Question:  Where can I purchase eight Febi Valve Lifters - the ones with the
sturdy c-clip holding the parts together? I understand they are the better ones!
I currently have the ones with the paper clip holding the parts together.
My 1984 1.9  Westfalia starts & runs fine with no valve noise but after driving for about
an hour at 60 - 70 mph or so then the engine loses power and the valves become very
noisy.
