I am going to bring it in, jut to get it documented, just incase something happens after my warranty is up in 10k
wow! you sure are positive about your piston slap...lol. I think most GM I6, V8 owners notice some variation of piston slap soon after 10,000 miles according to what I've read. I know when I got my 2002 Envoy it had 64,000 miles on it. My 'Voy has had some pretty loud piston slap since I bought it and motivated me to add a block heater for the cold months! The block heater certainly cut back on the cold noises.I have it too, but with 114k miles it is to be expected, and I don't really care either. I think the sound gives it character.
I also have a 95 Eagle Talon, and that thing has had piston slap since I got it with 135k miles on it, now it's sitting at 205k miles and the Trailblazer is nowhere near as bad. If I managed to abuse the Talon for so long (redline frequently in 1st and 2nd gears) I believe that the Trailblazer will be just fine. I don't abuse the TB though, that is my new baby... Talon is just a fuel efficient toy, which still sees the red when I feel like being stupid.wow! you sure are positive about your piston slap...lol.
