Omega General Help / Re: How do I remove the oil filter body on a paper element filter?

« on: 15 August 2013, 20:06:43 »

Thanks for all the help, chaps. I tried to photograph the centre of the tube, but it was hard to get illumination inside the tube. I am not clear how I could smash it off, access is so awkward.

I still reckon I need a long T60 Torx male tool. I could not get one today in Midsomer Norton, but Machine Mart in Bristol claim they have one. I shall buy it tomorrow and try it Saturday.

All this fuss just to change an exhaust manifold! I wondered if I could saw through the transfer pipe and replace it with a hose, but even that does not look easy. Has anyone tried that?

There are 2 fittings, 12mm hex and the other I believe is a torx

Thanks. That makes sense. I reckon it's a T60. Trouble is, I need a long one to b get down the tube in the filter holder. I had the same problem with the hexagons. A 12mm hexagon in a 1/2" socket would not go in.
I rand Bellinger Grove, main Vx dealer, but no-one there knew. They think they have done it, but not recently, and could not remember what tool they used. Probably about half an inch, they said. Or 12mm.

Is there any correlation between Torx sizes and hexagon sizes? 12m and T60  sound related.

It could not be a Torx, could it?

Gentlemen, I thank you all for your help.I rushed out to Halfords and bought a 12mm hex socket, but the 1/2" body was too fat to go into the tunnel. I then found a set of long hexagons I bought years ago for Senator driveshafts, tried the 12 from that, and it would not go in. Tried the 10 and it went all the way in and did not engage. Could it be an 11? I ground the 12 down to about 11, and it engaged, but felt weak so I did not apply torque. Tomorrow I shall try to buy an 11mm long hexagon. Funny everyone is saying 12mm though. . .

Thank you gentlemen. My problem now is how to engage the hollow bolt. I have tried all my Allen section tools and they all seem too small. I have tried some long bolts with hexagon heads and they seem too big. I have not managed to see inside the bolt and confirm the hole is hexagonal. I am looking for more long bolts. If it is splined I am dead unless I can obtain the right tool.

I have got the filter cap off with the filter. However, the body of the filter holder is still in place, and this obstructs my undoing the oil pipes. Having read the 'how to switch filters' I imagined the paper filter holder body should unscrew like a cartridge  filter. However, using a strap wrench, I failed to turn it Thanks, Andy663. I gather you have managed it with a rubber strap. I see indentations in the filter holder suggesting there may be a special tool to unscrew it. Andy suggests that if I can get hold of it it should unscrew like a cartridge filter. Please confirm this is right.

I am striving to change the RH exhaust manifold, following RobG and Haynes. I have to remove the oil pipes at the filter end. I have removed the paper filter, but the filter outer is still in the way. I feel it should unscrew, but it does not want to. How do I shift it?

Omega General Help / Re: cracked manifold.?

« on: 11 August 2013, 20:41:18 »

I doubt it. I have had three 2.0 Omegas with cracks exhaust manifolds (on top, under the heat shield) and while the spotting noise at idle was annoying there was no obvious decline in performance.

I currently have a 2.5 Omega with a cracked RH exhaust manifold. The crack occurred suddenly two years resulting in a spitting noise idling cold, but diminishing when hot. It has got worse, growling all the time. I have now obtained a second hand manifold and shall change it when I can find the courage. The performance has not changed a bit.

The 2.5 issue is probably just the gasket failed. My old 2.5 did the same.

I hope you are right, but I doubt it. It happened so suddenly. I suppose a stud could have broken.

Hmmm, that's not so normal. Usually, it sounds a bit futty on start up, which disapears as it warms up. The worse it gets, the longer it takes for the noise to subside. Until eventually, it never stops and constantly blows.

You have described exactly what has happened over 2 years. I have had several 2 litres suffer manifold cracks and behave this way. I assumed the 2.5 had gone the same way. I will let you know when I strip it.

Omega General Help / Re: Do V6 aux belt tensioners vary?

« on: 05 August 2013, 22:26:38 »

covers are different mate-only mm's I know-had same problem

Thank you. So would the aux belt tensioner off the 3 litre have  fitted with the 3 litre cam belt cover, or are the threads in a different place on the 3 litre? I think I kept the tensioner off the 3 litre too, but it never occurred to me that they might vary.

There's a bracket on the same bolts. Could that be interfering with the fit?

The bracket on the lower bolt for the wiring harness guide was no trouble. It seemed as if the new belt cover was too far forward to allow the bolts to engage in the threads. I put back the old cover, bolts went straight in. Covers looked both the same.

X84GNB 2000 2.5 manual petrol estate
On changing my cam belt I had planned to replace the cracked cam belt cover with a spare I took off a scrapped 1999 3 litre. It fitted all right, but I could not get the auxiliary belt tensioner on. I replace the original cracked cam belt cover and the tensioner went on The cam belt covers looked the same. This puzzled me.

This morning I wonder, would the tensioner off the 3 litre have fitted? Do they differ?

Omega General Help / tensioning cam belt on a V6

X84GNB petrol 2.5 estate
Mr. Haynes says I should set the index mark on the tensioner plate 3-4mm above the mark on the backplate stop (with a picture). Mr. SKF. maker of the cam belt kit, tells me to align the two markers. I do what I am told. My instinct, given two lines, is to align them. It's probably unimportant. What to you guys do?

Remove inlet manifold.
Unclip & remove rear coolant hosework
Remove expansion tank.
Remove airfilter box
Remove transfer pipe
Remove heatshields and disconnect front downpipe
Remove ex. manifold.

Thanks Rob. Beautifully succinct. Now I can face the job. Haynes frightened me.

The car is almost due for a cam belt change. It is tempting to do it at the same time. Is there any reason why this is a bad idea?
