  1. Clogged filters will cause the oil bypass valve to open and unfiltered oil will lube the engine. It is the disintegration of the inner oil filter seals that will clog piston cooling jets that destroy the engine.
  2. Thank you! One would be a complete idiot to use a sub standard oil or fuel filter in a $ 70,000.00 plus truck powered by a diesel or gasoline engine. OEM is always the best way to go unless it has been absolutely 100% proven that an aftermarket filter is superior. Hey, it’s your truck and your money, play at your own risk. Always find it amusing where someone destroys their engine, wether by abuse, using wrong oil or filter, then switch back over to the OEM filter trying to dupe the dealer and the factory to cover it under warranty. Everyone wants to delete what they don’t understand and install fueling devices, cheat boxes, downloads, larger injectors, turbos and straight pipe exhaust to make more power, thus destroying their transmission and expect the factory to cover their tampering with a warranty. It doesn’t matter what you drive, ride or fly, if you cheap up on the parts, modify the engine to increase it’s rated power output or skip on required maintenance the engine or transmission will fail. I don’t care whose Diesel engine you believe is best or superior. Just for the record Cummins has been around many more years than Duramax, Isuzu, Powerstroke, Toyota, Volvo Penta, Mitsubishi, Nissan, Kubota, CAT, Benz, VW, etc. Choose your poison as they all work under the same scientific theory on internal combustion. You can only blame the person in the mirror and no one else. You are your own warranty station and I do hope you are smarter than the engineers who designed your truck. If not, they will gladly sell you another one. Cheers !!
  3. TSB 09-004-01 Approved Diesel Engine Oil Filters 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 Thanks to TDR forum's Jim and Bob Bergevin for supplying this TSB information
  4. I’m certain a google search will locate itCummins Cumberland in Louisville , Kentucky has an interesting display of cutaway oil filters in their parts showroom. All the major brands, even Baldwin, and Wix. Just a cursory glance at the insides is enough to make you glad you're using Fleetguard or Amsoil filters. As most people in these forums know, I've lost two engines to Fram filters, one a Dodge 318, the other a high performance engine. In both cases, the filter media came apart and clogged the oil pickup tube in the pan. That was 15 years ago, I've never bought another Fram. Warranty? Hahaha. Yeah right. Cheaper to get a new engine, than take them to court. This was taken from Turbo Diesel Register. The Dodge truck magazine for Cummins
  5. The best filters are those which are OEM and engineered for your particular engine. As far as the aftermarket, I have had good service from Hastings and AMSOIL filters. Cummins engines has issued bulletins not to use Fram oil filters on their engines as the internal seals on the filter fall apart and plug up the piston cooling jets. Blow a Cummins with a Fram filter and your warranty is void !!! Stated in the their bulletin. Better to be safe than sorry, always go with the GM filters !! May I add that a replacement engine could very well cost with labor, upwards of $ 35,000, why would anyone play games with cheap filters?
  6. I am certain this can be addressed with TCM download when the factory releases it to the dealer
  7. Drove one yesterday and the 10 L 1000 shifted silky smooth. Truck had a July build date.
  8. Interesting to see if the 7.3 Ford can hang on to it’s spark plugs, maybe so tight that it won’t let them be removed in one piece.
  9. I believe what you are experiencing on the slow down is due to the 3.73 gears in the differential where as the 2020 is equipped with 3.42 gears. Big difference.
  10. The 6.6 gasser will out pull the 6.0 no doubt. Similar to comparing a small block to a big block. No replacement for displacement!!
