You know the tonawanda plant has been assembling engines for GM since 1938, right? Politics aside, as much as i really hate liberals, that does not mean politics involve issues with engines due to an issue involving part sourcing. They assemble the engines with the parts they are provided. The issue has been the parts they have been sourced. If there was an issue with the liberals assembling our engines for us, it would have popped up since 1938 already. But here i am talking to a wall again. Can only provide so many facts before you go "but muh dodge" when they have the same lifter issue.
