Default 16V chain tensioner pads replacement

Just finished replacing the pads of my new to me '89 S2. It is one of the items on the long check list I made before I drive the car on the road worry free. For my big surprise the banjo bolt of the J tube at the tensioner was hand tight only which got me worried a bit. However, the cams look in excellent condition with no pitting or abnormal weae on the lobes and the sprockets look almost perfect too.

The pads in the car were 6 years old and with 57000 miles on them. I wanted to share some pics of the old vs new. The car has been maintained very well over the last 6 years and during half of that time it has been driven on the track as well.

Here are some pics. Notice the pitting at the end of the top pad. It looks almost as the material that it was made was porous and not solid.

I did mine last year after reading so many horror stories. Mine looked even more gouged than yours but they still seemed strong and were not brittle.

A no brainier for piece of mind tho.

The pitting is normal, most likely due to cavitation of the oil.

What you want to avoid is wear tracks that are deep enough to allow the chain roller to start running on the pad, this accelerates chain wear. Looks like you got to this one in time - good work!
