Hi guys,

I'm wondering whether my car to be overhauled or not. The milleage is around 250000km. There's no anykind of white smoke , but the problem is now after a hard drive or long drive the engine seems to be rough and noisy abit, and now I'm thinking maybe it needs an overhaul since the engine is nearly 20years , pls advise on this guys, is it worth it or spend the money somewhere else
