Review on Dorman 917 142 Exhaust Manifold Cylinder by Alex Mitra

Used for the second time. First on the 2004 2500HD 6.0L and now on the '06 Suburban 5.3L. The only thing in question is the torque rating of 18 ft.lb. at the central screw that presses on the manifold. I have a pretty good feel for the bolt when tightening and felt like it was tightened before my torque wrench hit the mark. Finally, make sure you have some kind of high-temp threadlocker/sealant before you start. None of these come with braces!
