how do I replace camshaft on 1.7 diesel fiat fiorino van?

Without sounding rude to you.
If you haven't got a clue how to do this repair I wouldn't attempt it in the first place.
I have been in the car repair trade for over 25 years and I am still learning new things all the time.
You may end up costing yourself a lot of money in the long run.
