Was this from #7 cylinder by any chance?

Good insurance,

On any of the Gen 3 V-8's is to fit the pre 2001 LS1 steam tubes. As the left rear of the engine (5 & 7 cylinders) run hotter because of the coolant flow.

This thread talks about it but only fior the LS6 PCV conversion. The importance of retaining the steam tubes isn't mentioned.......

There's some pictures and better idea of it here on an LQ4 build:

Here's what happened with my #7 piston (which cracked the engine block).

Enough to convince me to go forged.
