Where are the common oil leakage points in the older Cruze models?

The area where the engine oil filter is installed in older Cruze models is prone to oil leakage, and the valve cover gasket is also a common source of oil leaks. If oil leakage occurs, immediate repair is necessary to prevent affecting the engine's normal operation. Here are some related details: 1. Engine Oil: Engine oil is often referred to as the lifeblood of the engine. Without it, the engine cannot operate properly. Engine oil serves multiple functions in the engine, including lubrication, cleaning, sealing, buffering, rust prevention, and heat dissipation. 2. Principle: When the engine is running, the engine oil forms a thin film on the surfaces of various components inside the engine. This prevents direct contact and friction between these components. Direct contact and friction between engine parts can accelerate wear and may also lead to engine overheating. 3. Regular Replacement: It is essential to regularly change the engine oil during vehicle use. Additionally, the engine oil filter should be replaced every time the oil is changed. The oil filter is responsible for filtering the engine oil; without it, the oil can become dirty over time, which can impair the engine's lubrication and cooling capabilities.
My old Cruze was leaking engine oil recently, which really worried me - there was a big oil stain on the parking spot. Common leak points include: the oil pan gasket (aging or improper installation causes seepage here), the valve cover gasket (engine heat hardens and cracks the rubber), front/rear crankshaft seals (worn seals allow oil to seep), poor sealing around the oil filter base, and the engine oil pressure sensor (aged sealing rings cause leaks at the connection). I've had it repaired several times - untreated leaks waste oil and can cause engine damage from oil starvation. It's worse in winter when gaskets shrink from cold, increasing leakage. I recommend checking for undercarriage oil stains every three months - early detection prevents major repairs. Always use OEM parts - a properly replaced gasket can last 2-3 years.
I'm in auto repair, and oil leaks in older Cruze models are quite common. The main trouble spots are: the oil pan gasket is the most prone to failure, often due to rubber aging and shrinking or improper sealing; the valve cover gasket frequently leaks due to heat-induced deformation; both front and rear crankshaft seals are susceptible to leaks, especially in vehicles over 100,000 kilometers; a poorly sealed oil filter base leads to noticeable seepage; and aging gaskets at the oil pressure sensor interface are also common issues. Prolonged oil leaks can contaminate the exhaust pipe, increasing fire risks. For minor leaks, replacing the gasket usually does the trick, but severe leaks may require engine disassembly, which is more costly. For prevention, regular maintenance with a mechanic checking the undercarriage and inspecting seals during each oil change is key. Some areas in the Cruze design tend to accumulate heat, accelerating aging, so timely repairs can extend the vehicle's lifespan.
