Buick Excelle engine oil leakage can be addressed by: 1. Identifying the cause of the issue before proceeding with repairs; 2. Replacing any damaged components; 3. Tightening the nuts. The Buick Excelle 2019 is a compact 4-door, 5-seater sedan with body dimensions of 4609mm in length, 1798mm in width, and 1486mm in height, with a wheelbase of 2640mm. It is equipped with a 1.0T turbocharged engine and a 6-speed manual transmission, delivering a maximum power of 92 kW and a maximum torque of 170 Nm. The vehicle features front-wheel drive, with a front McPherson independent suspension and a rear multi-link independent suspension.

My Buick Excelle also had an engine oil leak last time, which was quite alarming. That day, there was a pool of oil stain under the car. After checking the information, this is commonly caused by aging of the valve cover gasket or failure of the oil pan sealing ring. Prolonged exposure to high temperatures can make the rubber brittle and lead to oil leaks. I immediately stopped the car to check the oil dipstick, and felt slightly relieved when the oil level was normal. Don't rush to drive; wipe the oil stain dry with a cloth and observe for a few days to confirm the exact location of the leak. If it's just a minor leak, replacing the new sealing components will solve the problem, with costs around 500 yuan at a 4S shop. However, if the leak is significant, you should go for repairs immediately; otherwise, insufficient engine oil may cause more expensive engine damage. I went to a professional shop to have the sealing ring replaced, and it has been working fine ever since. Regular oil checks are essential to prevent future issues.

I always fix my car myself, and dealing with oil seepage in a Buick Excelle engine isn't too difficult. Common leakage points are the crankshaft oil seal or valve cover gasket, where rubber aging causes poor sealing. First, turn off the engine and wait half an hour before crawling under the car to check for leaks; oil stains may accumulate around screws. Try gently tightening the screws to see if that resolves the issue. If not, clean the surface, spray some degreaser, and observe for a few days. You can replace the seals yourself, but make sure to buy matching parts to save money. If you lack experience, it's safer to visit a repair shop—material and labor costs combined are usually affordable. Regularly maintain and inspect the lifespan of seals, and top up the engine oil promptly if levels are low to avoid major issues.

After years of driving Buick Excelle, oil leakage is common, mostly due to aging gaskets and poor sealing. Engine operation causes thermal expansion and contraction, leading to oil seepage, especially near the oil pan and valve cover. Don't ignore oil leakage; driving with it poses high risks, significant oil loss, and even higher engine damage costs. It's recommended to park the car and have a professional technician diagnose and replace the sealing components for a quick and cost-effective solution.
