My 05 LGT has it's 3rd short block in it, had two cracked pistons when I bought it so the dealer had to fix that. The bank made me put some bs aftermarket warranty on it so before it went out I took it back to the dealer that sold it to me, rings were "bad" so I built it, finally added the last piece and the final tune and hit a deer so I'm looking for a silver hood! Not too bad but not something I'm gonna drive around like that. I haven't heard valves going, plenty of ringland and piston issues though.
