So I'm thinking to wait a bit to see what happens !

Gen 5 has direct injection, heads are different with the injector in the combustion chamber, variable valve timing with a single cam phaser for 16 lobes, AFM (or DOD) technology carried over from Gen 4.

Each "generation" has had improvements that makes them more costly to produce and maintain.

When will GM be able to produce a roller cam and lifters that will live?

Have one in the shop now with cam lobe failure on cylinder 4, 37000km, this type of failure is completely random.
