Some cars will go for many, many years before they give any trouble at all.  With regular servicing and good maintenance, these cars may never have engine problems.  A lot of cars, however, often have particular problems that are typical to the make and model of that specific type of car. We have compiled a list of the most common engine problems that we see on a day-to-day basis.
