dealer says head gaskets

need some advice:

My truck is at the dealer right now. It was leaking coolant out the back of the motor so I brought it in. They found that the hose leading to the EGR cooler was leaking. They replaced that for 700.00 bucks. thought that was pretty high. After they replaced the hose they pressure tested the oil and coolant and said that the oil came in at 15psi and the coolant was 18psi and because they both are not 15psi I have head gaskets going out. I kind of have second thoughts about my head gaskets because it only has 80XXX miles its completely stock and I really don't tow that much with it. I have never seen any white smoke, donít see any milky stuff in the oil and I just changed the oil and didnít see any coolant in the line. I have seen some coolant puke out of the bottle. I friend of mine works at the dealership and I was told they are about to lay off 3/4 of the mechanics because of no work and are really hurting for trucks to work on. So can someone please help me on what and how they should test to see if a head gasket is going out and if you think they are going out on my truck.

could be head gaskets, I don't know much about the testing they do. but the head gaskets are a weak point on the 6.0. I've done my research, because i'm having problems with mine. From what I understand alot of people are doing head gaskets at around 90k. The EGR cooler will give alot of the same signs as bad head gaskets. I put a block off kit on mine. 700 dollars for the hose seems to me like alot, you can get the hose from ebay for like 10 dollars, and all you have to do is turn it like half a turn slide it off and slide the new one back on. If you think the shop is trying to take you for a ride have it checked somewhere else. if you end up doing head gaskets put ARP studs and get the aftermarket head gaskets block your egr cooler and change oil cooler while your in there, then you sould have a bullet proof motor. you can find all the parts on ebay for about 1000.00

If you are out of warranty by time on the headgaskets, and you are not losing coolant out of the degas bottle, i would just drive it. Also the 15psi 18 psi doesnt make sense, The cooling system pressure should not exceed the cap pressure of 18 psi, headgaskets or an oil cooler can cause the pressure to exceed that and indicate a failure (if the EGR cooler is not leaking).

If the oil cooler is restricted it will cause the coolant in the oil cooler to boil and create vapor/pressure, and exceed cap pressure. If the headgaskets fail they will leak combustion into the cooling system only and cause a pressure rise.

If the shop is up to snuff they will have run a UV dye test to find exactly where it was leaking if an external leak was suspected. There used to be some test strips to check for exhaust gases but I haven't seen any for a while.
