The 3.6 DI is basically the same block as the regular 3.6 except with cylinder liners and different heads. I have a Camaro and a 2009 CTS with the 3.6 DI and have not had any problems. You can go to GM's Powertrain website and get all the specs on all their engines and transmissions.

Some time ago, they had a batch of defective timing chains but that was resolved.
