Mike mentioned the plastic oil filter housing before. Now that's just stupidity. Ok. I can see a heavy plastic cap on a metallic housing, but all plastic?
I've been told from a friend known to have his facts straight, that GM has been putting together study groups to see an assembly's strong points, and to investigate where savings can be made. I bet that housing was intended to be aluminum at one time. I also blame the new age of CAD. IMHO- just cause it's proven on a computer CAD program don't mean it's proven in real life. I dunno. I see some designs and just shake my head.
