Was getting our Palio D serviced the other day and i came across another Palio D which had come to rectify a blown head gasket. This Palio D had 7,66,728 km's on its odometer. That's a very, very high mileage for a non-taxi vehicle. Barring the usual wear and tear, it seemed fine. And the mechanic was confident that the engine is good for many more km's yet. He did not have any info whether this engine had been rebuilt or not. But i reckon it would've been rebuilt once for sure.
