• Q: What is the recommended maintenance interval for valve lifter adjustment and what tools are required for the process on 1997 Volvo 960?

  A: The valve clearance must be changed after every 30,000 miles (48,000 km). Not every Volvo operates on adjustable valves, B230F and B230FT are adjusted unlike the rest of the engines, which have non-adjustable hydrostatic tappets. Adjustments require special tools such as a feeler gauge. Oil checks and replacement or changing of valve adjusting discs are involved.
