Rod, I removed the cover. That’s all. Kept the original paper filter for now. Even without the cover, the filter is perfectly secured and it almost seems like a deliberate design choice to me. Almost like the engineers were like “regulations, you know, but remove four screws and enjoy how it was meant to be”.
As for damage to the engine, I read about that too. Nobody had any evidence to back it up though. That’s why I go with the only data available. The numbers the Pirat pulled, that is.
