Oh, i heard too this problem with a Vspec. I didn't have such problem and i think i push enough my engine plus that when i was COMPLETELY noob, it was running at SUPER lean at high rpms most of the time, replace a cylinder, piston, con rod, and it still going. One guy in offroad forum had the Vspec and he was racing, and he complain with the bearings, of course he order new ones but not from OS since it would be the same thing he said. Now he bought a RB, of course that's just offroad.
