JamesV6CDX - before ripping engines apart, do the std service - fuel filters, ait filters, oil, breathers and so on.

All in the plan - in fact, is what I was doing tonight :y
So stop moaning about economy until those basic steps have been done ;D

Not moaning - but I see that having the valve timing right IS a crutial step towards getting it spot on, don't you agree? ::)
As is doing the basics.

Not disputing the basics make a difference -

But for the purpose of the question assume that is done, but the two cams are still slightly out.

Will half a tooth out make a noticable difference to either performance or economy,  in your experience, yes or no ;)
Slight difference, yes, but not enough to account for your economy.

Thanks :D

In which case, once that's done, COMBINED with a full service, it should be somewhere towards better :)
I would have done it the other way round - a known good service that then gives you a baseline to start from.

I agree, but poor economy aside, I had a bigger concern, about no cambelt history.

I'm sure you'll agree that any Omega purchase with no cambelt history needs a kit put on there as a priority :y

And under the circumstances, it's a blessing I'm not driving it, given the state of the cambelt kit ;D

Omega ECU gives response to how you drive..if few hours you drive in sporty style ECU increases the fuel..This is my experience if I'm not wrong..

ps: assuming other engine parameters in good condition..


one thing to add , even a very small leak on exhaust line can effect

consumption

Always best to have all settings correct, as they say in Tesco, every little helps.
