hi,

in performing a tune up, what is the proper way of turning the crankshaft prior to measuring the gap between the rocker arm and the valve stem? This for a 4g15 sohc lancer engine.

kasi diba, the first step is to place piston 1 at compression stroke. in this way, you can now adjust I/E of piston 4, I of piston 3, and E of piston 2.
- Now, how do I turn the crankshaft to place piston 4 at compression?
- Is there a special tool to turn the crankshaft into place?
