Which vvti engines are affected by oil consumption

[Ebob01]

Hi

I know this has been done to death but I can't seem to find a difinitive answer.

Does anybody know which vvti engines were affected by the high oil consumption? 

I thought it was mainly the old 99-02 1.8 but it seems people with 04 cars have had this problem as well, Corollas and avensis. 

I have an 08 avensis 1.8 vvti with 97k on it I've put 17k miles on it in the year I've owned and it doesn't lose a drop. 

Looking for a Corolla or avensis for my gf, I've read that since July 2005 the issue was solved but it seems to be all hearsay and folklore with conflicting information.

Also was this just a small batch of engines or was it more widespread?

Thanks in advance

1.4, 1.6 and 1.8 VVTi engines could suffer high oil consumption. 

I had a 2006 Corolla 1.4 VVTi and didn't have any issues.

True....and COULD being the operative word.

I had an 04 Celica and it didn't burn any oil at all...earlier ones (pre-facelift) certainly had a higher risk of doing so...but it wasn't a given.

Most VVTi engines like frequent oil changes and many oil burning issues were down to a poor oil change regime.

I changed mine every 5/k without fail.

So if you are buying a VVTi engined car it would be good to find out about the frequency of oil changes...if the regime is good then you should have little to worry about.

My current V6 Estima is a VVTi and gets the oil changed every 5k miles...never had an issue about oil burning.
