Gray035 is on a distinguished road
Well unfortunately my misfire is back. Still the fifth cylinder with fuel cutoff.

This led me to do a leak down test. The fifth cylinder is leaking into the fourth and sixth cylinders (about 30% or so). Oddly, however, the fourth and sixth cylinders aren't really leaking into the fifth cylinder (they both have a loss of less than 10%).

This leads me to believe that the head gasket is the fault.

It seems odd to me that the fifth cylinder is leaking into the others, but the others aren't really leaking into the fifth cylinder. Has anyone experienced this before?
