Is the Honda 2.4 Engine Oil Burning Easy to Repair?
2 Answers
Honda 2.4 engine oil burning can be repaired. Reasons for engine oil burning: Due to the inconsistency between domestic fuel quality and international standards, a large amount of carbon deposits can easily form in the combustion chamber during engine operation, which is the root cause of various engine problems. Carbon deposits accumulate in the piston grooves, causing the piston rings to stick together, which prevents the piston rings from sealing completely. The "stuck" piston rings significantly reduce the oil-scraping and sealing capabilities. Additionally, sludge can clog the oil return holes, preventing the oil from returning normally and leading to increased oil consumption. Carbon deposits also exacerbate the wear between the piston and cylinder wall, creating excessive gaps that allow oil to enter the combustion chamber. The corrosion and aging of the valve stem seals result in poor sealing. Valve stem seals are arguably the most prone to aging and wear in the engine. Essentially, cars that have traveled over 100,000 kilometers will have this issue. Introduction to engine oil: Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber. It is hailed as the "blood" of the car. Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, imparting new characteristics. Additives are an essential part of lubricating oil.
My Honda CR-V 2.4 has been running for over a decade, and I've encountered oil burning issues. Honestly, fixing it isn't that straightforward. First, common causes of oil burning are worn piston rings or aging valve seals, which require a complete engine teardown for inspection—quite a labor-intensive job. My car had to be repaired twice at a professional shop, costing around five to six thousand yuan to fix, as some critical components needed replacement. If you attempt DIY repairs, the risks are too high; you might mess it up and end up worse off. I also recommend frequent oil changes with high-quality brands to delay this issue. For older Honda 2.4 models, this problem is quite common, so don’t worry too much, but delaying repairs could lead to engine damage, which would be even costlier to replace. Overall, it can be fixed, provided you find a reliable mechanic, with costs ranging in the thousands of yuan.
