Valve mechanism Volvo B28
Blue smoke at cold start and oil consumption with no visible leak can point to worn valve seals – a common check point on the V6 engine once it has covered a lot of miles. This category gathers intake valve parts for the Volvo 740, 760 and 780 with the B28 engine, that is, the components that control valve movement and sealing against the cover.
The group includes inlet valves, valve seals, chain sprockets and screws. During a cylinder head or valve overhaul it is typical to check the valve guide clearance, replace the seals at the same time, and inspect the chain sprocket for wear before everything is reassembled. Since the design differs between engine variants, it is worth checking the part's fit against your specific B28 before installation, so that valve clearance and sealing come out right.
