Omega General Help / A bit of an odd brake problem.

« on: 24 February 2011, 02:49:42 »

Yet again my Omega continues to amaze with me it's spectacular ways in which to break and fail. Todays failure is no different. 

Having replaced all the discs, pads and handbrake shoes, yesterday was the first time that I had driven the car for any distance, (or at least I did before it developed a missfire).

Anyway, above 10mph or so I noticed a rattle coming from the near-side rear corner. It sounded like a tick-tick-tick-tick-tick-tick, that got faster the quicker I drove. When I came to a stop, the ticking stopped also.

I assumed that one of the dam retaining pins / springs / caps had fallen off the handbrake shoe, and it was this that was rattling around inside the 'drum' part of the rear disc.

So, wheel off, caliper off and disc off and all seemed fine, much to my suprise, untill I noticed that it was dripping brake fluid. The problem is pictured below;



Even though I thought that the brake line was well clear of the suspension arm it seems that it has been rubbing against it, and over the space of 25-30 miles it has worn right through it.

Yeah! more expense 

is this some sort of common Omega design fault? Or should I be ensuring that the brake lines aren't just clear of other componants, but very, very, very well clear?

I am based in Norton Canes nr. Cannock,Staffs. WS11 9TP.

Not quite local enough for me, but I picked up one from eBay for £56 inc delivery.

I'd be willing to rent mine out if your interested?

Thanks for the help, if it is the coil pack how much am I looking at and can I replace it myself ?

From Vauxhall they are silly money, but I believe that they can be bought from Bosch (or Bosch stockists) directly for a lot less.

The job is pretty straight forward for a novice, (erm, that's me as well). The only 'specialist' tools that you will need is a selection of female Torx sockets, a male Torx socket for the dis-pac bolts, (T40 or T45 IIRC?) and a decent low-reading torque wrench. Halfords do a good 3/8th's drive one for £69 that is calibrated to +/- 1%.

The hardest part of the job is likely to be getting the old dis-pacs out, as there is a certain knack to it.

If you have a look in the maintinance section then there is a thread on how to remove them.

if you want to know how good / bad a novice found doing that job, (erm, me again), then have a read of a thread entitled "Getting her back to tip-top" in the Omega Gallery section of this website.

Good luck

Ah, sounds like out Omegas share the same problem, (although it's number 6 that I have the missfire on).

Have a read of this thread and it should be giving you plenty to get your teeth stuck into;

A couple of quick questions for you. When were the cam covers last changed?
Are you loosing any coolant?
Do the fans still blow nice and hot?
When were the spark plugs last changed?

If you do change the plugs yourself then they all are dead easy. You will need a u/j to get no;6 out though, and the plugs may have been put in 'dry' (no lubricant), so they do make some un-nerving noises when coming out. Be gentle but firm and you should be alright. Also dont put them back in 'dry', use a little copperslip on the spark plug threads.

I also wanted to add that during the vehicle being valeted, the engine wasn't steam cleaned.

Ok, had the plenum and passanger side dis-pac off tonight. Everything seems to be in order? No swimming pools in the spark plug wells. No wet or damp around the spark plug shrouds. Plugs 4 & 6 both fine, dry and free from any signs of rust. Even the dis-pac edging and no;6 spark plug shroud aren't as badly damaged as I remember them being. Pics below;

plugs 4 & 6. no; 4 is on the left in both pictures.




edging around dis-pac not too badly damaged, (although I cant remember the bolts being so rusty?)



spark plug wells dry. although I couldn't find the rubber 'O' ring in pot 6?

pot 4; (on left)


pot 6;


And the dis-pac & shrouds. I couldn't un-plug the dis-pac for a clearer picture. Sorry.

The damaged shroud (pot 6) is the one on the far right.



The scuttle drain (passenger side), is clear. Pollen filter dry, but the rubber that runs along the top edge of the bulkhead, although in position, can easily be pulled off.


Any further suggestions please chaps?

Thanks

Does the little red light on the fob light up when you press the lock/unlock buttons?? If not and you have a new battery then the most likely situation is that the battery holder in the fob has snapped...easy enough to weld but you will often find its just held in place by a piece of folded paper...which of course can shift...

As the misfire is on no 6 which is the one with the knackered lead I would say change the lead, clean up the plug and see if that gets rid of the misfire...

If you can head over here I can stick the computer on it and reset old codes etc...

As for the chip/immobiliser, if you can start the car then the code is old...if it was current then it just wouldnt work!

Thanks for the offer. i may take you up on it 


The keyfob remains in-op as it was only the car battery that was changed.

Mines the later 2.6, so no leads as such, but the sleeve / shroud for pot 6 is quite damaged, and that (I think) is likely the root of the problem. Just looking after the little 'un (and trying to work) whilst the wife has nipped out for a couple of hours. After which I'll have the coil packs out.

If I was to run a bead ofsilicone sealant around the edge of the dis-pac, (where it got damaged removing it), I assume that that would be sufficient to keep it water tight? Would the silicone sealant cause any problems with the heat soak it will suffer?

[/highlight]




No I don't think it would cause any problem & may cure any spark tracking temporarily allowing the plug to fire correctly, but the probable cause of water ingress to No.6 plug is a leaking scuttle joint imho & you should check the soundproofing material under the scuttle to see if it is/ has been, wet. You can fix this by running a good bead of silicone down the joints & seal around the holes for the wiper shafts.

I reckon that you are on to something here.

After having it valeted the inside of the car kept on steaming up every ten minutes or so, even though the interior mats had been fully dried. And yes, I have already cleared out both of my scuttle drains.

Did you say you had it valeted?, if so did they jet wash under the bonnet? if so they could have gone mentle and filled every nock and cranny with water.  Misfire could be the dis pack has failed due to water ingress.check the leads and replace if you suspect them, as they do not age well and together with a poss dousing with water could be the cause.

I've yet to open the bonnet on it, (been a very busy day), but I don't think that a steam clean of the engine is part of the £15 valet that I had done. I cant be 100% sure though untill I open the bonnet as I left the car with them whilst I went off to pay some bills.

....
I had the vehicle valeted earlier today ....

 ..... and having doors open for hours won't have helped a struggling battery. 

This is what I cant understand Andy  :-?

I used a booster pack to start it at my house, then drove straight to Halfords for a battery (540amps, £54 with trade card).

I had the car valeted after having the new battery fitted, and not once today have I noticed any of the usual signs of a weak battery.

I haven't got a multimeter though, so I cant check it 

So, it's got its new battery on & you still can't lock it via the fob? How about via the driver's door lock?  :-/

Difficult to say Andy.

The car has been sat in my garage since mid October whilst I've been doing all the jobs to it. All this time it's been in my garage I haven't locked it.

All I can say is that I only noticed the hazard warning lights flashing (after unlocking the car) after I had had the new battery fitted.

Although TBH I wouldn't read too much into that bearing in mind what I have said above?

Sadly i dont think the rubber boots are available for the v6 cp llike they are for the 4 pot. So new cp i guess? 

I think your right. I've tried a few places and no-where seems to stock them. Well, not unless you want a coil pack free of charge.

It's a new car battery that I got for £54 from Halfords Andy, not the battery for the remote.

I don't think even Halfords could get away with charging £54 for what is essentially a watch battery

Some of those fault codes might be old - the no6 misfire and the transponder ones in particular

It's definatly missing TB. Running on four cylinders I reckon.

Is it possible to clear the fault codes at home, so that only new or current ones show?
