Engine identification can take place using various methods. The VIN, described earlier in this section, contains a code indentifying the engine originally installed in the vehicle. In most cases, this should be sufficient for determining the engine with which your car is currently equipped. However, some older vehicles may have had the engine replaced or changed by a previous owner. In this case, the engine can be identified by an engine serial number stamped on the block or located on adhesive labels that may be present on the valve covers.
