    Had an oil leak. I put a bottle of "Blue Devil" and replaced my oil drain plug and no more leaks

    Not fixed, yet, but oil leak from under the timing cover attempted repair by reputable mechanic. Same oil leak. We've taken it in 3 times and so far no luck on repair.

    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.

    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.
