Your engine block is the backbone of your car’s engine, housing critical components like cylinders, pistons, and coolant passages. When it cracks, it’s a big deal. But how can you tell if your engine block is cracked, and what causes this issue? We break it down below. When you need engine repair or replacement in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive in Mesa, AZ. Signs of a Cracked Engine Block Overheating Engine One of the first signs is persistent overheating. A crack in the engine block can allow coolant to leak, reducing its ability to keep the engine cool. If you’re constantly topping off coolant or seeing the temperature gauge spike, it’s time to investigate. Coolant and Oil Mixing If you notice a milky, frothy substance under your oil cap or in the dipstick tube, it’s a sign that coolant and oil are mixing. This happens when a crack lets these two fluids mingle, which is bad news for your engine. Visible Leaks A cracked block can cause coolant or oil to leak externally. Check for puddles under your car, especially if they’re green, orange, or brown. These leaks may also give off a sweet smell if coolant is involved. Decreased Performance A cracked engine block can lead to low compression in the cylinders, causing your car to lose power, misfire, or run rough. Exhaust Smoke White or bluish smoke from the exhaust could indicate coolant or oil entering the combustion chamber, a common result of a cracked block. Causes of a Cracked Engine Block Extreme Temperatures In cold climates, insufficient antifreeze can cause water in the engine to freeze and expand, cracking the block. Conversely, excessive heat from poor cooling can also lead to cracks. Age and Wear Over time, metal fatigue from constant heating and cooling cycles can weaken the block, making it more susceptible to cracks. Manufacturing Defects Though rare, flaws in the casting process can lead to weak spots in the engine block, which may eventually crack under stress. What’s Next? A cracked engine block isn’t something you can ignore. Minor cracks might be repairable, but in severe cases, replacing the engine or block is the only solution. Regular maintenance, including checking coolant levels and addressing overheating promptly, can help prevent this costly problem.
