I hv honda city 2009-10 model (manual), day after tomorrow i was leaving for karachi fm islamabad, today i went to honda avenue islamabad for engine oil change, i notice slight oil leakage from engine, showed to to them, oil leakage was not clearly visible, they suspect, its fm cam end cover, from some o ring ,though i order o ring but the problem is they are not sure whether its coming from there, and secondly they are saying spare can take little extra time due to 23rd march prade, i cant wait till that time so i was thinking to leave for karachi and change this o ring in karachi, but scared as what if leakage got increased as family will be travelling with me, so what do u people advise about my plan,and does any one know about such leakage
