Maruti has replaced the half-engine that includes the cylinder block/pistons/crankshaft/connecting rods etc. The leak was from the crankshaft rear oil seal and they will take the faulty halfengine to factory for analysis so that they could find the root cause.
They have allocated their south zone technical lead to work on this issue along with two very experienced technical resources. I have been there personally through the whole process and was impressed with thier dedication to fix the issue.
Bro, I see scratches on the aluminium body near the crank case,
if you claim for the leakage i do not think they will take the responsibility with that scratches, they will claim that the leak is due to the under body hit which produced that scratches.
Is there any more scratches near the crank case?
This leak i think is due to the gasket and can be replaced easily.
