Omega General Help / Matrix pipes little green clip pipe end

« on: 04 March 2023, 15:31:54 »

So, as part of my strip and check of the coolant and breather system on the elite (3.2) I decided to take off the matrix pipes and the coolant valve to check it all over.

I had a bit of a struggle figuring out how the pipes actually unclipped off, but then eventually got it. The top one came off quite easy, the bottom one was the proverbial bar steward.

Before I took the hose off, I could see a green plastic clip on the matrix pipe neck on both in and out pipe as in pic below.

although they weren't secured to the coolant pipe, just sitting on the pipe necks.

Once I had pipe off, I noticed that I could snap this green clip into the front of the pipe. Is that case, that you have to pull this green clip back towards you once pipe is back on? I don't see how that secures it though, or does it hold the clips on the pipe shut as well?

I think the HBV must have been replaced at some time as I can see some staining on the bottom of the pipe where the 3 pipes mould into 1 like it had been leaking in there at some point.

Not sure about those green clips though. With them floating on the pipe it would suggest this has been off before.

To finish off, here's what happens when you start putting your hands into the back of an omega engine bay, there will be blood!

General Car Chat / 2012 mundano oil and fuel filter change

« on: 06 February 2023, 13:52:20 »

Hi All

Got an oil and filter change to do on a mate's mondeo diesel and had a look at it the other day noticed you need a 27mm shallow socket to get the top of the oil filter cover off, the oil filter is a paper filter insert, and is situated on the front of the block, slighty to the left of the downpipe as you look at the front of the car, could get a 1/2" socket on it but not with ratchet on it as well. I think it needs to be 3/4" drive as it's a bit of a tight fit for a 1/2" ratchet.

Not had a look at the fuel filter yet, watched a video on the tube about this and it seems the filter is under the back near the tank, and you have to manually bleed the feed to the pump once you've changed it (There's no primer apparently - who designed that  ). However looking at his it looks like there is some sort of filter container thing on drivers side just under the big plastic cover on the engine.

Anyone know for certain if the filter is indeed at the back or can it be in the engine bay in these as well depending on year/model etc?

Thanks

Omega General Help / 2.6 metallic "clink" sound on start up

« on: 08 January 2023, 15:07:37 »

Hi

So car's been lying up over Winter with the occassionally start up and drive about to keep things from seizing up. I noticed today when I started it there was a sound that lasted for a minute or two then went away, what can only be described as a clinking metallic sound from around about the drive belt area. It was hard to pinpoint exactly the area it was coming from as by the time I noticed the sound and started investigating, it disappeared.

Hopefully this google video works on here if not let me know and will upload it to another sharing site.

nothing been done on car recently, last thing done was belt in 2021, and everything seems ok last time I was in there.

Omega General Help / Thermostats

« on: 07 November 2022, 07:24:36 »

Hi

Stat for v6 later model

Just wondering if anyone can recommend a good one, as there are lots of different makes. What one have you used before that seems to have lasted well etc. Couple of the one's I'm looking at are Mahle (Really expensive), gates/Febi mid-range price, then the usual other standard cheaper ones like Dayco/Quinton Halzell etc.

just going by price would probably go mid-range like Febi, but interested to hear everyones thoughts on makes or are they all much the same quality?

Cheers

Omega General Help / White Silicone grease

« on: 26 October 2022, 21:17:04 »

Been having a look through the workshop manual for various jobs like water pump and it says on installation to lube the mating surfaces and rubber seal with silicone grease (white). Is this not just vaseline or is it some other special gloop I need to use? I do like my lube

Omega Electrical and Audio Help / Removing diode pack screws

« on: 02 October 2022, 14:54:09 »

As part of my overhaul I'm double checking (replacing) the diode pack in the alternator with bosch replacement. I done this on my 2.6 and remember the screws were bar steward tight. On this one - the 3.2 - I got all bar one screw out. It's got colour marks on the screws blue on 2 and green on one, and a remanufactured sticker on it. Lord knows why they put those screws on so tight is it to stop schmucks like me tampering with it? 

Managed to get them moving with my snap on big handle screwdriver but will need a tighter fitting screw tip for this one as it seems a rather shallow depth screw, so the normal screwdriver tip is too easily working its way out the screw before much pressure is applied. tried flattening the head a bit with a punch to give the screwdriver more grip to no avail.

Anyone had similar issues with these screws for diode pack?

Omega General Help / Black sealant 90485251 equivalent

« on: 02 October 2022, 13:04:20 »

What is the recommended equivalent gloop to use for cam cover gaskets as it seems the 90485251 isn't available anywhere I've looked. Noticed in the guide it's grey sealant being used.

Omega Electrical and Audio Help / Auto selector inhibitor intermittent

« on: 01 October 2022, 20:34:42 »

Hi

02 2.6

Had this issue slowly developing over time and starting to get me thinking it's going to leave me stranded sooner rather than later and need to do something about it. I'm guessing it's the selector switch needing cleaned perhaps, but not sure. So what happens is you go to turn the key and nothing happens, if I'm in neutral, I have to jiggle the auto selector a little bit then it goes - while I have key in start position. You can hear there is an electrical / connection issue somewhere. Guessing the selector contacts are dried out and can be cleaned and regreased with switch grease or are they generally toast by this time?

Cheers

From what I was reading there is a green or a red colour coded one, with one being r134 compatible and the other...not? I'm not sure hopefully someone can enlighten me!

General Car Chat / VW Passat jamming seatbelt

« on: 31 August 2022, 07:32:43 »

Hi All

Just wondered if anyone has or had one of these cars, it's my brother's car (2014 plate) and the drivers seat belt is doing his head in, it keeps locking when he's trying to pull it on. He asked VW about a new seatbelt and they said they have them but are about 360 each just for the part, so problably 500 all in plus fitting.

I'm pretty sure this is one way i.e sealed unit and not able to fix. The VW garage said bring it in and they can check it, but imagine it's a new seat belt it would need.

Thanks

Omega General Help / CTS Number for 2.6/3.2

« on: 10 August 2022, 17:50:47 »

Hi

I know this has been asked probably a zillion times, but looking through the forum I'm seeing that the number recommended for the CTS is 90541937, however this number doesn't show up on the vauxhall parts catalog I'm looking in, if I filter on my VIN for either the 2.6 or 3.2 the number listed is: 90510493

Can't see that number anywhere in the forum. I've got a 90541937 here, a black one believing it would fit either engine. Just want to check if there is more to this or is that one ok after all?


Thanks

hi

Can anyone confirm the correct Elring gasket sealant I need for the oil cooler? I see on fleabay there is different coloured ones red/grey/black with all this technical mumbojumbo in the description, and not sure if there is a difference between them, if at all, or what one I need?

Thanks

Omega Electrical and Audio Help / Query about auto windows up with key

« on: 15 July 2022, 07:36:45 »

02 2.6 Omega (What else!)

Nothing major, just wondering why when I press the lock button in and hold that the windows don't go up as they used to do, even my old cavy does this, with the key held in lock though.

Only change to locks/key is a new key fob plastic bit, and the battery holder repaired by that guy on here.

Cheers
