Replacement
1. Valve, Valve Seal, and Valve Spring Seat - Remove
2. Valve Guide - Remove
- As illustrated below, use a commercially available air-impact valve
guide driver (A)
modified to fit the diameter of the valve guides. In most cases, the same
procedure can be
done using the valve guide driver, 5.35 x 9.7 mm and a conventional hammer
- Select the proper replacement valve guides, and chill them in the
freezer section of a
refrigerator for at least an hour.
- Use a hot plate or an oven to evenly heat the cylinder head to 300ºF
(150ºC).
Monitor the temperature with a cooking thermometer. Do not get the cylinder
head
hotter than 300ºF (150ºC); excessive heat may loosen the valve seats.
- Working from the camshaft side, use the valve guide driver and an air
hammer to drive the
valve guide about 2 mm (0.08 in) towards the combustion chamber. This will
knock off some
of the carbon and make removal easier. Hold the air hammer directly in line
with the valve
guide to prevent damaging the driver. Wear safety goggles or a face shield
- Turn the cylinder head over, and drive the valve guide out toward the
camshaft side of the
cylinder head
- If a valve guide will not move, drill it out with an 8 mm (5/16 in)
drill bit, then try
again.
NOTE : Drill guides only in extreme cases; you could damage the
cylinder head if the valve guide breaks.
3. Valve Guide - Install
- Take out a new valve guide(s) from the freezer, one at a time, as you
need them
- Apply a thin coat of new engine oil to the outside of a new valve guide
- Install the valve guide from the camshaft side of the cylinder head; use
the valve guide
driver to drive the valve guide into the specified installed height (A) of
the valve guide
(B). If you have all 16 valve guides to do, you may have to reheat the
cylinder head.
18.25-18.75 mm (0.7185-0.7382 in)
- Coat both the valve guide reamer, 5.5 mm and the valve guide
with cutting oil
- Rotate the valve guide reamer clockwise the full length of the
valve guide bore
- Continue to rotate the valve guide reamer clockwise while
removing it from the bore
- Thoroughly wash the valve guide in detergent and water to
remove any cutting residue.
4. Valve Stem-to-Guide Clearance - Inspect
NOTE: Verify that a valve slides into the intake and exhaust valve guides
without sticking.
5. Valve Seat - Inspect
NOTE: If necessary renew the valve seat using a valve seat cutter.
6. All Removed Parts - Install
- Install the parts in the reverse order of removal.
