The cam belt broke last week and the valves had to be replaced. The engine is now running again, but one of the tappets are noisy.

well, I can see ur message has been here for quite some time. Most probably you got the answer to ur request.
I just did the valve clearance on the engine of my SJ413 that has the 1000cc engine of an SJ410 :
When cold: 0.13mm Intake and 0.18mm Exhaust
Engine sounded well and worked fine after that.
Enjoy

SOURCE: Engine tappet clearances
According to http://freespace.virgin.net/tommy.sandham/databook.htm# Rocker Adjustment, the cold clearance is .008" intake/.018" exhaust in the non-GT 1500cc, and .012" intake/.022 exhaust on the GT. Sweet little car!!!
SOURCE: no oil pressure on an audi 2 liter 20 valve engine
Did you check the pressure first? Noisy tappets don't necessarily mean low pressure, sometimes they simply wear out.
Otherwise, either your oil pump is bad, or the oil pickup screen located inside the oil pan area is clogged up. Clean the screen first and then check the pressure...
SOURCE: how to measure tappet clearance with dial gauge
When setting tappets, it has to be born inind that the valve stem wears an indentation into the face of the rocker. This prevents a really accurate tappet adjustment, so the customer is right again. If you do not posess a tappet setting dial gauge, a normal engineers dial gauge will do just as well. The procedure is the same as using your feeler gauge except that you set the dial gauge up on the cylinder head with the pointer resting on the head of the rocker. Press down fairly firmly on the rocker valve end and zero the gauge. Next lift up on the rocker and read off the clearance, from the gauge, Use a magnetic base to support your gauge and repeat the pocedure for each valve pair.
