Und was Du schreibst ist auch falsch. Natürlich habe ich die Empfehliung der Werft erwähnt.

Im Gegensatz zu Dir darf ich meine COPA-Posts hier veröffentlichen :-)

The first test was only 40/80 (slightly above master orifice) but a borescope inspection did not reveal any problems. The exhaust valve had a one black spot but all the rest was fine. Oil consumption is low, last oil analysis 25 hours ago was perfect.

After another runup to 300°F CHT the compression improved a bit to 46/80 and the CSC decided that the engine is still healthy enough to be signed off. On the 2:15 flight home all EGTs and CHTs were pretty even, and the engine runs just fine. We decided to check again at the next oil change due in 25 hours.

They said they would never pull a cylinder for this reason and that this would be a waste of money (although they have many used, overhauled and some new cylinders in stock and could replace one jug in 6 hours, They ADVISED me against it.
