Lycoming publish enough info for a satisfactory break-in, operation & continued airworthiness - is it being read, understood & acted upon by ALL concerned? 6 cylinders a month is a costly way of finding out its not!
It's not being read and probably hasn't been read for years , 95% of the engineers can't read or speak English and here lies an inherent problem for aviation maintenance in Indonesia. Somebody a long time ago translated and read the instructions and then probably didn't agree with it and thought up there own system and that's how it's been done ever since.
The CFI and I used to be on good terms until my recent poking around on this issue , I don't work for the company but I do a lot of business with them including leasing them cargo aircraft and buying their surplus parts and aircraft. I'm trying to help them out but it means a lot of them will 'lose face' with the owner
