Coolant leak question

Hey guys,

So I have a small coolant leak that appeared sometime today. The trucks been sitting for 24+ hrs and it just showed up.

Anyways, so the pass manifold is wet, and it looks like its possibly coming from the valve cover above the rear most glow plug on that side. I know that no coolant flows through that area, so any thoughts on where its coming from?

I'm removing the wheel well cover to get better access and I'll get pictures up asap to help.

Thanks for the thoughts!

It could be the egr cooler connection leaking and just making its way down there. Just a thought.

That's a good thought. I'll check it out again, but my first look up top looked dry..

I don't think it's the heater core or lines, all of those are dry. So is the entire back side of the motor. It seems to be seeping from the valve cover gasket, down to the GP buss, then to the manifold, starter, trans cooler lines and to the ground. The head don't appear cracked from the outside (they were magnafluxed and checked when I had my studs done).

My oil doesn't grow, nor is it milky, and I don't have any over pressurization of the cooling system. I haven't noticed my coolant dropping at all and my exhaust smells normal.

How likely is it that the GP cup is cracked letting coolant seep out pass the o-ring?

The area above the valve cover is dry. The upper most place where it's wet is at the valve cover gasket, and it seems to be confined to just the one GP

Did you try tightening down that bolt?
