goodluck, and do share with us what does your mechanic have to say about the cause of the failure... for my brother's case....his MB100 Diesel block cracked also as mentioned in one of the possible causes mentioned by Niky.... water was sucked in by the Air intake tube...and we know that its incompressible when the piston rises.... so something has to give...its the block that gives normally.

BTW, ano Jazz ng brother mo. Year Model? 1.3 or 1.5; CVT/5AT or 5MT? Odometer reading...
