Valve mechanism Volvo B20A/B/D

Blue smoke during engine braking, rising oil consumption and clatter from the valve side often point to worn valve guides and tired valves on the B20 motor. As the guide clearance grows, oil is drawn down along the valve stem and compression drops on individual cylinders – a typical rebuild situation on the 1800S, 1800E and 1800ES.

This group includes camshaft kits, inlet valves and exhaust valves, valve guides, push rods plus cam gear sets and thrust flanges – sub-families that belong together once the cylinder head is opened. Shims for clearance adjustment are included to set the valve clearance correctly after a new valve and guide.

Measure the camshaft lobe height and check the lifters' wear surface before choosing a new camshaft kit – a worn cam gives sluggish throttle response and an uneven idle. Combining the camshaft with a matching cam gear and thrust flange keeps the valve timing correct across the entire rev range.
