2000 TOYOTA CAMRY oil pressure

5. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT: Always use a fully charged battery to obtain
engine speed of 250 rpm or more.
(d) Repeat steps
(a) through
(c) for each cylinder.
NOTICE: This measurement must be done in as short a
time as possible.
Compression pressure:
1,226 kPa (12.5 kgf/cm
. 178 psi) or more
Minimum pressure:
981 kPa (10.0 kgf/cm
, 142 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
. 14 psi) or less
COMPRESSION CHECK
HINT: If there is lack of power, excessive oil consump±
tion or poor fuel economy, measure the compression
pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating
temperature.
2. DISCONNECT DISTRIBUTOR CONNECTOR(S)
3. DISCONNECT HIGH ±TENSION CORDS FROM
SPARK PLUGS
Disconnect the high ± tension cords at the rubber
boot.
DO NOT pull on the cords.
NOTICE: Pulling on or bending the cords may damage the
conductor inside.
4. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the spark plug.

(e) If the cylinder compression in one or more cylinders is
low, pour a small amount of engine oil into the cylin±
der through the spark plug hole and repeat steps (a)
through
(c) for cylinders with low compression.
wIf adding oil helps the compression, chances are
that the piston rings and/or cylinder bore are
worn or damaged.
wIf pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
6. REINSTALL SPARK PLUGS
Using a 16 mm plug wrench, install the spark plug.
Torque: 18 N±m (180 kgf±cm, 13 ft±lbf)
7. RECONNECT HIGH±TENSION CORDS TO SPARK
PLUGS
8. RECONNECT DISTRIBUTOR CONNECTOR(S)

CYLINDER HEAD COMPONENTS
INSPECTION, CLEANING AND REPAIR
1. CLEAN TOP SURFACES OF PISTONS AND
CYLINDER BLOCK
(a) Turn the crankshaft, and bring each piston to top dead
center (TDC). Using a gasket scraper, remove all the
carbon from the piston top surface.
(b) Using a gasket scraper, remove all the gasket material
from the cylinder block surface.
(c) Using compressed air, blow carbon and oil from the
bolt holes.
CAUTION: Protect your eyes when using high pressure
compressed air.
2. CLEAN CYLINDER HEAD
A. Remove gasket material
Using a gasket scraper, remove all the gasket material
from the cylinder block contact surface.
NOTICE: Be careful not to scratch the cylinder block
contact surface.
B. Clean combustion chambers
Using a wire brush, remove all the carbon from the
combustion chambers.
NOTICE: Be careful not to scratch the cylinder block
contact surface.
(c) Using needle±nose pliers, remove the oil seal.
