Did my EGR valve go or did something much worse happen?

[Shinny]

I was driving yesterday and all of the sudden the truck started losing power, blowing blue smoke and bucking. When I pushed the pedal it drove off but had no power at all. It slowly came up to speed. The smoke stopped after a few minutes. I took it to the dealer and they can't look at it for at least a week. They told me it sounded like and EGR valve, leaking head gasket or intercooler. What do you guys think?
Thanks

I have a friend that was told ...the inter cooler caused his 6.4l engine to blow...There is coolant in the oil so a new rebuilt short block was ordered. I don't understand how a inter cooler can cause a engine to blow....I think it was the EGR...There was no coolant in the degas bottle....I'am leaning toward the EGR....not a head gasket or inter cooler. Godd luck, hope you get the truck back soon...

doesn't the Job 1 EGR when stuck allow coolant into the motor?

The dealership said it'll be a week before they can look at it and a week to fix it. I'll post pics of it when the cab comes off.

The EGR only recirculates gasses back into the intake from the exhaust, no coolant actually hits the EGR valve ( by design anyway) unless you have a bad cooler and it leaks internally. Good luck.

Coolant does run through the EGR valves on these motor and if they fail the valves will allow coolant into the EGR coolers.

Tha EGR valves do not have coolant going to the, the intake manifold does but coolant does not touch the valve.

Here is a Intake cut out:


And an EGR valve:


Just for those who have never had one out.

The smaller is where the EGR goes and the learge port to the left is where the intake elbow mounts.

Last I checked the EGR valve that was pulled out of my truck has coolant lines.....maybe I got lucky. If you'd like a pic ill post it in the morning.

I have never pulle done on a 6.4, what I posted was a 6.0. I have pulled countless 6.0 valves and have never ran into one with coolant going to it, that's all. Just offering up some info.

How does the dealership check the EGR, intercooler for defects. I have a job 1 and when ever it rains i get white smoke and hesitation. Dealer told me that it sounded like EGR problem but they had to see it happen and i dont have time to stop by and pick up some mechanic on a rainy day and hope it happens. Herd an EGR valve is 50 bucks should i just have them replace it?
