Alteration, modification,
or tampering to the vehicle,
including, but not limited to the
body, chassis, powertrain,
driveline, software, or other
components after final assembly
by GM
We know very little about this situation, and have only heard one side of the story (OP's). Do I think that engines have been replaced that have had this modification and others on the vehicle? I do. Does GM protect themselves by having verbiage like this in the warranty? They do. Every company protects itself in this way (I know you know this). We also do not know what testing they have done on "catch cans" and what their reasoning is for not using them on certain applications that could be driving why they took this position. I guess I am still not sure why you think they are hiding behind a moving target when it comes to their warranty when with a statement like this, they have nothing to hide behind in my opinion.
