What It Means When a Car Engine is Cracked and What to Do About It
Imagine this: you were heading toward York Habitat ReStore to donate some old items that you no longer need in honor of World Upcycling Day. But, on the way your car started smoking and then began to overheat. And what you discovered was a “cracked engine” otherwise know as a crack in the engine block or cylinder head. But, what does this mean exactly, and what does this mean for my engine?
You engine block and cylinder head are parts that are critical to the engine’s structure and function. Because, they contain and manage the combustion process that powers your vehicle. And when these parts develop cracks, it can lead to significant problems, ranging from minor performance issues to complete engine failure. So in this blog, the experts at Meineke on Rodney Road in York explain what it mean when your car engine is cracked, what you can do about it, and how to prevent it.
Causes of Engine Cracks
- Overheating: One of the most common causes of engine cracks. Because, when an engine overheats, the metal can expand and contract excessively. And this can lead to cracks.
- Freezing Temperatures: If the coolant in the engine freezes, it can expand and cause the engine block to crack.
- Manufacturing Defects: Sometimes, a defect in the manufacturing process can lead to weak points in the engine block or cylinder head. And this can eventually crack under normal operating conditions.
- Wear and Tear: Over time, the constant stress and strain on an engine can lead to cracks developing naturally.
Symptoms of a Cracked Engine
- Coolant Leaks: Look for coolant leaking under the car. Because, this can be a sign of a cracked engine block or cylinder head.
- Overheating: Keep track of persistent overheating issues because this might indicate a crack that’s allowing coolant to escape.
- Oil Contamination: If coolant mixes with the oil, it can turn the oil a milky color, indicating a crack.
- Poor Performance: A cracked engine can lead to loss of compression, causing rough idling, loss of power, or misfires.
- Visible Smoke: Look for white smoke from the exhaust. Because, this can indicate coolant entering the combustion chamber. And this is a common sign of a cracked cylinder head or engine block.
What to Do About a Cracked Engine
- Stop Driving: Be warned: continuing to drive with a cracked engine can cause more damage. So, if you suspect a crack, stop driving and have the car towed to Meineke on Rodney Road in York.
- Inspection and Diagnosis: Have the ASE certified mechanic at Meineke inspect the engine to confirm the presence and extent of the crack.
- Repair Options:
- Welding: Minor cracks in the cylinder head or engine block can sometimes be repaired by welding. But, this is not always a permanent solution.
- Engine Block Sealers: In some cases, a liquid engine block sealer can be used to temporarily fix small cracks. But keep in mind, this is a temporary fix.
- Replacement: For severe cracks, replacing the engine block or cylinder head might be the only viable option. And even though this is an expensive repair, it is often necessary for the longevity of the vehicle.
Preventing Engine Cracks
- Regular Maintenance: Regularly check and maintain coolant levels. Also, ensure your cooling system is functioning properly to prevent overheating.
- Proper Storage: During our York cold seasons, use antifreeze and store your car in a garage to prevent the coolant from freezing.
- Gradual Warm-Up: Allow your engine to warm up gradually, especially in cold weather, to reduce the risk of thermal stress.
