– Otherwise, add oil until its level is between
marks as required.
– To add oil, unscrew oil cap. Place a funnel into
the opening and add the recommended oil to
the proper level. Do not overfill.
ENGINE OIL PRESSURE TEST
NOTE: The engine pressure test should be done
with a warm engine and the recommended oil.
Use oil pressure gauge (P/N 529 035 709) and
hose adaptor (P/N 529 035 652) and install where
shown. A 1/8 NPT pipe extension may ease the
installation.
Remove oil pressure switch.

To prevent the EMS to go in limp home mode (at
2500 RPM) or to generate a fault code, start en-
gine, THEN ground OPS connector to engine.
You may find easier on supercharged engines to
removetheplugfromtheendofenginehead.
However, the pressure readings will be different.
Use the proper table below.
NOTE: The pressure may be measured from cylin-
der head on all 4-TEC engines if desired.
