Camshafts
Inspection
Loosen the adjusting screws.
Remove the camshaft holders and the rocker arms
NOTE: Mark the rocker arms before removing
them.
Reinstall the camshaft and holders. Tighten the
camshaft holder bolts in a crisscross pattern, begin-
ning with the inner bolts.
9.8 N.m (1.0 kgf.m,7.2 lbf.ft)
Seat the camshafts by pushing them toward the dis-
tributor end of the head with a screwdriver.
Zero the dial indicator against the end of the
camshaft. push the camshaft back and forth and
read the end play.
Camshalt End Play:
St.ndard lNow): 0.05 - 0.15 mm
(0.002 - 0.006 inl
Seivice Limit: 0.5 mm {0,02 in)
Remove the camshaft holder bolts from the cylinder
head.
NOTE: Unscrew the camshaft holder bolts two
turns at a time, in a crisscross pattern.
Lift the camshafts out ot the cylinder head. wipe
them clean, then inspect the lift ramps. Replace the
camshaft if any lobes are pitted, scored, or exces-
srvely worm
Clean the camshaft journal surfaces in the cylinder
head, then set the camshaft back in place. Insert a
plastigage strip across each iournal.
Install the camshaft holders and torque the bolts to
the values and in the sequence shown on page 6-30.
NOTE: Do not rotate camshafts during inspection.

11. lf camshaft-to-holder oil clearance is out of toler
ance:
. And the camshaft has already been replaced,
vou must replace the cylinder head.
. lf the camshaft has not been replaced, first check
total runout with the camshaft supported on V-
blocks.

- lf the total runout of the camshafts is within tol-
erance, replace the cylinder head.
- lf the total runout is out of tolerance, replace the
camshafts and recheck. lf the oil clearance is still
out of tolerance. replace the cylinder head.

Troubleshooting
Troubleshooting Guide
NOTE: Across each row in the chart. the systems that could be sources of a symptom are ranked in the order they should
be inspected staning with O. Find the symptom in the left column, read across to the most likely source. then refer
to the page listed at the top of that column. lf inspection shows the system is OK, try the next mosr likely system O, etc,
* lf codes other then those listed above are indicated, count the number of blinks again. It the MIL is in fact blinking
^ these codes, replace the ECM.
qy, lf the MIL is on while the engine is running. connect the SCS shon connector to the service check connector. It no
code is displayed {MlL stays on steady), the back-up system is in operation.
Substitute a known-good ECM and recheck. lf the indication goes away, replace the original ECM.

Troubleshooting
Self-diagnostic Procedures
When the Malfunction Indicator Lamp {MlL) has been reported on, do the following:
'1. Connect the SCS short connecto. to Service Check Connector as shown. (The 2P Service Check Connector is
located under the dash on the passenger side of the car.) Turn the ignition switch on.
DATA LII{KCONNECTOR (3PI
NOTE:Do not attachjumper wire.
2. Note the Diagnostic Trouble Code (DTC): The MIL indicates I code by the length 8nd numbsr ot blinks. The MIL
can indicate multiple component problems by blinking separate codes, one after another. Codes 1 through Igre
indicated by individual shon blinks. Codes 1O through 43 are indicated by a series of long and shon blinks. Th€
number of long blinks equals the first digit, the number ot short blinks equals the second digit. Sometimes the
firsr blink is difficult to see; always count the blinks at least twice to verify the code.

a lf codes other than those listed above are indicated, verifv the code. lf the code indicated is not listed above, replace

a The MIL may come on, indicating a system problem when, in fact, there is a poor or intermittent electricalconnection.
First, check the electrical connections, clean or repair connections it necessary.
o The MIL and @ indicator light may light simultaneously when the Diagnostic Trouble Code (DTC) 6, 7 or 17. Check
the PGM-Fl system according to the PGM-Fl system troubleshooting, then recheck the l!! indicator light. ll it lights,
see page 14-5O, 51.
a The MIL does not come on when there is a malfunction in the A/T Fl signal or Electrical Load Detector (ELDI circuits.
However, it will indicate the codes when the Service Check Connector is shorted.
