How do you adjust the valve clearance on a 1994 Prelude 2.3 engine?

You need to take the valve cover off and set the engine to TDC for #1 and then TDC for #3 and so forth. you NEED a set of feeler gauges, you need the repair maunal to find the proper adjustment clearnces unless it is on your car's engine decal under the hood. (rule of thumb, adjust the valves when engine is under 100 degrees, also there should be a SLIGHT drag of the proper feeler gauge when the its set right.)
