1989 Volvo 245 Intake Valve Parts and Q&A

• Q: How should the intake valve clearances be adjusted to ensure the correct setting after engine operation on 1989 Volvo 245?

  A: Adjust the valve clearances to be between 0.002 in (0.05 mm) more than the specified values, and make sure the correct setting is obtained after the last cylinder head tightening after engine operation. The simplest method of adjusting the clearances is by using two feeler gauges, one for the lower limit and other for the upper limit, adjusting so that the thicker gauge cannot fit in between the rocker arm and the valve while the thinner gauge easily fits in between. It is important to set the valve clearance when the tappet is set away from the peak of its cam. adjustment should be done in a certain order to reduce unnecessary crankshaft rotation. For people unfamiliar with the process, the locknut on the rocker arm should be loosened, and the screw adjusted up or down to adjust the rocker on the pushrod, so that the user can identify the correct fit of the feeler gauges. When adjusting valve clearances as part of your routine service with the engine in the car you should first remove the air cleaner and rocker arm casing and it should be noted that adjustments can be made regardless of whether the engine is cold or hot, with a new gasket when refitting the rocker cover.
