Just the luck of the draw kid.

std engines have been known to crack before.

.

.

earlier rev1

& 2 blocks supposed to be stronger between cylinder walls.

.

.

(although i think it a bit of a myth really).

.more of them seem to crack around the water pump area.

Rev 5 is generally stronger between cylinder walls

(although having it x-rayed is best to check if going for big power.

.

) and is also revised around the water pump area for this very problem.

.

failing that a 5sfe block is far stronger and will cope with pretty much anything you throw at it.

(but also the most expensive option)

Some serioud decisions to made by yourself now.
