Replacing the tensioner piston is very easy. It unscrews from the exhaust side of the timing chain. Very easy to replace in a matched set (cylinder and piston). My M made noise when I bought it and continues to even after replacing the timing chain, tensioner piston and two of the timing chain guides. I didn't replace the tensioning guides that the piston pushes on. They were big bucks. Didn't look to warn either. For you to replace any of the guides requires most of the front of the engine to come off. Depending on the noise, if it is just valvetrain noise, you may want to live with it. The timing chain and guides are supposed to live until the first rebuild (150k or so).

Have fun

My 88 M3 (58,000 miles) is starting to rattle on startup and I believe the chain tensioner may need replaced. Is this a do it yourself job? Any recommendations from those who have replaced the chain tensioner would be helpful.
