Yes, worn valve seals can indeed cause excessive oil consumption in your Suzuki Alto. The valve seals are responsible for preventing oil from leaking into the combustion chamber through the valves. When the valve seals wear out, oil can seep into the combustion chamber, leading to burning oil and increased consumption.

Symptoms of Worn Valve Seals: You may notice blue smoke from the exhaust, especially during acceleration o r deceleration, which indicates that oil is being burned. If your car consumes a lot of oil without showing signs of leaks, worn valve seals could be the cause.
Engine Misfire o r Rough Idling: In addition to burning oil, worn valve seals can lead to engine misfires o r rough idling as oil affects the combustion process.
Solution:

Valve Seal Replacement: Replacing the valve seals is typically required to fix this issue. This can involve an engine disassembly process, so it is best to have it done by a qualified mechanic.
Check for Symptoms: If you notice blue smoke from the exhaust o r other signs of oil burning, it’s a good idea to have the valve seals inspected.
