OIL RAIL AND INJECTOR
REMOVAL
Prior to removal, be sure to confirm and record the
group code of the injector installed using Tech2.
1. Disconnect battery ground cable.
2. Remove air cleaner cover and air duct.
3. Remove intercooler.
Refer to “Intercooler” in this manual.
4. Remove PCV hose and pipe.
5. Remove cylinder head noise insulator cover.
6. Remove high pressure oil pipe.
CAUTION:
1) Sleeve nut should be loosened with cloth tied
around it to prevent oil from spurting due to the
remaining pressure.
2) The high pressure pipe should be disconnected
with a cloth tied around the intake manifold
glow plug to prevent oil from flowing out of the
oil rail.7. Loosen eye bolt of fuel pipe at fuel pump side.
NOTE: Cloth should be put around the loosened eye
bolt to prevent fuel from flowing out.
8. Remove fuel return hose at chassis side.
9. Remove PCV hose to cylinder head cover.
10. Remove cylinder head cover.
11. Drain the oil from oil rail assembly.
12. Record the identification marking of injector for
each cylinder which is indicated on the upper
portion of injector.
There are nine kinds of identification marking
available, one alphabet letter and one numeral
letter.
In case three kinds of markings are given, one
alphabet letter (sometimes printed) and one
numeral letter, top priority is given to the one
alphabet letter and one numeral letter.

12. Immediately install high pressure oil pipe and
tighten to specified torque.
Torque: 80 Nꞏm (8.1 kgꞏm / 57.9 lb ft)
13. Install cylinder head noise insulator cover.
Refer to “Cylinder Head” in this manual.
14. Install intercooler assembly.
Refer to “Intercooler” in this manual.
15. Install air cleaner cover and air duct.
16. Use TECH2 to rewrite injector data to ECM.
For rewriting method refer to section “Data
Programming in Case of ECM Change” of 6E 4JX1
engine driveability and emissions in this manual.
NOTE:
1) On completion of servicing, bleed air from the
engine inside fuel passage by means of the priming
pump. (The priming pump should be operated more
times than in the case of conventional engines.)
2) As air is in the oil rail, it takes more time to start the
engine. Rough idling may occur while the air is
being bled completely after starting the engine, but
it does not indicate trouble.
The air will be bled and normal engine status will be
reached while the vehicle is driven for about 5 km
or engine is operated for about 5 minutes at 1500 to
2000 rpm.
3) The injector spare part will be provided for group
number B1, B2 and B3 only.
