Please don't drive your vehicle until the timing belt is replaced. Its overdue by 15k miles.
I'll explain some of the questions for you.
1. Provent or Racor CCV filtration?
The crankcase ventilation system blows air that is full of oil mist. The oil mist mixes with sooty EGR exhaust gasses causing intake crud buildup and also pools in your intercooler reducing its efficiency A CCV filter removes the oil from the intake eliminating the associated issues.
2. Assuming you don't have SEGR or GDE tune to eliminate EGR
A very brilliant CRD owner developed a device (actually a kit you build yourself) caled a SEGR that disables the EGR without setting off a checkengine light. Green diesel engineering has custom tunes for the CRD which reduces the EGR cycle reducing future failure.
3. Do you have a lift pump? A modern diesel engine should have a lift pump. Jeep got cheap and didn't install one. A lift pump greatly improves start performance and should in theory prolong lifespan of the CP3 pump.
4. New or original fuel head? Stock fuel head is dangerous. It can leak fuel causing fires, it often sucks air causing hart starts. I have a racor fuel head which is a perfect fit. A new OEM replacement fuel head solves the earlier problem.
5. Has it had F37 neuter? To save on warranty costs, the F37 tune reprograms the engine ECU so it outputs less torque and power and modifies the transmission shift points to preserve the weak and crappy torque convertor.
6. Stock TC? See above, stock torque converter is a failure waiting to happen. New European TC seems to be good replacement and the ultimate TC is from suncoast but its pricey.
7. Any oil leaks? Some CRDs leak oil from the integrated valve cover gasket and some others have turbo lines that weep.
8. Has turbo ever been replaced? Failures are starting to show up in folks who don't do mandatory turbo cooldown.
9. Do you do turbo cooldown per owners manual? See above.
10. What is your OCI and did you use something else other than Mobil 1 0w-40? This recommended oil is not rated for use in our engine. Its an old spec oil that is only recommended by jeep to make cafe standards/fuel economy claims. Its not a good diesel oil.
11. WHO REPLACED THE TIMING BELT AT 100K AND WHAT OTHER ITEMS WERE REPLACED? Timing belt is overdue and along with it, rollers, tensionrs, and water pump should be replaced at every 100k. Engine destruction will occur (CRD is an interference engine) if it breaks which is what may happen if you keep driving it on borrowed time.
12. Were diff fluids replaced every 13-15k as suggested by FSM and owners manual? Service schedule is a little excessive. Rear diff fluid sees most wear and front/center diffs can easily go twice as far as long as you don't drive in 4wd each day.
13. Recall done on ball joints? Safety issue, extra weight of crd ENGINE hard on suspension/steering components.
14. Any use of fuel additives to improve lubricity? High Pressure Fuel Pump lasts longer when small amount of biodiesel, low ash 2 stroke oil, or lubricity additivies are used regularly.
Absolutely. I said it before and I will say it again. You can't hide here. Knowledgable people will ask questions here and the cheapskate/offloader owner can't hide behind feebay's decision to only allow the seller to selectively post questions the seller is willing to answer; CL failure to allow any questions or a dealer's "puffing" combined with the contract "as is" sale. That is not to say that this particular owner is a cheapskate/offloader, because as in life --- you have the right to remain silent, so long as you can handle the pain . Good luck on ebay.From the looks of the changed original post we are looking at someone who might have been trying to offload this particular vehicle short of doing all of the maintenance required for this particular vehicle.
Please do not let the dealer do the timing belt. Btw, no one has said anything about you. The conversation is on whether the vehicle has been maintained properly or not --- that goes to what the vehicle is worth. That is the only reason the questions were asked. You stressed the relative rarity of your vehicle --- okay, the next question is has it been properly serviced. If so, it is worth a premium --- if not, well that affects price. Thats about it --- not about whether you are a good person or not.You're free to say whatever you want about me, the internet makes that easy.
I did just flat out forget about the timing belt, so it's being replaced next week. The regular maintenance stuff has all been done. Those things are easy to remember since they are "regular" and not once every 100k miles.
Most of the other add-on stuff he was talking about I've never heard of. That seems to make me not up to par around here. *shrug* You guys just seem to work on your cars way more than I do.
