2013 Ford F350 with a 6.2 had a misfire on cylinder 8. Ended up being a broken intake valve spring. Pull the valve cover, coil, spark plug and rocker shaft off the affected side of the engine. Install either rope into the cylinder or use a compression fitting to apply air pressure to cylinder whil on top dead center and the use a valve spring compressor to compress the spring. Once the spring is compressed enough you can remove the valve keepers fron the valve and remove the spring. Check the valve seal for damage as the broken spring can tear the seal. Install the new parts in reverse order.
the torque spec for the rocker shaft is as follows.
step 1 - 10nm(89inlbs)
step 2 - 20nm(177inlbs)
step 3 - tighten additional 60 degrees
