4. Apply liquid gasket without breaks to the specif ied location with the specified dimensions.
• If there is a groove for the liquid gasket application, apply liquid gasket to the groove.
• As for the bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.
• Within five minutes of liquid gasket application, install the mat-
ing component.
• If liquid gasket protrudes, wipe it off immediately.
• Do not retighten nuts or bolts after the installation.
• After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.

Precaution for Liquid Gasket
INFOID:0000000004305229
REMOVAL OF LIQUID GASKET SEALING • After removing nuts and bolts, separate the mating surface, using Tool and remove old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
• Tap Tool to insert it (1), and then slide it by tapping on the side (2)
as shown.
• In areas where Tool is difficult to use, use plastic hammer to lightly
tap the parts, to remove it.
CAUTION:
If for some unavoidable reason suitable tool such as screw-
driver is used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE 1. Remove old liquid gasket adhering to the liquid gasket applica- tion surface and the mating surface, using scraper.
• Remove liquid gasket completely from the groove of the liquid gasket application surface, bolts, and bolt holes.
2. Thoroughly clean the mating surfaces and remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to Tool.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-42, " Recommended Chemical Prod-
uct and Sealant " .
4. Apply liquid gasket without breaks to the spec ified location with the specified dimensions.
• If there is a groove for the liquid gasket application, apply liquid gasket to the groove.
• As for the bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.
• Within five minutes of liquid gasket application, install the mat-
ing component.
• If liquid gasket protrudes, wipe it off immediately.
• Do not retighten nuts or bolts after the installation.
• After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

• If dimensions are out of the standard, r eplace valve and check valve seat contact.
Valve Guide Clearance
Valve Stem Diameter
• Measure the diameter of valve stem with micrometer (A).
Valve Guide Inner Diameter
• Measure the inner diameter of valve guide with bore gauge.
Valve Guide Clearance
• (Valve guide clearance) = (Valve guide inner diameter) – (Valve
stem diameter)
• If the calculated value exceeds the limit, replace valve and/or valve guide.
Valve Seat Contact
• After confirming that the dimensi ons of valve guides and valves are
within the specifications, perform this procedure.
• Apply prussian blue (or white lead) onto contacting surface of valve seat to check the condition of the valve contact on the surface.
• Check if the contact area band is continuous all around the circum-
ference.
• If not, grind to adjust valve fitting and check again. If the contacting surface still has “NG” conditions even after the re-check, replace
valve seat. Refer to EM-82, " Disassembly and Assembly " .
