If the block is prone to failure I'd rather avoid it all together. But my main question is if Cosworth uses OE EJ25 cases... why haven't I heard of any of them failing but other OE cases fail?
Weird... I'm going to call Cosworth and ask today
Who have you talked to who is running a 704 series Cosworth long block? You have to take into consideration the sample size. Fewer Cosworth blocks are flying off the shelf therefore there is a smaller sample size for comparison therefore you will hear less about the Cosworth failures if any.
This is a rather new problem also. If it is legit in time you will see more instances of it but being that is is a relatively new problem you shouldn't expect all of the block to fail at once and everyone to instantly post their failures on Nasioc. Give it time.
