Cylinder head Volvo B21
Oil leakage along the cylinder head joint, coolant in the oil, or a rough idle after an overheating are classic signs that the gasket on the 2.1-liter OHC engine B21 has given up. Once the head is off, it pays to check it for flatness and replace the seals in one go, since tightening the cylinder head bolts requires clean, undamaged threads for the correct torque.

This category gathers parts for sealing and assembling the B21 cylinder head. The group includes cylinder head gaskets and complete gasket sets, cylinder head bolts and studs, hoses, lifting eyes, as well as cap and ordinary plugs. The families cover both the sealing layer itself and the bolted joints that hold the head in place.
When rebuilding, the flatness of the cylinder head and the condition of the bolts are typical inspection points – stretched bolts and a crushed gasket are common causes of recurring leaks on the B21.
