#### 1982–92 STANZA WITH THE CA20, CA20E AND KA24E ENGINES

NOTE: On Stanza models from 1987–92 (except 1986–88 station wagons) no routine valve adjustment is necessary or possible these models are equipped with hydraulic lash adjusters, which continually take up excess clearance in the valve train.

NOTE: Datsun/Nissan recommends that valve adjustment should be done every 12 months or 15,000 miles.

1. Run the engine until it reaches normal operating temperature. Oil temperature, not water temperature, is critical to valve adjustment. With this in mind, make sure the engine is fully warmed up since this is the only way to make sure the parts have reached their full expansion. Generally speaking, this takes around 15 minutes. After the engine has reached normal operating temperature, shut it off.
2. Purchase a new valve cover gasket before removing the valve cover. The new silicone gasket sealers are just as good or better if you can't find a gasket.
3. Note the location of any hoses or wires which may interfere with valve cover removal, disconnect and move them aside. Remove the bolts which hold the valve cover in place.
4. After the valve cover has been removed, the next step is to get the number one piston at TDC on the compression stroke. There are at least two ways to do this: Bump the engine over with the starter or turn it over by using a wrench on the front crankshaft pulley bolt. The easiest way to find TDC is to turn the engine over slowly with a wrench (after first removing No. 1 plug) until the piston is at the top of its stroke and the TDC timing mark on the crankshaft pulley is in alignment with the timing mark pointer. At this point, the valves for No. 1 cylinder should be closed.

   NOTE: Make sure both valves are closed with the valve springs up as high as they will go. An easy way to find the compression stroke is to remove the distributor cap and observe which spark plug lead the rotor is pointing to. If the rotor points to No. 1 spark plug lead, No. 1 cylinder is on its compression stroke. When the rotor points to the No. 2 spark plug lead, No. 2 cylinder is on its compression stroke.

5. Set the No. 1 piston at TDC of the compression stroke, then check and/or adjust the valve clearance on Stanza (1982 model only) Nos. 1, 4, 6 and 7; on the Stanza (1983–86 and 1986–88 Stanza wagon), Nos. 1, 2, 4 and 6.
6. To adjust the clearance, loosen the lock-nut with a wrench and turn the adjuster with a screwdriver while holding the lock-nut. The correct size feeler gauge (0.012 in.) 0.30mm should pass with a slight drag between the rocker arm and the valve stem.

7. Turn the crankshaft one full revolution to position the No. 4 piston at TDC of the compression stroke. Check and/or adjust the valves (counting from the front to the rear) on the Stanza (1982 model only), Nos. 2, 3, 5 and 8; on the Stanza (1983–86 and 1986–88 Stanza wagon), Nos. 3, 5, 7 and 8.
8. Replace the valve cover and torque the bolts on the valve cover down evenly. Check oil level.
