Rough idling, jerky throttle response or hard starting in a B28F-equipped Volvo can point to wear in the ignition distributor. A burn-tracked distributor cap, a tired rotor arm or a leaking vacuum regulator are common checkpoints when the spark no longer reaches the right cylinder cleanly.

This category gathers distributor parts that fit the B28F. The group includes a distributor cap, rotor arm, vacuum regulator and impulse sensor, plus smaller wear parts such as a lock ring, spring washer, screw and grease for installation. When overhauling the distributor it is wise to check the inside of the cap and the rotor contact surface at the same time – cracks and burn marks disturb the ignition pattern more than you might think.
Since the B28F is a V6, the fit of the parts should always be verified against your engine variant before replacement.
