Read the original post again for Christs sake. It says listen out for the tinkle (and then rattle) of a failing timing chain tensioner and get it sorted before it snaps. It costs £5-800 to sort it, which is cheaper than another engine.
So your original article talks about oil starvation in the 2.2 Vectra engine (circa 2002?)
leading to timing chains going.
What has this got to do with a dodgy batch of timing chains in the 2.2
in 159s and Breras?
Who are these "many mechanics" you've spoken to about these issues?
How many mechanics is "many"?
Could you give us some refs so we can check it out?
Look, it's obvious you've posted this to help people out in the good ol' fashioned AO way,
but reading your post it seems like you're suggesting that all of us 2.2 owners
have been saddled with dogs because they have Vauxhall Vectra engines in them.
Just want to clarify how something that was supposedly fixed with a GM recall is
now affecting our cars 6 years later.
