Were those the engines on the Aveo and Suzuki products that would constantly break timing belts or lose timing belt pulleys?

aveos are breaking timing belts even before the 60k mile interval. and they bend valves.

fair enough not all ecotecs are prone to the timing guide problem. i have one customer with a saturn wagon with an ecotec that has 360k miles on it. still going strong.

then again i had one that had 120k on it and the engine was dry as a fart externally but it burned oil. no indications of smoke or anything just locked up while they were driving. customer had oil changed every 3k miles.

Oh - I mean is the Vortec 1600 related to the S-Tech or D-Tech (whatever they called it) in the Aveos. The later Aveos did have an "ecotec" engine - but it was just the complete failure of S-Tech engine with an ecotec engine cove on it. It wasn't related to the Ecotec in the Cobalts or Sonics.

Both the Vortec 1600 and 2400 were actually based in older Opel designs, not related to the Ecotec or the S-Tec.

Aren't ALL the GM ecotec engines originally from Opel? All the current ones seem to have been developed by Opel before coming to USA, for example, the 1.4L engines (NA & turbo) in the Cruze, Sonic, Spark...and Volt.

Yes. But the Vortec 1600 and 2400 are based on its predecessor.
