Hello, I am thinking of buying honda civic 1.8 petrol around 2008-2010 and my concern is how reliable the timing chain would be on this engine. Previously I owned honda accord 2007 2.2 ictdi and on this engine the timing chain failed at 80k miles. Started making very loud rattling noise when engine hot. After going to the service, mechanics told me that this is the week part of honda cars. So again how often is this failure is on petrol engines? I just read one advert selling car and the seller claims that chain needs changing. Car has just below 70k miles. How much it cost to replace?
