How to adjust valves 1990 Nissan truck KA24E?
Not sure if this helps but I have a 95 nissan pickup ka24e which requires no adjustments (self-adjusting). Check the sticker on your hood/rad support/firewall for lifter adjustment information. If it supplies a measurement #.## then you get some feeler gauges, pop the valve cover, loosing the bolt with a boxend wrench, turn the stud with a flathead until the clearance is set (with the feeler gauge) and tighten the bolt, move on to the next one. I believe you need to manually crank the engine so that you adjust on the low part of the lobe.
