See photos of my inlet manifold, coolant leaking from bolt, can it just be tightened or is it something more...
This is just a guess as it seems that none of the other, more knowledgeable forum members have posted. I have seen a few other posts talking about this problem and it seems that the VTs have a mild problem with their inlet manifold gaskets. Change them and while you have it apart, look for cracks and corrosion. Hope it all turns out well for you.
Make sure you give the area a thorough clean first.
Don't want any of that shit dropping into your intake ports or cooling system.
