Crankshaft Volvo B30 (1974-)

Oil leaks at the crankshaft seal, oil consumption or a rattling cam drive are classic signs that the crank motion in a B30 needs attention. The inline six is considered very reliable and handles high mileage, but piston rings, seals and cam gears are wear parts that belong to a proper engine rebuild.

This category gathers parts for the B30 from 1974 onward in the Volvo 140/164. The group includes piston sets and piston ring sets, cam gear sets, seals, support plates, protecting plates, hubs and screws. During a rebuild it is worth measuring the cylinder bore and checking ring clearance before selecting a piston set – oversize affects which piston ring set fits.

Since the B30 was built in both carburetor and fuel-injection versions (B30E/B30F), it pays to check the details against your engine before ordering.
