id heard before you can strip and clean the hydraulic tappets found on most later vw's(85 ish onwards) its nearly always the reason they tick
1, take your tappet and slam it onto some wood as hard as you can , might take a few goes for the center to fall out
2, work over a sheet of white paper as the parts are tiny , the small cap on the left simply pops off with some pliers to reveal a spring and a ball bearing , take some time to clean all this up and reassemble with some clean engine oil , the center take a good shove to click back in place
