Recon. Vauxhall Movano engine

[LBird]

I have urgent need of a recon. (or new) Vauxhall Movano engine, 2.5 litre turbo diesel, GU9. Can anyone recommend a reputable supplier, preferably in the Midlands but anywhere will do!!

Many thanks :-)

Poor compression on all cylinders, difficulty starting, running rough at idle, belching out clouds of black smoke.... :-(
