Ricky, I believe that it is the intake manifold gasket. My wifes only had 80k miles when it happened to hers. And I remember filling the coolant up every so often. thought it was just running it out. after about a month I noticed The coolant was going at a rate of about 10 cups in 2 days. then i checked the oil... not milky just look like way to much oil. popped the fill cap and found a little steam. water slowly dripping from the tail pipe. until it got hot then would not drip. It cost $450 bux to fix.
on my old 4.3 before gm redesigned the gaskets they were known to blow which of course mine did and used to use my coolant up quick. once i put the new gm gasket with aluminum siding instead of plastic i never had the issue again...Good luck with whatever you find!

The noise is definetly from the heater core. This is common in most vehicles when air gets trapped in the system from low coolant or a restricted system. If your coolant level is normal you should concider a drain and flush.
