HELP SMOKE PROBLEM

[ksp123]

Hi my 58 plate belingo smokes from exhaust and smoke was coming from what looked like under air box. so i took the air box off and it stopped smoking from exhaust. the smoke smells a bit funny can anyone help. i also took pipe what goes from inter-cooler to turbo and it was oily. :S

How much smoke and what colour?

[ksp123]

Not a lot and blue/white its hard to tell.

If it stops smoking when you remove the air box is the filter blocked?

I wouldn't get too bothered about a small amount of oil in the inlet pipes, it's quite normal, at least it is on the three diesels I own.

The smoke seems to be coming out of the top of the engine where the air pipe goes from center of the turbo to the air box do you think it's the vavle seals?

I'm assuming that you have the 1.6hdi. If by "the top of the engine where the air pipe goes from centre of the turbo to the air box you mean the end of the plastic rocker cover, or oil separator as the Haynes manual calls it then this will be oil vapour from the crank case, which condenses and forms the oil in the pipes as you describe.
I would chuck it back together with a new air filter and see if the exhaust smoke improves. If it is burning oil via the seals then it will smoke more on start up and the smell of engine oil being burnt is quite different to the smell of normal diesel fumes.
Whilst you are under the bonnet make sure that any smoke isn't coming from the area of the injectors as blow by leaks are quite common on these and can cause huge problems if not fixed quickly.
