The further we got in to it we realized it had more than likely that it over heated at one point and cracked a head. I got it at about 32k so it's possible. The driver side (good side) had a different valve cover bolt and was missing a bolt on the power steering pump, not probable from the factory. Plus the pistons on the drivers side 5 6 7 8, which you can see In the pic are spotless compared to the passenger side. I don't know, but it's fishy
