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

Not sure where the source for the oil leak that drips from around the oil pan ... but sounds like a OEM issue so I will call my dealer.

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?
