ENGINE – SPECIAL TOOLS, ENGINE TUNING, CAMSHAFT, VALVE STEM SEAL11 - 4
Engine tuning
1. Checking revolutions when the engine is
idling
The standard revolutions for when the engine is idling have been
changed. Other servicing guidelines remain unchanged.
Standard revolutions: 800 ± 50 r/min
2. Checking compression pressure
The standard for compression pressure and the limit for
compression pressure have been changed. Other servicing
guidelines remain unchanged.
Standard compression pressure: 1000 kPa – 250 r/min
Compression pressure limit: 650 kPa – 250r/min

Removal and fitting
Caution
1. If Brembo brake callipers are being used take care that they are not scratched by other components or tools
because there is a chance that the paint might peel off. In addition, if any brake fluid gets on the callipers, it
should be wiped off immediately.
2. Parts marked with * should be removed and then fitted for each cylinder in turn.
Jobs to be completed before removal and after fitting
• Removal and refitting of the undercover (Ref Section 51: Front bumper)
• Checking the tension of the drive belt (only after fitting)
• Draining and refilling of the coolant
• Removal and refitting of the air duct

Fitting the O-ring/oil feeder control valve
Caution
1. Do not re-use O-rings.
2. When fitting O-rings, first wind some non-adhesive tape
(seal tape etc) around the oil channel of the oil feeder
control valve, in order to prevent damage to the O-ring.
If the O-ring touches the oil it could start an oil leak.
1. Apply engine oil to the O-ring on the oil feeder control valve.
2. Fit the oil feeder control valve to the cylinder head.
3. Tighten the mounting bolts for the oil feeder control valve to the
specified torque.
Tightening torque: 11 ± 1 N•m

Removal guidelines



A 
Removing the cylinder head bolts
Use the special wrench for cylinder head bolts (MB991654) to turn
the bolts 2~3 times in order to loosen them, before removing them
in the numerical order as shown in the diagram.
Fitting guidelines



A 
Fitting the cylinder head gasket
1. Remove the gaskets which have been stuck onto the surface of
the gasket.
Caution
Do not allow any foreign matter to get into the channels for
coolant or oil, or into the cylinder.
2. Fit the cylinder head gasket to the cylinder head, so that the
holes in the cylinder head gasket match up with the holes in the
cylinder head.



B 
Fitting the cylinder head bolts
1. Check that the length of the body of cylinder head bolts is less
than the maximum permitted. If the length is in excess of the
maximum permitted, replace the bolt with a brand new one.
Maximum length (A): 99.4mm
2. Apply a small amount of engine oil to the screw thread of the
bolt, and to the washer.

ENGINE – TIMING BELT, TIMING BELT B, ENGINE ASSY11-28
5. Using the special wrench for the tensioner pulley socket
(MD998767) or a torque wrench, apply tension torque (3.5 N·m)
to the timing belt in the direction shown in the diagram, and
tighten the mounting bolt for the tensioner pulley to the specified
torque.
Tightening torque: 48 ± 5 N·m
Caution
When tightening the installed bolt, take care that the
tensioner pulley does not turn around with it. If the pulley
does turn around with the bolt, the tension of the belt will
become too strong.
6. Remove the wire or pin which had been inserted when the auto-
tensioner was fitted.
7. Remove by hand the special adjusting bolt (MD998738) which
had been fitted in step 1.
8. Turn the crankshaft two complete turns in a clockwise direction,
and leave it for about 15 minutes.
9. Reinsert the wire or pin which had been removed in step 6, and
check that it can be easily pulled out again.
If the wire or pin can be easily pulled out the tension of the
timing belt is just right, so the wire or pin should be removed
completely. At this point check that the auto-tensioner rod is not
projecting more than the amount specified.
Specified projection (A): 3.8 ~ 4.5 mm
10. If the wire or pin cannot be easily pulled out, repeat steps 1 to 8
until the tension of the timing belt is just right.
11.Recheck that the timing marks on all of the sprockets are in line.
Caution
If the crankshaft bolt is turned in an anti-clockwise
direction, the tightening torque of the crankshaft bolt must
be checked, and if it is loose, it must be retightened.

A 
Fitting the O-ring

pipe, and insert it into the water pump after moistening with water
the places where the O-ring will make contact with the water pump.
Caution
Ensure that absolutely no engine oil, or other type of grease,
gets onto the O-ring.
