Eco diesel coolant leak

[josh flattem]

I need help with my 2015 eco diesel. First this top air intake hose is oily inside and I keep get the code for air intake leaking. This hose does not feel very tight. Second I have a drip per second leak of coolant coming from the radiator hose right below the air intake hose. I’m not sure if the hose is leaking and or the black molded plastic “tunnel / hose” right below it. This tunnel is the one with a blue line on it right below the radiator hose clamp. I don’t know the name for this tunnel thing, please let me know and what it is.

If you had the AEM performed on it, it might be covered by the new warranty. Sorry I can't help with identification but @crash68 is pretty knowledgeable and would probably know. Good luck!

I'm not too sure and can't find another pic that shows that fitting clearly. I found a thread on another forum of someone changing the water pump, I'll send it to @josh flattem

This is the piece I was talking about. It’s hard to see but the second picture show a small hole in the maybe by pass tubing. The third picture is the flashlight shining through the hole. Autozone (only ones open) mentioned to seal the hole with sealant and try that. Not sure if this is a defect caused by the coolant or what. I could see it being a weak point if the pressure gets to high and it blows out. And I will add. My crank sensor went out at highway speed without a load or a trailer but the truck stop and would not restart to cool down. I’m not sure what this part is and if that hole is supposed to be there. Thanks for the help.

I'm getting a leak from the same part. Any one ID the part?

Have you any idea what that black plastic piece is?

If your looking for the above pictured part, it's the water bypass pipe:
