Will a Repaired BMW Engine That Took in Water Affect Normal Use?
2 Answers
It generally does not affect use, but it depends on the extent of water ingress. If it was not severe, there should be no issues. However, if it was serious, even after repairs, there may be lingering problems. Repairing an engine with various issues might not be as thorough as replacing it entirely. Additional details: 1. If the engine was not disassembled, there should be no problem, as reassembling a disassembled engine, no matter how carefully done, cannot match the manufacturer's standards. 2. When the engine is at high temperature and suddenly takes in cold water, it will definitely affect the metal strength of the engine, though usually no major issues arise. 3. After being repaired from water damage, there will inevitably be some differences. This depends on whether genuine parts were used and the technician's skill—there might be slight changes in power and noise levels.
I've been driving a BMW for over a decade. If the engine was properly repaired after water ingress, the car can generally function normally. The key factors are the severity of water damage and the quality of repairs. If the engine wasn't running for too long when it got flooded, and was promptly towed to a professional shop for cleaning with replacement of components like crankshaft oil seals and spark plugs, the impact should be minimal. My own car had a similar experience - after repairs, it's been running normally for over 20,000 kilometers. However, it's crucial to regularly check the engine oil color. If it turns milky, it indicates residual moisture and requires immediate attention. Also, ensure cylinder block sealing remains airtight to prevent power loss or even cylinder scoring. Preventive maintenance is vital - pay extra attention to engine condition during every 5,000 km service. In conclusion, with careful driving and regular monitoring, the vehicle can continue running reliably for the long term.
