you do set the top idler at  12 o'clock and the lower one at 3 o'clock not sure where you are getting confused mate but don't forget that is the starting positions, they will be in a different position when you have finished.

Hope that helps

confused beacause that what it says on dvd but how to says"Set top roller so arrow is at just before 9 o clock  & bottom roller at around 12 o clock (take up slack in belt)  and nip up E12 bolt securing with 30 mm ring spanner ring spanner"

thanks,looks like 12 and 3 it is then

The idlers are concentric (except lower one on the later 2.6/3.2 engines)

Basically, position them initially (whilst fitting belt) to the loosest position, which for most is 12 oclock for top, and 9 oclock for bottom.

Once its timed up, the top tends to end up around 3 oclock, and bottom around 12 oclock

 there see confused already,as dvd says fit a 12 and 3,not at 12 and 9 and then it will go to 12 and 3 :-? :-? ...or have i read that wrong as well..aaarrrggghh

Omega General Help / V6 cambelt change as seen on dvd

« on: 03 June 2011, 21:37:23 »

just bought the dvd on how to change cambelt on a v6,although not got an omega anymore,but got two gsi vectra's,so thought guide would come in handy...anyway watched dvd and confused,not hard to do ...when refitting and fitted the top and bottom rollers on dvd set them at 12 and 3 o'clock...now on the how to guides(see links below)i got for the v6 it says "set roller to 12o'clock then further down says "set roller to 9o'clock..also "tensioner pointer should line up in the centre of the segment" where as on dvd it should be on upper edge of guide....

finally got down to the garage today and had a look...took the top off and checked pipe work and noticed the pipe from servo to plenum got a hole in it...so got another piece of pipe to go on for now and hopefully will be problem solved....trouble is, car now in bits and someone wants to come look at it....typical...

Its possible the plenum hasnt reseated quite right, maybe one of the o-rings has jammed out of position allowing air to get in...as for the 4 pipes, the left hand of the middle 2 pipes runs to the furthest left of the 2 things they plug into...right to the one on the right...make sense?? I have a decent proper servo hose if you want one??

yeh makes sense...

sounds like you may have an air leak betwwen plenum and servo,check all the connections and that the pipe hasn't rubbed through where it passes the aircon pipe.Is the car running ok,idle speed correct etc?

the car running fine,and idling ok...what the four black pipes on top plenum as around there seems loud like it sucking air,and which way round do the two little ones go

assuimng you have removed and replaced the main vac pipe from plenum to brake servo.....maybe this wasnt fully sealed before, and now youve restored the vacuum?

which ones that the one that screws into side of plenum?

If the leak is from the cooler cover plate rather than the cooler itself then the colour of the coolant wont change.
I would clean the discolouration up, run the car for a while and then check again to try to ascertain where its leaking from.

can i just not do that from a pressure check to save putting it all back on only to take it off again

When you say the 'coolant' leak is clear, are you saying you only have clear water in the system with no coolant additive? :-/

yep near enough...had a little leak for a while but could never find it and when coolant check comes on just been topping it up with water..

it hard to tell where from the back,but the HBV been changed,but when went for mot and was on ramp,noticed where it had been leaking above starter as that was all rusty looking with coolant....was hoping by taking it all apart would be able to see the back...

would there not be a change in coolant colour if it was the oil cooler,as that still clear in reservoir,or can they just leak...the brown in between cooler and thermostat so really hard to tell till test done

got a coolant leak on my mv6,and decided to see where it coming from...looked,and as well as leaking at the back(from what i seen last time on ramps)noticed this,the brown is coolant,although only looks brown on photo,it clear in normal light...

so took top off for closer look and seen this

going to pressure test system on friday when get some bits from work,but does it look like the thermostat leaking,and running down front engine,or is that old looking,and could be running down back to the front...
hope it not cost to much as need to sell car so don't really want to be spending a fortune
