Whining noise?

ramondo

Hi all, I've already introduced myself on the newbie section. :thumbup:

A few months ago I got myself a Vectra hatch 2.2 SRi. I used to have a '98 - 2 litre, which I'd owned from one year old, but someone decided to drive into me and write it off. :sick: It had only done 62000 miles and was in perfect nick.

Anyway I found this nice black 2.2 on the adtrader website. One owner, full service history and 66000 miles. 51 reg, Jan. 02. I've sorted a few niggly problems but there's one left to do. This is where I need the advice from you guys.

I've got this whining/droning noise which is most noticable at low speed and tickover. It seems to deepen when ticking over at around 700 rpm. It seems to be coming from the timing chain cover area. I was hoping it was something simple like the alternator but I don't think it is. Do you guys think it's the water pump or the chain itself?
I haven't checked it out yet, but I would think it's the original chain.

There's one other thing: if I change gear below 3000 revs the engine speed seems to rise a bit (when de-clutching) before falling. Is this normal? can I get it cured by Vauxhall altering the ecu? Thanks in anticipation guys. 🙂

the engine speed hanging is quite normal, thats the electronic throttle.

I would advise you get the timing chain replaced as they can suffer from brittle guides after many years.

the noise could be the water pump, the auxilary drive belt or belt tensioner

best to get a second opinion just in case it's the timing chain

I had the same noise from my Vectra, had the tensioner changed first but it turned out to be the Pump in the end.

I would definately get the chain looked at ..... it`s a bugger if it goes cryb.. :oops:

Thanks guys for the replies so far. Will be changing the cam chain, within the next few weeks, and will let you know the outcome.

Drakey

Good news, hope it solves your noise, and yes, let us know ho you get on.

I've now got my cam chain kit and will soon be starting the job of fitting it. I've had a look at the parts in the kit and I've got a query with the oil nozzle. How big are the two oil outlet holes supposed to be? These are about 1mm.

That sounds right mate that confused me to whats the point in modify it if it still has the same chance of blocking up??

ramondo

Yes that's what I thought. They've took out the brass bit from the input side to give it a bigger hole but the outlets are the same, so you could get a blockage there.
Maybe if the outlet holes are bigger though it wont spray out with any force?

blue_se2

Yeah you would lose pressure with bigger holes.

I still stand by my usual advice SERVICE REGULARLY!!!!
