Q: How to check and adjust valve clearances for the Honda Del Sol?
A: Check and adjust valve clearances with a cold engine. Set the number one piston at Top Dead Center (TDC) by aligning the timing pointer with the TDC mark. Ensure the Distributor Rotor points to the number one Spark Plug Wire terminal. Remove the valve cover and adjust the number one cylinder valve. Use a feeler gauge to check the intake valve clearance and adjust if necessary. Repeat for the other intake valve and the two exhaust valves. Rotate the crankshaft pulley 180-degrees counterclockwise for each subsequent cylinder (three, four, and two) and adjust their valves. Reinstall the valve cover.
