    Arent vz and vy the same body?? Why would the vy be lighter? Alloytech timing chain will stretch and get a rattle and eventually cause problems after about 100,000, ecos are way more reliable (Fact)

    No there really not, alloytech will last half the time of an eco, maybe the alloy are faster but the timing chain will stretch and stuff up quickly

    All im sayin is you shouldnt have to replace a timing chain after 100,000, ive had a vs and its done over 300,000 and havent replaced any seals, dose not leak a drop

    WM Statesman - VE SS Commodore
    Just sold an Alloytec WM with 260k kms on the clock. Only minor cold-start rattle, no leaks -no timing chain replacement anywhere in its history. Made my big-arse Statesman hustle in traffic. Smoother than any VN-VP or Ecotec V6 I've ever owned. The problems with the Alloytec are well documented, however. The torque curve isn't as flat as the previous V6s and doesn't come on as strong earlier in the rev range. The other issues relating to stretched timing chains and sludging come down to poor servicing generally and a sub-par PCV design, both easily rectified. Even the bad batch of chains only afflicted late '06 and '07 models. Not a perfect engine but to say they are crap shows you're ignorant.
