Plastic is crap, and GM should be ashamed of themselves
Cracked intake manifold. The thing is made of plastic, and all that coolant got in my engine. There was no warning until it was too late. A few surges from the engine, then the engine light came on. Then it wouldn't start all in 24 hours.. I took it to get repaired, and it was a $1000.00 bucks. Worried about engine damage from all of the coolant in the engine. Poor work GM to make something important like that be plastic!
Great luxury car, great performance. But now with the cracked intake manifold, I am concerned about unseen engine damage.
Would you buy another car from this manufacturer? No

GM is not the only one to use plastics for the intake manifold. I.e. Ford does too.
If they changed the oil, your engine should be fine.

You're probably okay. An aluminum oil shield is under the intake. It should have prevented any large pieces from getting into your engine, the tiny pieces that are the only ones that might have made it into the circulating oil are your only worry. Just change the oil and oil filter after 1000 miles (or see if they did that during the replacement of the intake), and that should remove any plastic debris from inside the engine. Also, remember that's a 14 year old engine, baby it and it should hold up a bit longer - so no drag racing!!
Shame on GM. WTF were they thinking using plastic for an intake manifold? What graduate from engineering school came up with THAT idea?

I am sure the engineer didn't come up with that. It was more the marketing people that wanted to save a few bucks on every car!
