ok thanks for the help guys, il try and get a new 1 fitted, see if that helps me!!

1.0 12v timing chains are commonly noisy. I have replaced 2 at our garage. You cant adjust them but have to buy a new chain and tensioner. Think its a hydraulic tensioner.

ok ^^^ simon says .....so it must be :D

The interval for the chain is definitely 100k.

i will get the timing chain replacedwhen i get home, right now im on holiday in the uk :)

My 12v makes all sorts of noises under the bonnet :lol:

Timing chains usually rattle when they are on their way out. They are meant to be a non serviceable item but if you drive it hard then they do start rattling

You could record the noise and post it on here, to give people an idea what the noise sounds like.

Could be the timing chain then.

mine is just over the 78k mark now, its like a whoosing noise, my mate has built engines before now just about, and he thinks its the timing chain....

Firstly, Help Zone.

Secondly. Mine doesn't do that, and it's on 68k. Go pass 3.5k/4k rpm and it makes a high pitched noise though, like a turbo :lol: this is normal iirc.

I doubt it'll be the timing chain to be honest - it is generally supposed to last the liftime of the vehicle! How many miles has yours done?

ok, here goes, i have a 1.0 12v corsa B, and over 3k revs, she makes a hissing noise, my friend who is knowledgeable on all things vaux says its the timing chain making the noise, or at least summat on that side of the block. is it possible to tighten the chain? or does it have to be replaced??
