Does the light smoke smell like fuel? As has been stated, check the injection timing and chain stretch as well as filters and fuel. Also check and make sure the EGR and flapper valve in the intake are working properly. If for some reason the flapper gets stuck closed it will starve the engine of air and it will run very rough with lots of light smoke (fuel) out the pipe.

Oil pressure should be pegged at 3 bar when the engine is cold. A fully warmed up engine should idle between 1 and 2 bar; anything over about 1500rpm should peg it on a warm engine as well.
