Hi
When your diesel engine produces white smoke it means that the fuel that was put into the cylinder is not burning properly. It may be because your engine is timing out or it is fuel starved to the pump making the pumps timing not to function properly. It may also be that there is low engine compression or there is water in the fuel

It proberly is not this but worth a try as its cheap and quick, either see if there is water in the fuel filter, you should be open to let this out with the screw on the bottom of the filter (passenger wheel arch side) or just renew it. I had white smoke a while back almost like thick fog coming from the exhuast and my mechanic told me to renew the diesel filter after I did it run completely clear.

Has it just started? Or been there for a while?
Mine runs fine all year round, then during the cold months.... it bellows cold smoke until the engine warms up. I'm told, this is nothing to worry about, so it might be the same for you - especially if you've just purchased the van?

I purchased mine at Christmas time and the roads ere freezing! I also thought I had a major problem with loads of white smoke. But during the warm months, I get nothing at all. And the white smoke soon passes.

Look out of the back of loads of other cars on the road, plenty of them emitting white smoke during the cold mornings

Is it an 88 or 102 ?

Has the timing been checked and confirmed to be within spec ?

Are there any fault codes ?

Check the coolant temp sensors too before spending too much.

If the smoke disappears after running for a while,it could be your glow plugs not working.
