I overhauled engine 2 years back . did not overhaul completely only rings were replaced and it cost me 16000. may be some parts were changed and in 2 years i drove the car almost 40000km. now again engine weak. eating oil, but performance is still good, pick, acceleration, cng consumption. all good. now tell me charges if i go for complete overhaul now. including boring of head.
