Hi Guys

Just got back from local Vx dealer with oild filter and airfilter. My problem is the oil filter looks wrong to me dose anyone know the GM part number of the correct oil filter for an 'X' plated 2.6 V6.

I just want to check before I drain the life blood out of the beast???

oil filter on 2.6 should be a paper element type, not spin on traditional type (unless somebody has modified your car)

[V6CDBOY]

Ok I stand corrected thats what they've given me How the hell do you change them!!!! I've only changed a metal screw on one before.

I have a 3.0 V6 and i believe they are the same filters, it should be a paper cartridge not a tin screw on filter, beware tho the first i had was for a Vectra, very similar but the centre hole was narrower and did not fit the omega.
The part number on the box from Vauxhall for the one i fitted was 9192426.  It comes with a new rubber O ring.

Changing is pretty easy, first drain the oil as usual, jack up and support the front, you will see the housing on the n/s of the engine behind the n/s/wheel area above the steering idle arm, the crank sensor is fitted next to the filter.
The housing is an alloy housing with an end cap and in the centre is a 3/8 socket.  using a normal 3/8 socket wrench straight into the cap I managed to unscrew it, be ready for oil to come flooding out.  there is a drain on the underside of the housing where you can drain the oil first if you wish.
Remove the cap and the filter can be slid out.
Refitting is the reverse but make sure that the filter seats into the cap properly so as the plasic clips hold it in the correct position. 
I found it easier than the old tin types to replace as you dont get the splitting of the tin can if it is stuck firm.
Hope you get on ok with it buddy.

Thanks for your help, I'll try it later if the rains stops!!!

One final question while I think of it. A lot of people talk about torque settings? Can you still do this job without a torque wrench?

[hubbardybubbardy]

Yes you can is the answer, I did, just be mindfull not to over tighten,  use a smear of clean oil on the new rubber O ring fitted to the cap and this allow it to fit without tearing with friction or being displaced when screwing back into place.  As for how tight, just resonable pressure on the wrench will do, dont put your back into it tho !!! you could crack the cap or housing and that would be trouble.

[hubbardybubbardy]

Oh and if you have a 24mm socket you can use this to remove the end cap from the housing, some prefer to use this over the 3/8 wrench, either do the job its just easier access with the wrench so long as the cap isnt siezed on. All the best with it...

Don't overtighten it when replacing! Many folks on here have found that monkey mechanics have done so, resulting in stripped threads and an unnecessarily major job to get at the filter, and the need to replace the whole casing.

Hi guys

Ok this oil canister cap is really tightly screwed on should I leave it and get done by a professional?

Hi guys

It's probably been done by a "professional" in the past, that's why it's so tight.
For professional read muppet with a windy gun.
Ended up using a chain wrench round the housing and 3 foot of scaff bar on the socket bar to undo mine the first time.
Surprisingly when done to the recommended torque figure they undo no problems.

Spray some releasing oil on the cap where it seats on the housing, use a 24mm socket for the extra leverage and it should move, remember even the old style tin filters are sometimes stuck solid when trying to remove but they do eventually turn.  Just one thing, check you are turning the right way to loosen as when your upside down on your back underneath it can be dissorientating and you could be tightening by mistake.   

[V6CDBOY]

Good thinking!!

I' turning the oposite way to the direction of the 15Nm arrow so I think I'm right in otherwords anticlockwise?

 

[hubbardybubbardy]

Captainzok is right, sometimes the prof garage can really overtighten the cap just like tin filters, they just dont want it back with a leak from not tighening enough!!! and they also get you back to remove it if its too tight for you.  It will turn with patience dont worry, bitof WD40 may just do the trick or other release oil.
