Smoking 75

Hi All

I have a 2005 Rover 75 diesel (M47r) Tourer.

It was getting harder to start and eventually refused altogether .... did a leakdown test and the injectors were suspect .... took them to a reputable diesel specialist and they were goosed. Bit the bullet and got 4 genuine new Bosch replacements .... fitted them and the car starts perfectly now.

The problem I have is that it now smokes (light blue smoke so likely oil rather than fueling issues?) ... when started from cold it's mild at tickover but a proper smokescreen at steady mid revs .... disappears after half a mile or so but back on the next cold start.

It didn't smoke with the old injectors and it's hard to see valve seals, rings or turbo seals spontaneously failing while it was parked up a couple of days while I sourced the injectors.

Got me scratching my head .... have cleaned the PCV filter in parrafin as it was fairly dirty ... no change.

Any suggestions of things I may have forgotten to reconnect or disturbed (have rechecked but it is still me doing it!) .... basically any thoughts really.

Cheers

Ps ... in case the pcv is still not up to par does anyone know if I can just leave the filter out of the housing for a static cold start test to eliminate it?

Also this is my first 75 (and I love the car) so I don't have much specific knowledge on the marque .... my wife's Audi had a 'learning' ecu ... does the Rover? ... and is it possible it's adjusted for the dodgy injectors and needs time to readjust to the shiny new ones (only done 5 miles test run since the change)

Many Thanks
