#10690 of 11454 2005 Jeep Liberty CRD Fuel Filter
Nov 24, 2009 (2:14 pm)
I started changing my own Water Separator/Fuel Filters a year or so ago when my wife filled my CRD's tank with E-85 instead of Diesel! I posted a pretty detailed description of that job on this forum. As for the filter & WIF sensor, I tried to remove it as specified in the Jeep Factory Service Manual and it was too difficult from below. I ended up taking off the fuel hoses and clearing the area around the filter. Then I put a oil filter wrench (scissors type) on the housing and spun it loose from the engine compartment. I spilled a little fuel when removing the old filter but it was no big deal. I think 30 to 45 minutes is about right for the filter change but I did not remove the housing from the fire wall, just hoses and the filter cannister/WIF sensor.

Thanks for the answers.
I use my block heater. In cold Northern weather, I've found the diesel to be so sluggish that I feel I'm a hazard on the road otherwise. The engine warms up much faster and a side benefit is that there is near immediate heating and defrosting.

I stopped using formulations like Mobil 1 5W-40 diesel because of the CI-4+ rating, namely too much ash. I find that CJ rated oils do the trick being sufficiently low in ash that the EGR issue goes away.
As to the block heater, I started using it last year and enjoyed having heat nearly instantly after starting my CRD.
#10693 of 11454 Which OBD scanner should I purchase
Nov 26, 2009 (12:58 pm)
Recently my CRD threw a code, P1263 when viewed from the odometer. As it turns out, it was wrong as the number two glow plug had failed (P0672) and was replaced under warranty. The tech at the dealer told me not to trust the codes that can be made to appear at the odometer and that a scan tool is the way to go. I asked the tech for some suggestions as to which tool to purchase and he had none to offer.
Has anyone found a good scan tool that works correctly with the CRD? Suggestions and thoughts welcome.

Winter,what oil do you recommend that can be bought in a Parts store or Walmart

How often will you really need to use the OBDII_Euro scan tool? After six years of ownership and 100,000 miles I haven't yet had to use it.

Well, that is a good question. I am starting to throw codes a bit more frequently as the Jeep ages, and this is bothersome to me, thus the request for information. Also, the codes that appear on the odometer are proving to be unreliable.

Walmart carries many items and then inconsistently. If I had to buy my oil at Walmart, then the Shell Rotella 5W-40, with the proviso it is CJ rated, would be my first choice, but then again I avoid Walmart like the plague.
I suggest and oil like Amsoil or RedLine. With Amsoil, you can become a "preferred customer" for a few dollars a year and buy their products at deal cost. My preference is Red Line as it has very low oil consumption and keeps everything squeaky clean. It costs more but then it is cheaper than a new engine.
#10698 of 11454 Oil consumption issue
Nov 30, 2009 (5:16 pm)
This evening I received a call from another 2005 Jeep Liberty CRD owner who uses the same dealer I use. The dealer asked me to speak with this fellow.
In our discussion I learned the following.
1. His CRD has about 74K miles on it. He purchased it new and has been using the Mobil 1 0W-40 oil. Oil change interval is 6250 miles.
2. Up to about a year ago, oil consumption was not an issue and he told me took a 6000 mile cross country trip without a problem.
3. Oil consumption is about 500 miles/quart. There is no external oil leak.
4. On start up, there is a little white smoke but no blue smoke. There is no blue smoke that is visible when driven.
5. He does a "nose" blowing every second or third day and gets a significant amount of black soot coming out of the exhaust each time. For about one year most of his driving is stop and go city.
6. He uses the cheapest fuel he can find, a no name brand which I avoid. He does not use any fuel additives.
7. States has good power at all times.
I suggested that he stop using the Mobil 1 and try either Shell Rotella 5W-40, RedLine or Amsoil. Also suggested he put some decent additive in the fuel to clean out the fuel system and combustion chambers.
I am of the opinion that there are several places to look here.
1. Turbocharger is starting to fail.
2. Bad valve seals or bad valve guides
3. Warn piston rings, a broken piston ring(s) or carbon loaded rings.
4. Oil being pulled into the engine by some other route that I have not thought of.
Any input/ideas welcome.
As always, thank you.

You might check the crankcase ventilation valve. If that fails I could see the turbo really sucking oil.
