INSPECTIONM1151003100616
Check the following points; replace the part if a
problem is found.
Inlet Manifold Check
1. Check for damage or cracking of any part.2. Clogging of the negative pressure (vacuum) outlet
port, or clogging of the exhaust gas recirculation
passages.
3. Using a straight edge and feeler gauge, check for
distortion of the cylinder head installation surface.
Standard value: 0.15 mm or less
