Oil mist on the block side, moisture around the valve cover or suspected leakage after a cylinder head overhaul are common reasons to inspect the seals on the B17 engine in the 240/260. When the cylinder head is lifted for decarbonizing or surfacing, the gaskets should always be replaced at the same time – old material rarely seals up again.

This group includes individual gaskets, complete gasket sets, completion kits and a soot cleaning kit. The kits gather the seals that belong together for one and the same job, which makes it easier to get the right parts in one go instead of hunting down loose gaskets. Always check that the kit matches your B17 variant before installation.
