Problem with the rod valves

08-15-2014 10:11:22

We have a R22 Beta II with 400hrs TSN. Yesterday we grounded this one for the 100hours inspection, the maintenance found a prematurely wear of the escape and admission valves rod.

We have registered similar situations with the rod premature wear here in Brazil that even after changing the rods and rocker assembly, there's still an excessive and premature wear.

So we'd like an opinion and know how about this problem with the O-360 with the new valve system. Why does it happen? How? Are there other engines with the same problem?
How to solve this issue?

Follow attached two pictures.

Thank you!
