Valve Clearance

Cylinder head temperature must be less than 100°F (38°C). Remove valve cover, timing belt covers and distributor cap.
Align pointer on timing belt lower cover with TDC (White mark). UP marks on both camshaft sprockets should be at top of cam gears. Distributor rotor should point to No. 1 spark plug wire on cap. Adjust valves on cylinder No. 1.
Rotate crankshaft counterclockwise 180 degrees to bring No. 3 piston to TDC on compression stroke. Adjust valves on cylinder No. 3.
Rotate crankshaft counterclockwise 180 degrees to bring No. 4 piston to TDC on compression stroke. Adjust valves on cylinder No. 4.

Rotate crankshaft counterclockwise 180 degrees to bring No. 2 piston to TDC on compression stroke. Adjust valves on cylinder No. 2.
