Come on - be a Captain (Commander, PIC or whatever you want to call yourself) If you have a technical problem less than 20 minutes away from homebase, there is not much doubt in my mind. Go home, and have it fixed. Management or your customers can say whatever they want, it is still your call.
If it happened 5 minutes away from the destination, you still go home unless you have additional indications of something going really bad.
The Makilas in the L2 are extremely reliable engines, but if you landed, you don't take off with a chip light glaring at you.
