Bought a small mixed box of them from toolstation for 2.17  Product code: 53005 Pack size: 85 Piece. There was a size that fitted, so all sorted.

It is the 2 small o rings in the fitting where the gearbox cooler pipes come over the top of the rad, to the rad in the middle. The ones I meant are circled, the parts dept. bloke at local vauxhall called it a banjo. He said the 2 O rings are no longer available. It is a 2.6ltr

fitted new rad, but the O rings in the gearbox pipes to rad banjo have had it. Does anyone know the dimensions for them, or where I can get them from, need it sorted by Friday at the latest as moving from Scotland to Darlington?


Thank you. I have probably missed it for the torque. Is the O ring reuseable.

Can anybody tell me the torque for the gearbox pipe banjo to radiator on a 02 2.6? Also can the same O ring be used? Last question can the bagpipes including vac tank come out as one, once the two black vac pipes that goto back of engine are undone?

I haven't removed locking tool so they are still in position as in the first set of pics I put up, showing cam sprockets and camlobe positions.

Do I remove camlock before setting pointer over to right, or after it? also Will the tension be slightly hard when adjusting over to the right? Sorry for questions just want to make sure I have directions right before I do something.

pictures showing pump in place and how tensioner is set, ready for belt to go on, I moved the allen key part slightly and the belt is on.I haven't moved the key to move the pointer over to right hand side yet, ready for first 2 rotations of crank. Is the allen key part correct at 7oclock for fitting belt, and 5oclock when set correct?

Crank is at TDC, as I made at note of where it was for removing and replacing head and cams and how much to bring it back upto TDC.

I fitted the tensioner, and read on Gates site that it should be set to 7 oclock on the allen key part, with pointer over to stop on left, before fitting the belt, otherwise it can cause problems when the engine is running once tensioned is that correct? Read the how to in maintenance for head gasket and belt change, it just says set the tensioner adjustment to the minimum (fully anti clockwise). Locate the teeth of the cambelt into the crank sprocket etc.

How did you find out about the pump?

Here is what contitech say for that kit:-

In vehicles it says opel omega x20xev.

The lug of waterpump is inline with the lug on engine, roughly 11oclock. Allen key part is 7oclock

Can anyone tell me why the Contitech timing belt CT870, which came in the full Contitech kit CT870K1, will not fit on my Omega 2ltr, the kit is the right one for my model car. It is as if it is too small, the tensioner is set as it should be, Allen key piece at 7oclock pointer by waterpump. If I pull the right side as looking at front of engine tight, it seems as if the belt sits on the peaks on the cam but they are timed correct. If I fit it as per instructions clockwise, it will not go on, as too tight. It is driving me mad.

Set the Timing marks up on the cams and locked them. Both No1 EXHAUST AND INLET Lobes look like this, almost level. (EXHAUST are the first two closest to you, inlet are in background)

Do they look OK?

Thanks for the quick replies.  No I didn't fill the lifters as I read it can cause them to lock solid, so let them fill naturally. Did lube them before fitting into head.

I did turn crank off TDC to prevent valves hitting pistons.

I do have the locking tool for the cams. I did not remove cogs as could not find the timing mark that is supposed to be on the first bearing carrier, so thought safer to leave them on. Have checked the seals and they are seated fully home.

Doctor Gollum,  how can you tell if out 180?

I am refitting the exhaust and inlet cams, Haynes manual says make sure No1 cylinder lobe is up, when I do that timing marks will be out The writeup off this Site for Headgasket replacement says put them at TDC, I cannot get them to stay at TDC. I never removed cam sprockets so they are correct. Also removed cams one at a time, along with carriers, and wrapped in seperate marked boxes, so not wrong way round. Here is a pic of exhaust Timing mark position now against rocker cover. Could it have something to do with me cleaning out the lifters, they do compress and spring, they also went back into the places they came from. Can anyone see anything I have missed or should it do this? Thanks for any help, it's driving me mad  :'(
