actually there has been GM service bulletins on the new 3.5 for quite some time now. Because the cam gears were shearing off and causing a no start condition. seen a few when i was still working at basil. Also in the past 5 months of working where i do now i have seen 2 3.1/3.4 motors come in running and have the cam broken in half. Thanks for the update though Misteroman. :tup:
