Engine prob on B737
Say your B737-500 is having a major but intermittent oil leak on one of its engines, causing big spills on the tarmac. Mechs simply cannot spot the cause nor the origin as the leak only happens after a fairly long flight. However, they still need to add at least 3 quarts after most 2-3 hour flights. You're told you can still go ahead as oil level and vanishing speed are always within tolerance.
What would you do as a pilot knowing you have no access to any maintenance manual ? Keep going ? Ground the airplane ?
Thx
I forgot to add I need very well backed replies as this is a real issue. I do not have sufficient tools to build constructive arguments. thx
