No problem, old threads never bothered me.

I tried valve seals, intake gaskets, PCV valve, compression & leak down tests, and probably others (this was in 04/05, so memory is a little shaky). Only when the exhaust valve quit sealing & we yanked the motor and disassembled was the broken oil ring found. My truck only had 80k on it when I bought it, and it had this issue then. It had a trailer brake controller, so it was probably worked pretty hard at some point, could be the cause of the failure. The valve stopped sealing at ~160k, but it didn't burn oil quite like yours..
