Oil leaks at the valve casing, worn timing belt components, and uneven compression vary quite a bit depending on which motor the car has. That's why the parts are grouped by motor family, so you go straight to the right one without mixing up the four-cylinder OHC blocks with the V6s.

Among the four-cylinder units there are the B21, B23, and later B230 (all 2.1–2.3 L OHC), plus older B variants. Those looking for the diesel side will find the D24, and the V6 versions are gathered under B27/B28. Cylinder head parts, soot cleaning kits, and seals are typical checkpoints during a rebuild.
