Hi 3800 gurus,
I really need some input. I replaced the LIM gasket and upper intake manifold with updated GM parts about three years ago. I never noticed any apparent coolant ever since. However, recently I noticed a seepage right on the passenger side seal of lower intake manifold. It looks like coolant with orange color. I marked the position of leakage in the pic.
My question is, is it possible for coolant to leak from that spot, I didn't see coolant passenge in that area? Thanks for any inputs.
