Hi smith 4130, I'm a bit of a newbie,I haven't posted or replied but I have been a member while and done a fair bit of researching etc.on this site so here goes,I've just finished a top end overhaul on a 2.5 tdi AFB in my a6.It all started when I was replacing the belts etc.on tuning the engine over by hand it had a suspect click from the righthand bank,so I stripped the cover off only to find two of the cam followers had dissapeared and the tops of the hyd.lifters were not in good shape. the clicking sound tuned out to be another follower nearly leaving the hyd. lifter. So I stripped the other side off to find one follower gone.luckly the parts were still in the heads.The outcome of all this is it had to have 24 new cam followers and follower pads, 24 hyd. lifters, cam seal gaskets etc.The job is very fiddly and time consuming but you can leave the heads on,the genuine parts aren't too badly priced,in my opinion you do need a good degree of mechanical skills to tackle the job I have been working with cars for a long time,if you do have a go be extra clean,lay all the parts out in order etc. if you fit new lifters don't forget to VERY slowly compress the oil out and graphogen grease the followers this help lube. before oil pressure comes up and it will also help to hold the followers in place during assembly,good luck any problems please reply.:icon_thumright:
