During the last few months the "tapping" noise in the lifters area has become somewhat louder in my 88' 190E 2.3 8vlv. The head has new valve seals and guides and the head was checked out for wear.

But I did not do anything to the camshaft/lifters area. I still have the tapping noise and was wondering if ordering the 8 hydraulic lifters listed in the shop would silence the noise... Is there anything else that I must buy besides the hydraulic lifters???
