6A-22 ENGINE MECHANICAL (G10, 1-CAM 6-VALVES ENGINE)
Valve Springs
Referring to data given below, check to be sure that each spring
is in sound condition, free of any evidence of breakage or weak-
ening. Remember, weakened valve springs can cause chatter,
not to mention possibility of reducing power output due to gas
leakage caused by decreased seating pressure.

Spring squareness:
Use a square and surface plate to check each spring for square-
ness in terms of clearance between end of valve spring and
square. Valve spring found to exhibit a larger clearance than limit
must be replaced.
