Below is the best photo I could get of the cam on the TSIO-520NB engine.
While not the best photo, if you look closely there are three different colors of metal showing, and some galling.
This was taken through the hole where the cylinder belongs.
Parts are not available for it at this time. Ram engines will not release a replacement cam to other builders (who do have cylinders) and they claim that they do not have the cylinders to do a rebuild. We are looking at possibly doing an IRAN instead, and are awaiting a quote from Ram Engines.
On the other hand, the rest of the annual inspection is going well so far.
