The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

Camaro started overheating. Checked why and noticed there was NO coolant so I filled it up and about a month later it happened again. All the coolant was gone! Finally took it in to the dealer and they said this was the problem. They checked for leaks and replaced the leaking intake manifold gaskets and rocker cover gaskets. This did fix the problem, but I would recommend shopping around first. The dealer is a total ripoff. Took it there because a friend worked there and could get discounts on the parts. Ended up paying 153.73 for parts and a whopping 914.17 for labor for a grand total of 1067.90. I now go to American Tire Depot for repairs and maintenance stuff, I can't speak for all their locations but at the one I go to (Murrieta,CA) the people are nice, actually get to know you and knock off labor and stuff.

Oil in water. Spitting water around intake.
Discovered yesterday my Camaro has this SAME PROBLEM! But has been leaking antifreeze for about a month now but never could find where the leak was going. Checked the antifreeze yesterday, almost completely dry! Added more & immediately checked oil and it ALL had went into the oil. So now my 2002 Camaro is outta service till its fixed! My dad use to be a mechanic so he instantly knew what the problem was, lower intake gasket blown.

I have the same problem. My local chevrolet dealership did a pressure test and found it leaking at the intake manifold, also the timing cover may leak a little as well.
I had a lead onto the garage floor - wasn't sure what it was exactly. Seemed like water, not oil. A few days later the heater/defroster was blowing cooler air & after shutting it off for a while, it blew warm air again, but turned cooler after 5-10 minutes again. This repeated. The car did not overheat. Temp gauge read normal at all times. The shop says the intake manifold gasket needs replacing as coolant was leaking & some was getting into the oil. The internal coolant leaked causing coolant to mix with the engine oil. He also said that operating the engine with a coolant/oil mix can result in internal engine damage. I am replacing the intake manifold gasket at a cost of $721. They will have the car 2 days.
