This TSB is being republished in its entirety to include 1995
E-250/350 models.
ISSUE:
Some vehicles may exhibit a poor idle quality and/or low output
after the engine returns to idle speed. This may be caused by
a damaged oil pick-up tube assembly or a missing or damaged O-ring
seal on the oil pick-up tube causing high Injection Control
Pressures (ICPs).
ACTION:
If high ICPs are encountered, refer to the following Diagnostic
Procedure to determine the cause of the concern.
DIAGNOSTIC PROCEDURE
- Complete all the steps in the 1994-1/2 or
1995 DI Turbo Diesel Diagnostic Guide. Repair any problems
which may exist that are not ICP related before proceding with this
procedure.
- Verify the vehicle has oil with the
correct specification and the correct oil level. If the oil
quality or service interval is unknown, change the oil and fill with
oil of known specification. If the concern still exists,
continue with this procedure.
 |
CAUTION: |
BE SURE THE VEHICLE IS IN "PARK" OR "NEUTRAL"
WITH THE PARKING BRAKE APPLIED FOR THE REST OF THIS PROCEDURE. |
- While the engine is idling, note the ICP
reading on Rotunda New Generation Star (NGS) Tester (007-00500) or
the ICP voltage at the Breakout Box (014-00950 104-pin, 014-00322
60-pin).
- Accelerate the engine to 3300 rpm.
If the engine is unable to reach 3300 rpm, this is the result of
another failure. Repair this condition before proceding with
this procedure.
- ICP readings which increase above 1250
psi (1.75 volts) within 15 seconds may be caused by air being drawn
into the high pressure oil system.
- Add an additional 2.8 L (3 qt) of oil to
the crankcase (raising the oil level to 16 L (17 qt)).
- Raise the rear axle of the vehicle so the
rear tires are approximately 10" off the ground to fully submerge
the pickup tube.
- Accelerate the engine to 3300 rpm and
monitor the ICP readings or ICP voltage. If the ICP readings
now stay below 1250 psi (1.75 volts), then there is a failure of the
oil pick-up tube assembly.
- Reconnect the oil pan per the appropriate
Service Manual.
- Reconnect the oil pick-up tube and
inspect for damaged or missing O-ring. Inspect the tube
assembly for possible damage or cracks.
- Replace any defective parts as necessary.
- Fill the crankcase to the proper level
(13.2 L (14 qt)), and retest the system to verify the ICP readings
are now within specification.
