All components or measurements that are found to be outside the specification need to be documented
with pictures and submitted for authorization via a PuMA TeileClearing Hotline case and wait for a
response. Weekend and holiday submissions must wait for a response on the following business day
before starting any repairs.
Vehicles that require an oil consumption test, have passed the oil consumption test or do not require any
repairs do not need authorization.
Engine Repairs and Replacements:
Replacement engine assemblies are NOT pre-filled with engine oil.
After replacing an engine with a new or remanufactured engine assembly, the engine oil level must be
verified as outlined in the procedure below first, before starting the engine for the first time.
If the replacement engine is started to determine electronically if the engine is filled with the appropriate
amount of engine oil, damage to the replacement engine can occur immediately.
The engine may have some residual engine oil from assembly, but this is not enough engine oil to properly
lubricate the engine to measure the engine oil level electronically when it is started for the first time.
15
B01_21_18_N63_Oil_Consumption_Instructions
December 2018
Further, the electronic engine oil measurement is only operational when the engine is running at its full
operating temperature. Checking the engine oil without the engine running at operating temperature will lead to
an incorrect or incomplete measurement.
After replacing the engine or making engine repairs that require the replacement or removal of the engine
bearings, VANOS gears, camshafts, bed plate resealing, engine oil pump, engine oil filter housing, cylinder
head, engine oil cooler or anything that interrupts the engine oil supply circuit of the engine requires a short oil
pump and oil supply circuit priming procedure.
Refer to SI B11 09 15 for the detailed bleeding procedure.
After engine repair or replacement, pay attention to a proper installation of all engine ground
connections.
In particular, follow the recommendations from SI B12 24 14 (N63: Proper Ignition Harness Installation and
Ground Connections) for the ignition harness grounding. Any consequential damage to DME, alternator, or
QLT sensor resulted from a loose ground (causing BSD communication faults), is not covered under N63
Class Settlement.

1. Start the vehicle and allow it to reach operating temperature, approximately 15 minutes or less.
2. Quickly push-and-release the accelerator
pedal from idle position to between 2,000
and 3,000 RPM, then immediately allow
the engine to return to idle and observe
the exhaust tail pipes for smoke.
If smoke is present continue to step 3.
If smoke is NOT present then refer to the
“N63 Oil Consumption Instructions”
attached to SI B01 21 18.
IMPORTANT!
• If the vehicle is
smoking from the
exhaust then a clear
picture of the smoke
must be submitted with
the PuMA TeileClearing
Hotline case.
3. Inspect or measure the following 5 items in order. Note the inspection results on the attached “N63
Smoke Checklist.”
•
•
•
•
•
Engine front cover
Engine upper oil pan
Lower bell housing/cylinder heads valley area
Perform the timing chain test plan
Perform a compression test
IMPORTANT!
• If the engine is leaking engine oil, the oil leak must be an
active major engine oil leak, not seepage or wetness.
All components or measurements that are found to be outside the specification need to be documented
with pictures and submitted for authorization via a PuMA TeileClearing Hotline case at the end of this
procedure.
Vehicles that are not smoking or do not require any repairs do not need authorization.

GENERAL NOTES REGARDING ENGINE OIL LEAKS:
“Oil Leaks” are being defined as clearly visible oil presence (like oil drops) at the engine
components (e.g. area of oil pan, front cover, etc.), and in their vicinity. Also, large visible oil
stains (or oil accumulation) on the underbody panels are indication of oil leaks, causing a
substantial oil capacity loss.
The black (dirt stained) “wetness” marks on the engine components, DO NOT qualify as oil leaks.
4. Inspect the front engine cover for engine oil leakage.
Front cover is not leaking. Go to step 5.
Front cover is leaking. Go to step 7.
5. Inspect the upper engine oil pan for engine oil leakage.
The upper engine oil pan is not leaking.

Preparing for the inspection:
Bore scope specifications:
The recommended diameter of the fiber
optic cable (imager) should not be
greater than 5.5 mm. The 8 mm fiber
optic cable (imager) will work but it is
very tight and damage may occur to the
larger cable and imager.
The recommended borescope and
imager can be found at

If engine oil is found in the valley area, then the root cause of the engine oil
leak resides in the components on top of the engine i.e. turbocharger oil lines
cover, turbo charger, etc. Further basic diagnosis will be needed to find the
root cause this engine oil leak. Do not remove the transmission from the
vehicle. Go to Step 8.
If NO engine oil residue is found at the engine valley drain hole, but an
original visual inspection indicated leak in the bell housing area, the root
cause of the engine leak resides in the rear main seal and rear engine cover.
Do not remove transmission from the vehicle. Go to step 8.
If NO engine oil residue is found at the engine valley drain hole, then the root
cause of the engine oil leak will be related to the original visual inspection of
front cover, or oil pan. Go to step 12.
Using the borescope, provide a picture of the engine valley drain hole
regardless if oil is present or not.

7. Select “ABL Compression test”
8. Follow the test plan steps to complete the compression tests.
For reference the compression test procedure instructions can also be found in Repair Instruction 11 00 039
“Checking compression of all cylinders”
For the compression test procedure instructions refer to Repair Instruction 11 00 039 “Checking compression
of all cylinders”
The compression test should be performed after the engine has reached operating temperature. When
performing the test count the rotations of the engine crankshaft and apply the same rotations to each cylinder
compression test. The industry standard is 4 rotations per cylinder.
When comparing the values of all cylinders the compression results should not vary by more than 2.5 bar or
36.25 psi. If the difference is greater than 2.5 bar or 36.25 psi then proceed to step 14.
The test plan will record the measurements but you will have to determine if they are within specification or not.
If the BMW special tools are not available at the dealer then a manual gauge procedure can be substituted,
record all values in the oil consumption checklist. Use the limit values listed above to determine if the values
are within specification.
If the engine passes the compression test then proceed to step 10.
10. Inspect the turbochargers for engine oil leakage.
The turbocharger is OK.
No engine oil can be seen around the
turbocharger impeller.

Refer to SI B04 15 15 for additional ordering
information.
NOTE:
Prior to proceeding with VANOS units removal, and
after removing the valve covers, make sure that the
timing chain guides are intact (not broken).
Specifically, turn the engine manually 2-3 times over,
while listening for any unusual noises coming from the
timing chains area.
Using boroscope, run the probe down the chains on
both banks, to inspect for possible guides
breakage/cracks.
If any chains guides damage is found, supplement
your PuMA TC case with additional information and
pictures, and wait for response before proceeding
further.
Replace the cylinder head cover oil separators as per
Repair Instruction 11 15 140 “ Replace oil separator”
If the turbocharger inspection is “not OK” then replace
the turbochargers. Refer to repair instruction 11 65 025
