A rebuild because of bad valves? And yes, the compression values are all over the place. That is not indicative of bad rings. My Corolla had bad valves too, got brand new OEM and the car was as good as new, returned 14kmpl in city.
Anyways, Irshad has become like Afzaal now, monkeys with wrenches who consider people their ATMs. Not entirely different from the herd.
