Yeah, I'll take a picture and post it soon, btw my pathfinder is a 98 and the "leak" is so minor that I havent had to fill the resivor (ever) and the only sign of the leak is some dried up coolant underneath the (plenum between the manifolds) . additionally, I have never had any Overheating issues in the past with my truck! I'm just wondering if this mechanic is just trying to freak me out into getting the work done with him asap ($500 labor to replace a gasket?) because suposedly he saw this before and it could "severely damage my engine". Should I really be worried or should I just monitor it?

Is it common for older V6 pathfinders to have a slight coolant leak from the intake manifold's gasket (under the plenum)? If so, would this cause severe engine damage even if I made sure the coolant were always filled to the top? (I'm asking because some mechanic told me that it would damage the engine if i didn't take care of it now.
