No problems, no drama, everything is working properly (at least on my red truck) ;)

I'm just curious - there is a sound similar to a vacuum leak when I have my A/C on (red truck). Never noticed if it did it or not before I tore my engine half apart, and I can't tell where it's coming from, just wondering if it's normal? If someone could go check their truck, listen to it running then turn the A/C on and listen for a vacuum-leak sound, it would satisfy my curiosity :flamingo:
