Timing chain, sprockets, & cam position sensor problems?

[PetersRedYaris]

Question? Doesn't the Yaris (US model) use the same engine as the Echo, XA, and XB? Are there any differences? I've seen these cars go 250,000 miles without problems. Why might the Yaris have timing chain problems?

I've not been able to find any noticable differences between the Echo and Yaris in the Engine itself or the valvetrain of the engine ... I don't know why the Yaris would be having these problems, unless it's just isolated incidents among a handful of cars, all of which should be covered under warranty.

the laws of mass production indicate there will be some lemons :)

is there a recall you need to share with us, what timing chain issue are you referring to

I also was thinking it was just a few isolated incidents. Strange, however, they both occured in Canada.

Hope its just a isolated thing the guys with the problems should post the date there cars were built.I talked to my toyota tech before I got mine he said they hadn't had any engine problems with the scions.when talked to him i was also thinking about a corolla he said they were having oil ring problems with some of the new ones mostly with people that drove short trips a lot not people that drove mostly long trips
