Not familiar with GM products. But I have heard that GM's 3.1/3.4 V6 engines are famous for intake gasket leaks. This would definitely be consistent with the symptoms you describe. Hope this helps.

more likely then not you got a head gasket getting bad , might be in your favor to have it checked out soon before it blows out and does some serious damage, oil and gunk in radiator is not a good sign good luck

Lower intake gasket leaks are chronic on this engine. The gunk in your coolant could be oil that has made its way into the cooling system, contaminating the anti-freeze. But it could also just be gunked up Dex-Cool, which has a tendency to turn to sludge if not properly maintained. Also, while I've seen some bad lower intake gasket leaks on 3.4's, I've never seen one so bad you lose a quart of oil every few days.

If the gunk in the radiator is oil and not just junky Dex, the only other alternative is a blown head gasket.

Assuming the gunk in the radiator is just sludgy Dex with no oil in it then the next most likely place for an oil leak on this engine is the Oil Pressure Switch. This is located just above the starter.

No matter what, get that coolant flushed out, preferably with the GM TSB flush procedure to get rid of all that garbage.

Is there oil on the ground? If not, not a leak.

An intake leak won't cause oil use. Nice guess tho.

Do you have blueish white smoke out the tailpipe?

Crap in the radiator signifies bad head gasket.

first thing check your oil filter most times a rock flies up and pokes a hole in it the hole may even to small to see, change it. It not that costly and it can't hurt.
