6.0 burns coolant and coolant in oil?

[mattyt1984]

I have just bought a f 350 dump I just bought it is a 2003 in may not sure of the engine build date I bought it knowing it smoked for 5 grand it has 80,000 miles on it. I assumed it was head gaskets and just replaced both but I saw no sign of that by looking at the head or in the cylinders. I thought that if a cylinder or cylinders was burning the coolant then it would look like it was "steamed cleaned"? It seemed that it would burn more coolant and almost sound like a miss in the engine when engine got warm maybe when thermostat opened? I got the heads back on and torqued didn't bother with studs cause I am just gonna fix it and sell it. Any ideas or anyway I can check the other common problems like the egr cooler or oil cooler?

You should change the oil cooler, egr cooler (delete it would be best), have the heads checked. When the oil cooler gets clogged, it causes the egr cooler to fail. When the egr cooler fails, you will see coolant in the intake (just pop the egr valve off and see if it is wet in there). If coolant has infiltrated the oil, look at the oil cooler. Coolant and oil run through that thing. Most show oil in the coolant bottle when it fails, but I don't see why it wouldn't put coolant in the oil.
It is a chain reaction.... Oil cooler clogs then egr cooler can't pass coolant and it will fail by introducing coolant into the intake, then headgaskets will fail if it is not taken care of.

My bet is toasted Oil/EGR coolers and bad gaskets.

I'd do an EGR delete and replace the Oil cooler (or rebuild it at a bare minimum) while you're doing the studs. When you pull the heads off make sure to have them checked for cracks and straightness, deck them if possible. Same with the block. I have heard alot of guys having their blocks crack in between cylinders.

It won't matter what type of stud or bolt you're using, if you don't have a two flat surfaces to mate together you're gonna have problems later down the road.

Anyway to test the oil cooler and or egr cooler so that I don't just change them for no reason? I just want to sell this truck. I did not see any coolant in the intake or on the head intake ports. And looking at the egr I see that it is pretty clean inside. The coolant was changed at the recommended intervals it was a municipal truck.

Do you have any way of measuring the Oil and Coolant temps?

A way to check the EGR cooler is to pull the EGR valve and see if the inside of the intake manifold is wet but I take it you already did this?
