Flattered I am, but sorry dude I am not an expert.  But I can diagnose the problems these guys are throwing out of their expert brains. 8-)

BTW, I cant remeber the last time I had a lie-in.....  :'( :-/

Right, just got back from dougies place after looking at his car.

Earthing point - secure no corrosion no reason why it should cause the problem.
Timing belt - not slipped, timing correct, belt and tensioner condition pretty fair
EGR - blocked off makes no differnce whatsoever
Checked plugs and HT leads - plugs seem fair but could do with changing soon.  HT leads rubber is cooked, rocker cover gaskets are leaking but the metal inside is still pretty clean.  Although these need to be replaced after the breathers and cam covers are done I dont not think this is the cause of the problem.
Exhaust - OMFG!!!  Looks like the previous owner has fitted a very wierd cat on the passenger side.  It was about half the size of the opposite side and the lambda sensor was mounted in a putty/wire bracket.

IMHO I think the cat is blocked because:
-the cat is much smaller than it should be and I do not think it can handle the throughput from the v6 and shed it fibres. It doesnt even sit right (much higher than the other side.
-the exhuast fumes coming out the back are bitty and not constant like on mine
-the problem came on suddenly and was not a gradual decline
-nothing else seems wrong

Unless it is the fuel filter that is blocked I cannot think of anything else that could be wrong.  It is worth noting that the previous owner was a bit of a cowboy looking at the work that had been done.

If you get some vx rocker gaskets and some carb cleaner (plus the HTleads and spark plugs) we can help you out at the next meet in tidders.

P.S the site for Micheldever tyres who do good exhaust deals is not working but here is the number 01962 774437

A billion thanks to mrgaffney!! Thank you!! (Also, you left your Haynes manual in my Garage..)

Ok. I've decided to go down the route of buying and changing the exhaust myself..
I'll go for the cheaper version for £250 as prices in Garages ranged from £650 (Micheldever) to £1175 (GM)

Has anyone had the experience yet? I know the nuts will be difficult to get off, but does anyone have any tips?

Doug,

From reading other posts on here I think your best most cost effective route would be to source a GM exhaust and find a local garage to fit it for a few notes.

Should end up around the £250 level if you can get it on TC.

Cheers

Yes but, you cant buy one decent cat for that price and hence they will be shite and not worth the money......

Good second hand cats.....plus a Vx system on trade club is the wy forward....

Has anyone got a tradecard I can borrow?
As much as I love the Omega, 1) I'm not paying 4 times the worth of the car on an exhaust, and 2) I don't really want the car to outlive the exhaust, as it probably will..
I can't afford £1200...
If I can get it on TC for £300 then I have the mechanic friend to fit it for me if need be..

You can always join Autobahnstormers for £20, but I know there are several trade cards not far from you who will likely volunteer in a short while...

Ok...Finally got my BackBox off.. TOTALLY clogged with furry fibre glass stuff..
Mid boxes also buggered.. Banging them; sounds like they've got sand in!  :-[

Started the engine; obviously very noisey, but engine runs a dream compared to before!
Think I've found my answer!


I just wanna thank EVERYONE for their quick replies, and pointers to dianose this beast!
Big thanks to Matt also, for coming out here, and helping me, (well, doing all the work) narrow down the causes and checking my aux/cam belts.

Thanks Thanks Thanks!

And as a warning about crap non-vx exhausts, last July I had fitted the middle and back box at a local place, today they have replaced the middle section under warranty as it had failed in under 8k? Lucky I kept the receipt.  :-/
