Re: 156 makes awful noise when cold
Check your receipts to see if the variator or the big ends were done when the belt failed, for £1600 I would expect they were, but as you suspect, it may be a tappet, but not a sticking one, but one that drains quickly and the noise from that occuring can make you think your under attack from ZE germans, until it is filled up with oil again when the engine starts it will be noisey, it will though wear the cam in time so it is worth looking into.
Otherwise it could be steering pump or alternator, but you haven't mentioned a symptoms to go along with them apart from noise.
