Coolant leak on both sides of air intake manifold
I have a 2002 745i - the only car in the world that combines power, grace, elegance, and beauty - that is approaching 100,000 and as such it's due for some maintenance. While I was perusing the engine bay I noticed coolant on either side of the forward part of the intake manifold - hidden down low in a little cubby hole. I have noticed some minor loss of coolant over the past few months so these two little puddles of coolant are somewhat concerning as they may be symptomatic of a larger issue.
The water pump feels and sounds ok and the coolant transfer pipe weep hole doesn't appear to be leaking - plus they are lower in the engine bay making it hard for it to "leak up" into these two spots (see pictures).
I appreciate any thoughts on what may be causing this. I was getting ready to do the big job of replacing coolant pipe, water pump, thermostat, and a few other items (updated valve cover , gaskets, etc.) but I am hesitant to start until I have a better idea as to what may be causing this.
Thanks for your thoughts - pictures enclosed
