The noise seems to be coming from the back where the injectors are, I checked and adjusted the valves when I put head on and doubled checked 3 times. Brought 4 brand new injectors now, car done 135000 miles so new injectors might be good.
Will put them in see how it goes, if noisy still , then I will recheck valves.

It takes ages for them to settle down and bed-in after major work or even slight adjustment.
It also takes skill and experience to do them properly, and 99/100 times they are adjusted with too big a gap causing 'raspy' engine once it warms-up, or even pinging of a valve or two depending on the condition of the setup.
I strongly recommend opening the lid only after 200 miles and every 300 miles thereafter until you are fully happy with the torque/noise ratio, and fuel economy will also improve.
The TU3 is a good engine but usually the valve tappets cause this characteristic noise which so many people think it's the injectors.
However, let us know please when you replace them. 
Cheers.

Can I ask did you adjust the clearances in the correct order and when cold?

New fuel injectors in and car runs really nice, feels little quicker. Tappet noise still there, i have checked them while cold has per haynes manual, and they are all spot on. I would not say they are really loud.
Happy with the car now, just going to improve the brakes then car all done.

Did you put a bend on the end of each feeler gauge?
Did you leave it overnight when you say engine cold?

OK good to re-check them after a while.
Best of luck.
