What episode is Itachi vs Orochimaru?

no one really knows what episode obito dies in all we know is when he dies he stabs his own eye when it has sharningan and slashes kakashis eye with that kunie giving kakashi sharningan

actually he died when he was saving kakashi from the rock slide in chapter 243

Actually, There is an episode in the anime. It's Naruto Shippuudent episode 119 & 120. It's a flashback episode for Kakashi.

*Spoiler Alert!*

It also shows Naruto's Father, Yellowflash or fourth Hokage, And his teammates. It's how he came to care for his teammates and how he got the shirigan(SP?)
