Not sure where the red sheen comes from I don't see it. What I do see is typical oil weep from the intake due to the closed PCV system. Perfectly normal and perfectly harmless if that is what it is.

Water pump is one of the most common leaks and unfortunately often a symptom of a head gasket issue and over pressurization of the system.


On the bleeding:

The bleeder on the stat housing is there as a quick air purge for filling. I fill the tank and wait for discharge here then plug it. I then fill the tank a couple of inches above the midline and go for a drive. Stats open, system burps, and air travels to the tank lowering the level to final level. Let the system cool and top off to just above the midline.
