#11251 of 11441 Stock 2005 CRD, what mods are recommended?
Sep 07, 2011 (7:23 am)
I have a 2005 CRD with absolutely no mods to it. Had many CRD issues, 2 turbos, one computer, , 2 mass flow sensors, 2 EGR (once cleaned, second time replaced) and the transmission has been in 4 times at the dealer with multiple problems. I am now out of warranty and would like to know all the "life-prolonging" mods that I can do to it. I am thinking of the add-on micron oil filter, and I heard of a EGR bypass hose? Anything available for the transmission? Let me know what mods this forum suggests for longer life expectancy of the motor and tranny. Oh, yeah AC pump, tires, brakes, rotors, fan resistor issues don't count as those are normal issues with any car! I am only worried about the engine and transmission. This series of Liberty models, (without going Jeepster) is the last of the good SUV off-roaders. The new Jeep Liberty has lost its off-road capability from basic geometry and clearance changes to the model. I can't stand AWD, and Jeep's 4WD I have found to be the best for snow and fire-trails.

What is the GDE ecotune and where do I get one?. Also, what are the options for the EGR? I want to help my engine live longer and with less maintenance!.

#11255 of 11441 Original ccv vs Provent
Sep 17, 2011 (8:36 am)
I finally took everything off the top of the engine to inspect and discover what caused the large stains my truck leaves on the asphalt after a sustained effort
The original ccv valve is a robust 2" plastic disc kept closed by a light spring. It can not leak outside the engine and will retain a minimal overpressure in the crankcase until vacuum is applied by the turbo intake.
The Provent 200 that I never installed separates the oil by capillary effect (filter media). As of today, I can't evaluate its beneficial effect on my 'de-rated' 150 HP engine.
The stains under the truck were produced by a diesel fuel pond accumulating on top of the engine, where the injectors penetrate into the head. This 'fuel pond' emptied itself slowly when the truck was parked and kept the engine and tranny shining clean
The fuel lines feeding the 4 injectors were loose on the injectors, but not on the common rail. I used a flat 17mm crowfoot / flare wrench to slacken then torque the 8 nuts to approx 20N.M after removing the waste fuel rubber recuperation tube held by a wire spring clip above each injector. This took care of the fuel smell and stains; my fingernails took 5 days to recover their normal aspect

GRD or Green Diesel engineering eco tune. I think they have 3 levels of tuning. The Eco Tune is the lowest power and torque, but it is the one to get unless you have upgraded to a heavy duty torque convertor. I have the eco tune. www.greendieselengineering.com ($450, you send them your computer they program it and return it, if later you want to up-grade to a more powerful tune it is $50)
The EGR is a smog control device that gums up the engine. A provent 200 Is a must have, ($160), many people have made their own versions very cheaply, I got one on EBAY for a decent price and it is a clean set-up as compared to the home made versions and I plan on keeping my jeep many years, so, I sprang for it.
The Provent traps all the gunk that will eventually cause your turbo to fail. It also keeps your EGR valve clean.
Without the GRD tune, a Provent will trigger a check engine light, part of the GRD tune tells the computer to ignore the EGR yet keeps all the other protective functions. So, no check engine light on all the time.
The GRD did give me noticably more power, however I did not notice any significant increase in MPG as they claim, my overhead MPG reading is 4 MPG too high and my speedometer is 4MPH fast. In reality I get 23-24 MPG in town and 28-30 on the freeway. With the best MPG at around 70-73 MPH.
If you do not have to deal with Smog inspections, Stan in CA. did this Air filter modification using a Fram CA 8038 filter (I am in the process of doing this to mine.) http://liberty.eurekaboy.com/airintake3.jpg

FOUND IT!!!! The manufacturere says right side of engine, above starter.... YEAH RIGHT!!!! You need to dissasemble 1/2 the engine to see it. Easier, a mechanic here in Argentina fooound it under rust, on the lower right forward part of the engine At the bottom of the engine block where the oil pan starts. Wire brush away rust and number should be visible. Thanks for all the help.

Thank you for the excellent description and advice. I searched Ebay for "Provident 200" and found 3 different parts described. Is it the Mann Proivdent 200" Kit? My light comes on an off, often will go out when I add a diesel fuel conditiner. Even with the light on the vehicle seems to ru perfect. Any more info you can supply would be great

Hello caribou1 ! This is old "farout" the former sufferer of the "Green Beast" I try and check out this crd fourm every once and a while. So far as I can tell you seem to be the number one on keeping your CRD going by your self. I could never have done it. I am disabled and limited on doing the mechanical stuff. However I wish I were able.
Correct me but it seem that the CRD's in the US are so heavy with this smog equipment, and it really slows them down and repair is more often because of it.
My Chrysler Pacifica has 176,025 kilometers on it. I checked it on km because it has a electronic button that changes mph into kmph. I expect by this weekends it will have 110,000 on it. We put a lot of miles on going back and forth to the VA hospital clinics. I am soooo glad we got the LifeTime Powertrain warranty with the Pac. We also bought the LifeTime extended warranty as well. We have had a couple of problems, but mothing super major.
With Fiat it seems the vehicles are looking much better and they have improved a lot. the new 3.6 V-6 is a real fast engine, how well it is only time will tell.
I will say by and be looking for you from time to time.
