Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).

New rocker arms (cam followers) are required during any new camshaft installation on the S54 engine. Otherwise the original rocker arm will wear the new camshaft lobe unevenly. These are the Original BMW S54 rocker arms and used on the original E46 M3 CSL cams as well. While these are fine for CSL cam upgrades or the Schrick 280/272 cams, the Schrick DLC rocker arms are better all around, especially when used with the more aggressive 288/280 or higher cams.

Priced per rocker.
