have given me on a trade. I was looking at new F-150's and new Superduty's, but I cannot see myself going into another 6 year loan for $45-65,000 for a truck that will end up being another problem down the road. I am going to just bullet proof my 6.0 and keep it!!!!
