4,324TT 310SMOH 225 since new Millenium cylinders.
Confusing here...If the engine has 310 SMOH,
why would it have 225 since the TOP. To me, not proclaiming to be an engine guru but fully understanding the mechanicals of it, it seems like that issue would've been addressed at the time of overhaul while the cylinders were
off? 
Maybe some of the members can enlighten me on why this would've been overlooked?
