my 06 td4 was gutless at low revs and produced blue smoke on start up.i changed all filt.ers including a very oiled up crankcase filter. It's now a different vehicle.no smoke and pulls away a treat.
threads mention removing 4 screws on bottom of housing.my 06 freelander has 6mm hex head screws. I had to grind down a 6mm socket in order to remove these screws.
