    Does anyone recognize this part. Looks important. Just buttoned up the timing cover change job on my 273 and found this part. It has a 5/16-18 screw w/ hardened 5/8" dowel. I know it fits a counterbore on the block somewhere. Got engine running..next morning a few cups of water under car but not sure if the two are related. All water jacket bolts got sealant.

      Dude that's horrible. How did you forget not to put that in? That's at least 5 hrs teardown to get to that.

          Watch out for low oil pressure until you get that back installed. Dude you must be kicking yourself. Like Homer Simpson would say. D'oh!

          Aren't you supposed to have an extra part or two left over? The factory always uses too many.

              Sorry it is not from the car. Checked the thread closer and found it is M8x1.25 so let's put this thread to pasture.

              My guess. The knob off of the handle end of his torque wrench.
