IS 20 Revision Question..

I've read that on GTI's there were issues with these failing.. Do those same issues exist on our engines? Looking at a "G" revision for sale and was wondering if I'm safe or should I look for a later version..

If it matters I would be using this on an Alltrack with a JB4..

It's the 702 revisions that had problems, which ended with the T. Pretty much anything 722G and later is good (or at least much better).
