Have the same problem. Suddenly started leaking oil, have not had it repaired yet. Should Honda be responsible for this issue?

When I first purchased the Honda Pilot, there was a perpetual leak and smell of burning oil. The dealer at first said there was no problem, but with my persistence, found the block to be porous and they repaired.
oil leaking from the top side of the motor. used dye to track it, but still cant find the area that"s leaking, but still cant find the leak ??? Must be a Honda thing.
Porous engine block...have not yet contacted honda to see about the repair. I feel they should cover it as this is a basic manufacturing defect.
