• Flatness of gasketed surface :
Using a straightedge and thickness gauge, check surface at
a total of 6 locations. If distortion limit, given below, is
exceeded, correct gasketed surface with a surface plate and
abrasive paper of about #400 (Waterproof silicon carbide
abrasive paper) : place paper on and over surface plate, and
rub gasketed surface against paper to grind off high spots.
Should this fail to reduce thickness gauge readings to within
limit, replace cylinder head.
Leakage of combustion gases from this gasketed joint is
often due to warped gasketed surface : such leakage results
in reduced power output.
Cylinder head gasketed surface distortion limit
0.05 mm (0.002 in.)
• Distortion of manifold seating faces :
Check seating faces of cylinder head for manifolds, using
straightedge and thickness gauge, in order to determine
whether these faces should be corrected or cylinder head
replaced.
Manifold seating face distortion limit
0.10 mm (0.004 in.)
