The valve clearance specification for a Volvo FL10 truck depends on the specific engine model and year of manufacture. Generally, the valve clearance for the FL10 truck with a Volvo D10 engine should be checked and adjusted as follows: Remove the valve cover: Remove the valve cover to access the valves. Rotate the engine: Rotate the engine to the top dead center (TDC) position for the cylinder you want to adjust. Check the valve clearance: Use a feeler gauge to check the clearance between the valve stem and the rocker arm. The specification for the valve clearance should be listed in the engine service manual. Adjust the valve clearance: If the clearance is not within the specified range, adjust the clearance by loosening the lock nut on the rocker arm and turning the adjustment screw. Tighten the lock nut when the clearance is correct. Repeat for each cylinder: Repeat the above steps for each cylinder. Reinstall the valve cover: Once all the valve clearances have been checked and adjusted, reinstall the valve cover. It is recommended to refer to the engine service manual for specific instructions and specifications for your particular Volvo FL10 engine.

lacking manual or engine name, i'd look first.

Valve clearances are the small gaps between the tops of the valve stems and the part of the mechanism which presses on them to open the valves . Check the clearances at regular intervals as specified in the car service schedule, and adjust if necessary. Reset the clearances whenever the cylinder head has been removed.

Incorrect clearances can cause the engine's intake and exhaust valves to fail prematurely, which can lead to engine idle and drivability problems, as well as excess pollution. ... If the valves are too tight, the vehicle may also exhibit rough running characteristics either cold, hot or all the time.
