Odd little leakage

[JwS]

I have noticed a little leakage at the back outside corners of the cylinder heads on my van, it amounts to almost nothing, I mean it barely stains the block. But the interesting part is that when it is cold I have actually seen coolant (if I remember right) bubbling out. Once it is warm it all stops, and I have no problems with coolant loss. But things like this sit in my head, and eventually I need an answer. I have heard of sealing problems back there, but I thought it was only the 6.9's.
Any comments?

Nope, the 7.3l do that as well and it is common too but it can last a long time before that becomes a problem. Check the oil and coolant periodically and You'll be fine.

I would run some Bar's stop leak in it (original pelletized formula). My feeling is that a slow leak will soften the gasket and allow it to grow until you have a complete failure.
