Omega General Help / Re: changing thermostat on the mv6

made even worse with the longitudinal engine installation

In think being longitudinal makes the majority of jobs easier. Certainly wouldn't fancy doing a cam belt on a FWD V6.

I take it you haven't had the "pleasure" of changing the coil pack?  Buried right at the back of the engine, up against the bulkhead.

Slightly off-topic reply, but I it think perfectly illustrates how some simple jobs on the GM V6 engines have been made much harder than they could have been, made even worse with the longitudinal engine installation:

I used to drive a Rover 620 Ti (petrol turbo model, 200bhp, yada yada), which for some reason required a new thermostat every 8 months or so.  If left unchanged, engine would start to run too cold, and would start to idle at ever increasing revs, going from 750 RPM to 2000 RPM over a period of weeks (2000 RPM = 174 lb ft of torque in the T16 engine).

This wasn't a big problem, because thermostat and gasket only cost £7 from Rover, and took only 10 minutes to change... sometimes I changed it in the rain before driving to work, sometimes during my 15 minute break from work, once even at 9pm in the dark on a January evening.

Moral of the story?  Imagine if an Omega developed that kind of fault and you had to change the thermostat in a hurry...!

Shouldn't your 96 model be a 2.5 rather than a 2.6?

Omega General Help / Re: Alarming scraping noise

« on: 02 October 2007, 09:23:26 »

My car made a scraping noise when turning right when I first drove it home after buying it.  Turns out the tyres were scraping the front mudflaps when turned to the side, mostly because of the 225 tyres.

I remember reading some Vauxhall promotional material back in the late 1980's or early 90's, and it said they fitted heavy duty wheels to the cars they sold to plod, to help them mount kerbs.

It sounds like the nut that holds the wiper arm on has come loose, so the wiper arm has now let go of its spline drive....

Yup...happened to me on a mk3 Cavalier. You'll probably need new wiper arms now, I'd be surprised if they haven't gotten bent.

The insurance is going to be affected as well by doing engine modifications.

Only if you tell them - as an ex-claims manager, I know that the insurers and their engineers that inspect written off cars aren't set up to look for these kinds of engine mods...they look for non-standard wheels, body kits, big exhausts etc.

I think with these cars they care little anyway, I have quite a big mod already and it made no difference to insurance. (My LPG kit), towbar made no difference either.

Insurers definately wouldn't care about towbars and lpg conversions - they don't make the car go faster and don't make them more attractive to TWOCers

For £299 Superchips.co.uk will give you an additional 13BHP and 24 lb ft...seems a reasonable place to start.

Omega General Help / Re: Mud Flaps

« on: 25 September 2007, 12:37:55 »

Had genuine ones on mine on all 4 wheel arches when I bought it used, couldn't figure out what the rubbing noise was when I went round corners as I drove home from the sale.  Had a good look the next day and saw that the front tyres were rubbing badly on the mudflaps when cornering, not helped by the 225 width of the tyres.  Binned the front mudflaps straight away.

Omega General Help / Re: headlamps

« on: 24 September 2007, 22:19:49 »

Have been using Philips Vision +30% (when that was the best they did) and +50% for many years, change them every 12 monthts, and can report they are much better than standard bulbs. (application: 1999 my with projector lamps).  They do create a bit of glare for the car in front, but in normal circumstances I have the headlamp levelling switch down 1 level, then move them up to the zero setting when someone is hogging the 3rd lane of the m/way even when not o/taking anyone....they get out of the way like Moses parting the Red sea.

What I don't like about the Philips bulbs is that the +80% "X-treme" bulbs aren't available in H1 format, even a year after H4 and H7 came out, and Philips UK advise they aren't likely to bother doing so anytime soon.  

Might move to a good set of aftermarket HIDs, but have the usual problem of the silver reflector being loose within the h/lap (both sides); this is fine with normal bulbs (passes the h/lamp alignment test in the MOT each year), but reckon the weight of the ballast and extra wiring might move the reflector too much, so would have to shell out £100 for a pair of new pattern-part h/lamps off ebay before then buying the HIDs.

Omega Gallery / Re: Last Ever Omega

« on: 24 September 2007, 22:35:21 »

Don't know about the last ever Omega, although wouldn't be surprised if, as posted further up, they were indeed all bought up by plod (they did the same when the Rover SD1 went out of production), but have seen the last ever Ford Cortina made, it used to be kept in the Ford heritage museum next door to the Dagenham plant, and despite only having 17 miles on the clock and having spent all it's life indoors, it still had rust on the edge of the bootlid  

Drove a 3.2 Elite Vectra for a long w/e when Vx were doing 48 hour test drives...when doing 80-ish on the m/way the car had a strange, slow, back-and-forth pitching motion, a bit like a boat in a storm...
