    At last this one is fixed.
    I have been away on holiday & while i was away the customer replaced the piston rings & had the valve stem seals replaced as it was burning oil.When the vehicle was brought in agsin to check the emissions,initially the emissions came down & would have passsed an mot,but when it had warmed up they went up to about 2.5% co.The only thing that was bugging me was the non genuine NTK oxygen sensor & the fact that somebody had mentioned that these engines were fussy on lambda sensors in the archives.I suggested that the oxygen sensor could be the problem even though it would switch ok for a bit when the fault was cleared, so he decided to replace it with a bosch sensor from GSF & the emissions are now spot on thankfully.It's very anoying when a usually good make of sensor is fitted only to find that it was the casue of the fault.
    Sorry for the long post,hopefully this will help somebody.
    Kind Regards,Andrew
