      Timing Belt Problem 2006 Aveo ls

      2006 Aveo LS that i just bough
      Started car up was taking off and thump and car quit.

      Would not start well i knew what had happen so i
      remove top timing cover belt is still in place so i go
      on to removing bottom cover..

      Some +++ had replaced the belt and not the idler
      and it had froze up and belt slipped off, Removed
      valve cover and was able to put a screw driver
      between cam and lifter so i now have bent valves..
      Head not removed at this point.

      My question here is after looking a some u tube videos
      i saw photos of valves putting notches in the pistons
      if this happen do i have to replace them also?

      I just dealt with this, so hopefully I can offer a bit of help.

      Just bought a 04 LS sedan for my son's first car - got it for $500, knowing the timing belt had gone out. Pulled the head, and scored 16 for 16 on bent valves - in fact, the face of all the valves was flush with the head surface.

      The pistons do have a small relief notch in them from the factory, so you may be seeing that in some of the videos as well. A lot of it can depend on the conditions when it goes - a manual trans at highway speed is more likely to be catastrophic than an automatic just starting to rev up.

      I found one small nick in the #3 piston, that I was able to dress up with a jeweler's file - you want to make sure there are no sharp edges, and no major dings right at the outer edge of the piston circumference (above the ring grooves); as these will cause hot spots and premature piston failure.

      I replaced the following:
      - all 8 intake valves
      - all 8 exhaust valves
      - all 16 valve guides
      - head bolts
      - associated gaskets
      - tuneup bits

      when it was all said and done, car fired up instantly; all total, I probably have about 10 hours in it, including rebuilding the head and lapping the valves in.
