If the lifters [automotive repair industry term] or hydraulic lash adjusters [actual terminology], which are ment to maintain the correct distance between the valve train components is bleeding off oil within the adjuster, it must be replaced. The only thing that can be done is to replace them. I would suggest replaceing all 24 [dual overhead cam engine type], if you are in there doing that, you may as well replace the valve stem seals as well... and believe me, its alot of work, ive done it..

That sound is one or more valve lifter(s) that is out of adjustment or a clogged rod provided your oil level is correct and the oil is not overly used and dirty. If there are several valve lifters making noise I would tend to believe the oil pressure is too low which could be the oil pump failing.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
Remove the valve cover.
Set the engine to Top Dead Center (TDC) of the compression stroke for the cylinder to be adjusted.
Check the valve clearance. The valve clearance specifications are as follows:
Intake valves: 0.005-0.007 inches (0.13-0.17mm)
Exhaust valves: 0.005-0.007 inches (0.13-0.17mm)
After adjustment, tighten the locknuts to 11-14 ft. lbs. (15-19 Nm).
Repeat for each valve to be adjusted.
1.8L, 2.0L and 2.5L Engines
The 1.8L, 2.0L and 2.5L engines utilize automatic hydraulic lash adjusters to maintain proper valve lash at all times. Periodic valve lash inspection and adjustment is not necessary or possible.
The lash adjusters are hydraulic and will have to be replaced. They can be replaced without removing the head, you just have to remove the necessry intake & parts that restrict your access to removing the valve covers, then remove the rockers (that's where the adjusters are of course), replace the adjusters and reassemble. Make sure you note the direction of everything, once reassembled it should fit exactly as it did before, with a little less slack.
All engine parts like this need oil. Soak the valve lash adjusters in oil overnight before installing, preferably in a warm location, or place a warm light next to the container you put them in, they work like valve lifters, just smaller.
The EA82 does not use shims. Ticking almost always caused by a failed oil pump to engine block gasket failure. The gasket slowly fails which then allows the oil pump to pump air along with the oil. Replace the "Mickey Mouse" oil pump gasket.
