I suggest you take off the tappet covers and see if anything is broken there . Other places where there may be circlips are the distributor and oil pump, however these may be more difficult to reach. If you don't find anything under the tappet covers you can then drop the sump. This is messy but not too difficult. With the sump off you can normally reach the oil pump. If you take out the distributor be careful to put it back with the shaft in the same position or your ignition timing will be out and the engine won't run.

Hydraulic lifters can hang up or become sticky, so it depends on many factors, as in, is oil clean, how often you change oil, what type of oil, and what weight oil are you using. You can try an oil flush if you are not one who changes oil at proper intervals, this is usually why a hydraulic lifter fails.
if hydraulic tappets then do this darin a drop of oil out of the engine so its about min on the dip stick then add some diesel to the oil say about half a litre then a good three capfulls of fairy washing up liquid ,has to be fairy though then run car for a week and the noise will abait ,now change the oil and the filter and use the cheapest diesel/petrol engine oil you can buy must be for diesels as well though then every 5000/6000 miles change it with a filter every third oild change and your engine will run as sweet as a nut and last for ever
no what you do is to add a half litre of diesel to the oil and 3 good squirts of fairy liquid ,got to be fairy and no cheap one.then run vehicle around for a day or so and the noise will stop ,Then change oil and filter and from then on change oil every 5000miles and a oil filter every third oil change ,use a diesel/petrol oil the cheapest you can buy and the diesel /petrol oil will have detergent in it which will keep the inside of the engine clean and prevent clag from forming which is what is causing your hydraulic tappet stick thus making a noise .
three squirts of washing up liquid ,has to be fairy not a cheap one ,half a litre of diesel all added to the engine oil ,run for a couple of days as normal and the noise will diminish ,Then change oil and filter but use a 10/40 detergent oil suitable for a turbo diesel ,the cheapest you can buy ,now change oil every 6000m with a oil filter every third oil change .You have a noisey hydraulic tappet nothing more which is fairly common on this engine and its caused by not changing the oil enough and using expensive long life oil which causes problems like yours by allowing the combustion residue to accumulate within the internal workings of your engine ,
put half a litre of diesel in the engine oil and three good squirts of fairy liquid ,leave for week then change oil because it will be quiet ,use a ordenary oil for a diesel turbo engine ,cheapest from supermarket,and a filter then change the oil every 6000miles with a oil filter every thrid oil change andf you will have no problems with gunged up hydraulic cam followers
put some diesel in the oil about a half a pint ,3 sec squirt of fairy and then run engine for a couple of days normal use ,then drain oil and use the cheapest diesel oil you can buy ,after a month change the oil and filter and your hydraulic tappets should be nice and quiet,then make sure you change oil every 6000miles and a oil filter every third oil change and no silly long life semi this or that oil ,just the cheapest 20/50 diesel engine oil .
put half a litre of diesel in the oil and three second squirt of fariy liquid ,no cheap stuff allowed ,run for about a week and drain oil,then with the new oil in ,using the cheapest diesel oil you can get repeat again with diesel and fairy ,by this time they should have quitened down a lot,then change oil again using a diesel oil for a turbo truck change filter as well and then change oil every 6000 miles and a filter every third oil change
add a litre of diesel and a 3 sec squirt of fairy washing up liquid ,use vehicle for a week and see how it sounds ,if its quietened down a bit ,change the oil and use a cheap diesel engine oil and then add some more diesel and fairy and leave another week ,if it still hasnt quiented down then strip and repair ,is has quietened down the change oil again for good measure and use the diesel engine oil as its a detergent oil and then change oil at approx 6000mile interval no longer and use the cheap oil .Change oil filter every third oil change and you will not get a repeat of the problem.Use an expensive long life oil and the problem will re appear ,because the additives and combustion residues will clog up and stick the hydraulic valve lifters
what this sounds like is that your engine is starving for oil and the tapping noise is yuour rocker arms. this could be due to sludge build up on the intake screen of your oil pump or the pump itself is weak and no longer is providing the needed oil pressure. another place for sludge to build up is the valve covers and until the engine heats up very little oil is circulating to the push rod,rocker arms, and lifters. my suggestion is to clean the valve covers, drop the oil pan and remove the pump to look at the gears to see if there are missing teeth. also clean the screen of the pick up tube. replace the oil filter and put in new oil also use lucas additive this will do a good job of keeping the sludge build up to almost nill. if the problem persists then i would say that one or more of your hydraulic liftyers is weak and then they will need replacing.
