right,
this is touted around so much on the internet, I'm not disputing/arguing/whatever that blocks do crack, because it's clear to see that people have cracked them, across all revisions, at all power levels, or that the casting was changed around the water pump area because that's plain to see
but
where, other than re-quoting anecdotal evidence from various forum posts, is there hard conclusive evidence that toyota actually changed the composition of the iron used in the blocks to increase the ductility of the material? because it's not your usual press release kind of stuff is it?
My point exactly, the internet can be an unhelpful friend as people with problems usual get heard the most.
Not to say there isn't a problem, but i think most cracking is down to detonation.
Even running a standard CT20b and ecu can cause detonation if boost is raised. Hense why we come back to how the car is tuned.
Any blocks cracked running standard boost?
