Still going...

[Paul Bell]

2003 Ascander. Engine has only had LS6 PCV with a catch can added and a high flow/pressure oil pump.

3,000 mile oil changes with Wix XP filter and Mobil 1 Euro formula recently changed to Quaker State (I follow 540blog).

Engine runs strong, might not hurt to do valve springs and valve seals.

That would be 724,000km for the rest of the planet.
