I know this is about fuel filters but here is a TSB on oil filters for the 24 valve engine for those that have not seen it.
Date: May 18, 2001
Models: 1989 -1993 (AD), 1994 - 2001 (BR/BE) Ram Truck
NOTE: THIS BULLETIN INVOLVES 1989 - 201 MY 2500 AND 3500 RAM TRUCKS EQUIPPED WITH A 5. 9L CUMMINS DIESEL ENGINE.
Discussion:
Customer may complain of high oil consumption, grey oil smoke coming out of the exhaust or breather tube, or mechanical knocking. Neoprene compounds used internally in the manufacture of oil filters not recommended by DaimlerChrysler may separate from the filter, lodge in the piston cooling nozzle, and can fail the engine.
NOTE: THIS IS NOT AN ENGINE DEFECT.
(See the table below for a list of filters recommended by DaimlerChrysler for use with the 5. 9L Cummins diesel engine. )
NOTE: SECTION 2. 7 OF THE TRUCK WARRANTY MANUAL STATES DAIMLERCHRYSLER MOTORS CORPORATION IS NOT RESPONSIBLE FOR FAILURES RESULTING FROM IMPROPER REPAIR OR THE USE OF PARTS WHICH ARE NOT GENUINE DAIMLERCHRYSLER MOTORS CORPORATION / MOPAR OR DAIMLERCHRYSLER MOTORS CORPORATION / MOPAR APPROVED PARTS. DAMAGES CAUSED BY THE USE OF OIL FILTER NOT APPROVED BY DAIMLERCHRYSLER MAY NOT BE COVERED BY THE NEW VEHICLE WARRANTY. DAIMLERCHRYSLER RECOMMENDS THE FOLLOWING OIL FILTERS. DO NOT USE ANY OIL FILTER CONTAINING NEOPRENE. PLEASE SHARE THIS WITH YOUR CUSTOMERS.
RECOMMENDED OIL FILTERS FOR USE WITH CUMMINS 5. 9L DIESEL ENGINE:
Part Number Manufacturer
05016547AC Mopar
LF3894 Fleetguard Stratopore
LF3552 Fleetguard Microglass
LF3949 Fleetguard Cellulose
3937695 Cummins Cellulose
FL896 MotorCraft Cellulose
L45335 Purolator Cellulose
PF1070 AC Delco Cellulose
Policy: Information Only
Notes:
The LF3349 Cellulose filter does not appear on this list. It was approved in the past for 12Valve engines, but it has been superseded by the LF3949, which has a stronger metal case for the 24 Valve engines. You can use your existing LF3349's for 12 valve engines without concern about warranty coverage.
What does this TSB mean?
If you use one of the filters in this list, you will not have to worry about warranty coverage of an oil related engine failure. If you choose to use another filter that is not on the list, DC will (justifiably) make you pay for repairs if a piston cooling nozzle becomes clogged by a piece of filter material. Some filters have disintegrated resulting in severe engine damage. When this happens, you must seek compensation from the manufacturer of the filter (numerous reports of Fram failures have surfaced recently, and Wix filters damaged some 1st Gen engines back in the 90's). If the manufacturer is standing behind their product, they will pay for the repairs. GOOD LUCK! Is saving a few bucks on an oil filter really worth the risk of a $4000 repair bill? Your decision...
Not mentioned in the TSB, but a valid reason for denial of warranty coverage is damage caused by foreign material introduced into the oil filter by the person changing the oil. You can not expect a manufacturer to pay for engine damage caused by carelessness during an oil change, that kind of damage is not due to a manufacturing defect! Anything in the center of the filter goes directly into the oil galley when the engine is started. When you open an oil container and pre-fill the oil filter, be very careful that you do introduce into the center of the filter any of these into the filter:
dirt or debris from your hands or the work area
a bit of sealing foil from the top of the oil container
plastic shavings from the oil container
plastic or paper from the oil filter wrapping or container
