Duncan Posted May 4, 2015 Report Share Posted May 4, 2015 hello, does anyone know what year(s) of manufacture was affected by the oil consumption/piston ring problem with this engine? Is there a particular engine number identification to look out for? Thanks Quote Link to comment Share on other sites More sharing options...
Hiro Protagonist Posted May 4, 2015 Report Share Posted May 4, 2015 From memory the issue only really affected the non-VVTi 1ZZFEs fitted to the ZZE112 Corollas in North America (Australian and Japanese models soldiered on with the A-series motors). If you're buying an Australian-delivered 1ZZ then it will be the VVTi model and shouldn't suffer the problems that the US ones did. Quote Link to comment Share on other sites More sharing options...
Duncan Posted May 5, 2015 Author Report Share Posted May 5, 2015 thankyou for your reply Hiro. Now I'm confused, I thought that 1ZZFE engines were all VVTI's ? I have a 7A engine in my 1998 rolla. Obviously not the same thing. Perhaps I am incorrect but I am sure that I have read about aussie owned 1ZZFE engines. The one that I am looking at is a 2004 model corolla wagon.

Hiro Protagonist Posted May 5, 2015 Report Share Posted May 5, 2015 All Australian-delivered 1ZZs are VVTi. North America got the ZZ engine a series earlier than Japan and Australia did (in the ZZE112 series, whereas Australia had the 7A-powered AE112). I've mainly heard about the horror stories in the US non-VVTi models, not to say that the later ones sold here are immune but it definitely seems less common.
