  2.  At each of several locations on bottom surface of cylinder head, measure distortion in six directions using suitable tools (A, B).

Cylinder head distortion

Limit : Refer to EM-118, "Cylinder Head"

VALVE DIMENSIONS

  1.  Check dimensions of each valve. Refer to EM-118, "Cylinder Head".
  2.  If dimensions are out of the standard, replace valve and check valve seat contact.

VALVE SEAT CONTACT

NOTE: After confirming that the dimensions of valve guides and valves are within specifications, perform this procedure:

  1.  Apply prussian blue (or white lead) onto contacting surface of valve seat to check the condition of the vavle contact on the seat surface.
  2.  Ensure that the contact area band is continuous all around the circumference.

Valve seat contact

(A) : OK
(B) : NG

  1. If the contact area is not continuous, grind to adjust valve fitting and check again. If the contacting surface still has NG conditions even after the re-check, replace the valve seat.

VALVE GUIDE CLEARANCE

  1. Measure diameter of valve stem using suitable tool (A) as shown.

Standard : Refer to EM-118, "Cylinder Head"

  1. Measure inner diameter of valve guide using suitable tool.

Standard : Refer to EM-118, "Cylinder Head"

  1. Valve guide clearance = (Valve guide inner diameter) - (Valve stem diameter)

Standard and Limit : Refer to EM-118, "Cylinder Head"

  1. If the calculated value exceeds the limit, replace valve and/or valve guide. When valve guide must be replaced. Refer to EM-56, "Disassembly and Assembly"

Valve guide clearance

VALVE SPRING SQUARENESS

CAUTION: Do not remove the valve spring seat from the valve spring

  1.  Set a try square (A) along the side of valve spring and rotate spring. Measure the maximum clearance between the top of spring and try square.

Valve spring squareness

(B) : Contact

Limit : Refer to EM-118, "Cylinder Head".

  1. If the valve spring exceeds the limit, replace the valve spring with the valve spring seat.

VALVE SPRING PRESSURE LOAD

CAUTION: Do not remove the valve spring seat.

  1.  Check valve spring pressure with valve spring seat installed at the specified spring height.

Valve spring pressure load

Standard : Refer to EM-118, "Cylinder Head".

  1. If the installation load or load with valve open is out of the standard, replace valve spring with valve spring seat.

INSPECTION AFTER INSTALLATION

Inspection for Leaks

  1.  Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to LU-8, "Refilling".
  2.  Use the following steps to check for fuel leaks.
  1.  Turn ignition switch "ON" (with engine stopped).
  2.  With fuel pressure applied to fuel piping, check for fuel leaks at connection points.
  3. Start engine.
  4.  With engine speed increased, check again for fuel leaks at connection points.
  1.  Run engine to check for unusual noise and vibration.

    NOTE: If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.

  2.  Warm up engine thoroughly to check there are no fuel leaks, exhaust gas leaks, or any oil/fluid leaks including engine oil and engine coolant.
  3.  Bleed air from lines and hoses of applicable lines, such as in cooling system.
  4.  After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.
