Choose OEM Engine or Used Engine?
2 Answers
OEM engines are better, but they are more expensive. Engine block severely damaged: If connecting rods and pistons are broken or deformed, and valves are bent, the overhaul cost would be high. In this case, consider replacing with a new engine. If a new engine is too expensive, a used engine could be an alternative. Older vehicles needing engine overhaul: For example, if the vehicle is over ten years old and parts are relatively inexpensive, replacing with a new engine might be cost-effective. If the overhaul cost is similar to that of a new engine replacement, it's better to opt for a new engine or a quality used engine. Deciding between engine overhaul and replacement: Consider both the extent of internal engine damage and the repair value. If the repair cost is nearly the same as replacing with a new or used engine, and the used engine is of decent quality, then avoid overhauling the engine.
I usually consider replacing with a used engine because of budget constraints and not wanting to spend a fortune. A brand-new OEM engine is too expensive, often costing over ten thousand yuan, and there's also the waiting time for parts. Used engines are second-hand units removed from accident or scrapped vehicles, but if you find a reputable supplier and check the engine number and mileage, they can be quite reliable. I often use this solution for my old cars, saving more than half the cost, and they can last several more years without issues. However, don't forget to inspect the engine condition for oil leaks or wear to avoid unnecessary trouble later. In short, saving money is the priority, making it suitable for practical owners like me who don't want to splurge on upgrading the entire system.
