I cannot comment with any authority on what GM will or will not do regarding your warranty, if you install an oil catch can. My layperson opinion is that an oil catch can won't void any warranty. You could contact in writing the GM Regional Customer Service Rep in your area, and ask the question. Give the Rep the specific information on your planned oil catch can purchase in your submittal, and ask them to state whether or not the installation of an oil catch can will void your warranty. They are obligated to respond to you in writing, though there is no guarantee that their response will be definitive.
I purchased a JLT oil catch can from Summit Racing for $149, and I am fully satisfied with it. The instructions were clear, and they covered more than one generation of truck, so that it was clear what needed to be done, regardless of your model year with their slight differences in plumbing. The kit included everything that was needed, and I did not have to cut any of the supplied hoses to make it fit - truly bolt on. That said, there is no rocket science behind the design and operation of an oil catch can, and I am reasonably sure that the $30 oil catch cans sold on Amazon will accomplish the same objective.
