A leaking seal between the inlet manifold and cylinder head can cause a rough idle and false air, and should be checked when the B230A four pulls in extra air. This category gathers the small parts that keep the intake sealed and correctly mounted on the Volvo 740 with the intake manifold for the B230A.

The group includes studs and adjusting screws, seals and copper washers, plus stoppers, plugs, nipples and the axle that belong to the pipe connections. When refurbishing the intake, threaded studs and their copper washers are typical check points – corroded threads and hardened seals are common causes of slow leaks. Since the parts are coded specifically to the B230A, the engine code and connection type should be verified before ordering so that the thread dimension and sealing surface fit.
