Just test drove a 2007 with 58k miles, the ficm was 47.5-48 and ficm logic power was 12.5-13. The eot and ect was 2-7 degree difference periodically and was usually at ect 191 roughly and eot was 195-198. There was a little white residue around egr college cap but not much. How does the truck sound, plz give me your input , thanks. Gonna ask for a carfax and oasis report now. Thanks.

You could also check for exhaust gases in the cooling system, that will tell you if the heads are blown/leaking. Otherwise those numbers look good. I dont know where the coolant is leaking in your description.

I meant the egr coolant cap, sorry it was a gold coolant to :/ how do I check the exhaust gases??? Thanks guys

You can check for exhaust gases in the cooling system with a block tester from Napa. Its a blue fluid you put in a vessel that sucks only the air from inside the cooling sytem, if it turns green, there is exhaust in the coolant.

Don't ignore these tests. Trust me, it gets expensive quick. Tests are cheap.

i am not very mechanic like with working on engines and seems a little confusing, it sounded wierd idling at first back by the exhaust tip like there was a turbo leak or something but i have no clue what that sounds like... i have a duramax so its not even close. we took it for the drive and seemed fine idk

Whos selling the truck? You can also take it to a Ford dealer and have them run a diesel diagnosis test, that will tell you if anything is wrong with it before you buy it.

Mine has a turbo back 4" exhaust with a cat delete. I can hear the hissing you are speaking of. You probably hear the turbo going through it's paces as well. It's a sound conduit, a wave guide. You probably won't hear a turbo leak back there. It might be obvious under the hood though. If you have good boost when you romp on it on the hiway, especially uphill (20 - 30psi) you are probably ok there.

EGT/EOT different and the coolant puking are very important. Get the test for head gasket integrity. Look for trouble codes as well.
