A rattling noise on cold start or a clattery idle can point to a stretched chain or worn adjuster rails in the B27's cam drive. The V6-built 2,664 cc engine sits in the 260 series, and over the years both chain and plastic rails lose their tension – a common check item when you're already in at the timing cover.

This category gathers parts for the cam drive on the B27: chains, chain sprockets, adjuster rails and the seals needed at reassembly. The group also includes gaskets, hexagon screws and spring washers that belong to the mounting. Check the adjuster rails' wear grooves and the chain play carefully – if you replace the chain it's often wise to look over the sprockets and rails at the same time so the new parts don't wear out of step against old ones.
