Coolant leak

I have been wrenching on my 04 f250 cc (early build) for the last couple days now and have the following issues.

There is coolant leaking down the passanger side of the block dripping off the starter and it happens when i stop and the truck is cooling off. I have read that it may be the old orange hose on the egr cooler, but mine has the blue one. There is a lot of fluid in the valley of the block almost like that blue hose is failing but i just am not sure, also when I get down and look up at the block from underneth, it almost looks like the head gasket could be leaking externally, is that possible? I havent had any pressure testing done yet (wich I should have done that first) but also I have already pulled my turbo to investigate and was just hoping to find a answer like maybe the cooler is bad and I can replace it before I put the turbo back on I dont know, hopefully you pros can help a poor guy...

my truck is bone stock, no tuner, no mods other than the zoodad..

Thanks all!

also look at the heater hose that passes right by the alternator and along the top of the valve cover goes threw the fire wall to the heater core

Thank you so much for responding. I have checked the heater hose lines and it doesnt seem to be leaking. A few months ago I flushed out the coolant and replaced it with the ford gold stuff, I dont know if that makes any differnce but I thought I would throw that out there. I was also wondering if any of you guys have seen the coolant leak out of the oil cooler? It almost seems that coolant is running down the back side of the valley and down both sides of the heads and eventually dripping off the transmission. It looks like that is where its coming from and I would like to delete the egr, put a new oil cooler in and was wondering should I flush the coolant and replace with any differnt kind of coolant?

Thanks so much for all of all of your input...

Just want my truck healthy bad, and Im sick of driving the wifes car!!

if its any were near the oil cooler then it should be the egr cooler to oil cooler hose. that hose is either orange or blue and about 2" long. the blue one is the updated part.

Thanks again for the responce, I really appreciate it. The hose is the updated blue one and it does look like it is leaking from that spot but I was wondering if the oil cooler was plugged and would cause the egr to start leaking from that blue hose? I would like to delete the egr completely and was also wondering if the CEL would be on due to the delete? my truck is a early build 04 with no tuner...

Thanks again
