  1. Notice how no one in this commercial said anything about the EGR or regen cons?? I’ve seen this crap engine require total rebuilds every three years.

  2. I thought this was gonna be a video on how injectors work or something but it was actually a video advising you to go to a stealership to spend 1000s if dollars on changing all of your injectors

  3. This is a volvo engine. The whole truck is a volvo with a crappy mack cab on it with everything done ass backwards and poorly designed.
    The only thing mack about the mp7 and mp8 are the mack lettering on the valve cover.
