Not me, although I think you might want look at your valves depending how many Ks on the motor. Diesel oil immediately goes black due to the compression. Your injector pump is probably the same as mine and the manual states that timing can cause smoking, but if you've adjusted it, then you might look at stem seals which unfortunately means pulling off the head, and while you're at it you should pull the valves, clean and lap them back in. I hope thats helpful, I can't think of anything else that would do it at the moment.
