The engine is one of the most vital parts of a vehicle. How long it lasts can range from a couple of years to the lifetime of the vehicle.<\/p>\n\n\n\n

This component reached its limit on a 2014 Jeep Grand Cherokee.<\/p>\n\n\n\n

In addition to its check engine light turning on, the vehicle hesitated when accelerating. A tapping sound could be heard from inside the engine, as well.<\/p>\n\n\n\n

Checking the spark plugs was the first step for the technician. During a diagnostic test, there was a misfire on one of the cylinders.<\/p>\n\n\n\n

Misfires<\/strong><\/a> can happen when there\u2019s an excessive amount or not enough air or fuel. They may be caused by bad spark plugs, ignition coils, timing belt or fuel injectors.<\/p>\n\n\n\n

The Jeep was also in need of an oil change. When he was removing the oil, the technician noticed metal shavings that resembled glitter. This led him to believe that the issue laid deeper.<\/p>\n\n\n\n

Sometimes, metal shavings in oil mean that there\u2019s a design flaw. It can also be a sign that certain components \u2013 like the timing chain or intake or exhaust valves \u2013 are experiencing wear or that maintenance is needed.<\/p>\n\n\n\n

Other signs that a new engine is needed<\/strong><\/h2>\n\n\n\n

Misfires and a car that seems to be struggling to accelerate aren\u2019t the only symptoms you may notice when it\u2019s time for engine replacement.<\/p>\n\n\n\n

Knocking noises can be heard if you need a new engine. Certain codes could appear, too.<\/p>\n\n\n\n

There\u2019s no code that tells you that you have a bad engine, but codes can serve as a starting point and indicate related problems. These include knock sensor codes, codes associated with timing and cam position, misfire codes and cam and crank correlation codes.<\/p>\n\n\n\n

Shuddering, a car that won’t start, and smoke coming from the exhaust are other possible signs that engine replacement might be required.<\/p>\n\n\n\n

A flashing check engine light is another indicator you should be watchful for. When this happens, the vehicle could be telling you that there\u2019s an engine problem. You shouldn\u2019t drive it if the check engine light is flashing.<\/p>\n\n\n\n
