Hi guys,
Ok, well got home from school today and checked over the timing belt. There's no missing teeth and belt looks good except for the following things:
This is the part of the belt that looks fine and has rubber all round...

This is the part where the red chord seems to be coming through...
(http://i1226.photobucket.com/albums/ee402/webbybear1/cs2_zpsfb8e6ba8.jpg) (http://s1226.photobucket.com/user/webbybear1/media/cs2_zpsfb8e6ba8.jpg.html)
Is this normal?
I looked on my old belt and that has exactly the same (some bits showing red cord, some not) but that belt was 4 years old when removed.
Finally re the squeaking..... I note that some of the lettering on the belt saying ''CONTITECH'' is still there and some disappearing from wear.
So really my questions are these:
1.) is that chord coming through normal?
2.) we reckon this squealing is the paint?
3.) can I drive it?
Cheers boys :y

If the belt was rubbing you would have rubber dust and debris present,also where the belt had rubbed would be quite shiney as would whatever it had been rubbing against,can't see from your pics if it is rubbing or not ???
-
Thanks Henryd.
Belt looks absolutely fine apart from the chord showing. :)

And no fresh rubber dust or debris?,chords in belts are often visible at the side so shouldn't be an issue
still doesn't explain your squeak though ::)
-
Sorry not been following this, what squeeking? Is it present when rotating crank by hand?

I'm going to be honest that's difficult to say. When the cambelt shredded in August it decided to leave an explosion of debris everywhere. I of course cleaned most of it up but there was sooo much that inevitably I didn't get it all.
this time though I've cleaned everything (not the belt or pulleys obviously) with brake cleaner and removed as much debris as possible. only real place there was build up was the water pump and a pool of crap under the crank pulley but I think that was from last time as i specifically remember only being concerned about the pulleys themselves.

timing belt squeaking mate. verified by me removing the aux belt and running car. I stripped it right down and only areas of concern I noticed were the grease from the pullies (which we now know is nowt to worry about) and this cord showing.
the only other possible explanation is I have heard the paint for the lettering on the belt is thick and thus will squeak til it wears down. but obviously even if that is the case its still disconcerting :'(
-
oh and no its not present when rotating by hand :y
-
Humm, does sound like tensioner. Do you have locking kit? Take tensioner off and spin by hand? On one of cambelt changes on my 2.2 resulted in a dud tensioner, within few k it was squeaking badly.
-
Red cord is normal. From looking at construction I'm guessing belts are made from big tubes cut in to sections with the red cord running continuously wound throughout its length.
It then follows that there must be a section where the chord is cut through to make the individual belts.
Slight squealing is common where liquids such as oils or coolant get on the belt during fitting. It will stop squeaking/squealing once the residue wears off.
Assuming its just residue on the belt, yes drive it. (But then I haven't heard the noise in question, so up to you ultimately ;) )
-
Start engine w/o timing belt cover and use stethoscope w/o stick to listen all pullies
-
Mine has been doing this for about two yrs. the squeak seem to be one squeak every revolution of engine it stops when I drive off and doesn't come back again till next morning and its worse in the winter. Got into the car the other day, engine missing all over the place. Sounded like a tractor. I have a new diss pack to fit when I have done that I will have to look at the belt. not sure whether the noise and the misfire are related or not yet. I will post and let you folks know what happens.

Should have said 'every revolution of the cam belt'
-
Good idea car5car but without the bagpipes the car doesn't run as fast as normal and thus the squeaking is not there.
Re the tensioner..... when we fit the cambelt me and Jaime put the new tensioner mark on the upper edge (like in the video). yesterday, when I put the car to TDC so I could fit the crank pulley correctly, I noticed that the notch was bang on the little cut out line..... car has only done 40 or so miles since we set the tension.... should this have moved down already to the line or should it still be on the upper edge? :-\
-
oh and just to add.. it only appears to do this at idle. stick some revs on and it goes. :y

defo keep us updated mate :y

It's normal for the belt to bed in and the tensioner should find its' way to the centre line. This is why it's tensioned a little tighter than that when fitting a new belt.
If it was tensioned correctly at fitting (and with TB's guidance it would have been), then I wouldn't worry about it. TBH, if the debris is cleaned out, and there's no sign of it rubbing anywhere, it's nothing to worry about. I would put it all together, making sure the cover is aligned so that the belt doesn't rub on it, and see how it goes. Chances are it'll disappear as it all beds in.

Thanks Kev.
Just to highlight (in case anyone wonders) TB set up my belt PERFECTLY! The car runs soooo sweet so i hope i didnt give the impression it was anything TB had done. i'm very much in debt to TB and Martin for their help :y :y :y
As far as the squealing goes... i'm not going to worry about it. At the end of the day the worst case scenario is it gives up and i end up doing it all again. Well at least i have some heads i can refurb and i now know what i need to do :y
Obviously i'm hoping that doesnt happen ::) ;D but if it did it wouldnt be the end of the world.
Thanks to everyone for their advice :y
Ps, if the sound persists like over a month or so i may replace idlers and tensioner just for piece of mind... see if that works. Can you buy them seperately? :-\
:y

Definitely the diss pack Got it out and split all over the place. Got the new one back but now have lost a pipe from the back of the plenum one of the middle ones. don't know if anyone knows where they originate from. The squeak I will investigate further when the car is back together.

Do you mean one of the breather pipes?

Just to add....
parked up at school today and it was running sweet at idle - no squealing. then went to car park later on to show a mate the Omega (he was reminiscing about his dad's omega years ago) and it had been sitting for a few hours so was stone cold. it started the squeaking. he got in and started listening and it seems its coming from the tensioner area...or at least that's where it was loudest :y
he pointed it out and didn't know where the tensioner/idler assembly was.

There are 4 pipes coming out of the black contraption on top of the plenum. I have three. One is missing I really wanted to know where they originate from so I know roughly where to look. probably dropped down the back some where.

Is your squeak constant or every rev of the belt.

Two outer pipes become one and go to the large inlet on the breatherbox at the back of the 135 head, similar position to dispack but tother side...
Smaller middle pipe goes to the small pipe on the breather box.
Fourth pipe goes to the Purge Valve from the carbon canister in the righthand wheel arch. Sits between breather box and HBV :y

Well, drove the car for over 50 miles today. I started it up after an hour cold and it didn't do it. Hopefully it's bedding in and it will gradually go away. I'll keep my eye on it :y
If in a months' time its still doing it and just for piece of mind I feel like replacing idlers and tensioners... would Vauxhall sell me them separately? :)

Got that thanks mate.
