Now what to do?. Chrysler will not help its a salvage title and I am the the 4 owner so I am on my own. The techs at the local dealer did not even know what they were looking at when I showed them the part and said the only way that could happen is to run it out of oil and it my fault. So i am going to do it all on my own. The OPDA is no problem for me to replace. But how about the Cam can it be done shade tree style by me. What all do i need to address and get for the swap?
I can only offer my advice. Take all the info in this thread and choose the level of response you feel comfortable with.

When I first discovered the problem I was panicked. I ran to the dealer so I had it documented. I paid them $100 to swap it out and was freaked out when I saw the shine on the camshaft gear. Fortunately for me, mine acted up and I got a replacement with no delay or complications.

Now that I've calmed down a bit, I've decided the camshaft doesn't look that bad. The problem is clearly with the binding and lack of oil causing the shaft to bind prematurely. I think this is mostly due to the missing oil groove in the 05-06 OPDA. There is documentation saying this is a wide spread problem and I don't disagree with that. There is information supporting high ZDDP helping (and being better for flat tappet) so changing to a higher ZDDP oil seems like the right way to go.

My long term plan is to get an oil groove cut in, and add a zerk.

Short term, I'm running a high mileage oil with more ZDDP than traditional oil.

I have no intention of replacing the camshaft gear or installing a HESCO pump.

The gears will wear. The distributor gear is the weak gear so it should wear "faster". FOG should have a write up on greasing the bushing. I'm of the opinion that if you can keep the shaft from binding you will be okay. I wouldn't recommend pulling apart the camshaft.

You need to read the code and see what the check engine light is telling you.

The way the computer is set up in the 05-06 is the computer won't let the engine start if its not getting a signal from the CPS sensor. Even if its WAY out of sync the computer will let you start the engine and drive it normally but will limit top engine speed to 2500RPM.

I've lost count how many times I've pulled my CPS testing oils, gears, ETC and never had a problem with the engine not running unless I forgot to plug the CPS sensor back to the engine wiring harness.

Its not a stock item and they will have to order it. But they keep it in local warehouses so its only like a day or two.

I have a box with about 5 gears (different brands, different oils, ETC) and the Napa Echlin with the Mobil One 5W-40 "turbo diesel truck" oil has shown me the best results in lack of wear.

it will go up to 2500 rpms but it is real rough and sometimes it will die it was running fine after the zerk was installed for about two weeks

My Story:

jeep wrangler 2005 rubicon with 57K miles. I took the jeep last friday to a mechanic so he could check the wear on the OPDA and it does have wear but it doesn't seem as bad as other pictures I've seen in this thread.
The camshaft is ok, but the mechanic told me that the wear on the OPDA is uneven ( I will try to explain it as I am mechanically handicapped) , meaning that he thinks that the problem is a poor quality produced camshaft that is apparently bent or it is not well strait so when it turns you can see on the OPDA that some of the wear is more on the bottom and as you turn the gear you can see some other wear on the top but it is never at the same distance between the top and bottom as you keep turning the gear.

Also, when he pulled it out that was plenty of oil all the way to the top of the OPDA gear, perhaps thinking that there is enough lubrication.

Does anyone believe that the HESCO pump will have some benefit? I am thinking on changing the OPDA because I am afraid it will get worse down the road and have it checked every 5K miles perhaps. Also I was thinking on changing the oil immediately to Mobile 1 10W40 high mileage and hope for the best

I don't know what else to do...
I guess it will take D/C some time to come up with a solution.

^^I don't think D/C is is losing sleep at night trying to come up with a solution. They've moved onto the JK's.

There isn't a magic replacement if that's what you're asking. They likely replaced it with the same kind of OPDA. The REV-B is not different from the REV-E, they are all prone to fail.

Since you haven't done anything for 94K miles, I would guess you are due. If you are concerned pull it for some reassurance. Odds are it is worn. I can't say for certain every '05-06 will fail, there is just a higher likelihood.

I asked them..."you are charging me 79.00 to watch gas shoot out of my gas tank?" Then the service manager walked up and said..."your jeep is out of warranty, I dont' know what to tell you. You had the option to buy an extended warranty when you bought it." Seriously? You're going to say that to me? There are TSB's out on both of these issues and you're going to treat me like this? Ridiculous

Just got off the phone with Chrysler customer service. The lady said there were no TSB's related to my vin number and if any parts were determined to need replacement while it was at the dealership, I would have to cover all costs up front and then send in my receipts and a copies of everything to get some "assistance" from Chrysler. I mentioned to her about the 100 dollar deductible that some of you were talking about in earlier posts and she is saying that is only for vehicles still under warranty. Ok...so I need some help...what is my next step to get this issue taken care of?
My jeep was not under warranty or included in any recall or tsb. I told the lady at chrysler that's why I was calling her, because it wasn't and it should have been. I was not going to take no for an answer. I would keep calling them.

I just replaced mine yesterday. I got a new assembly from the dealer (175 dollars)
Mine was ticking quite loud and was getting annoying. I did not have starting trouble or squealing or oil pressure problems...just TICKING/tapping from the rotation in the housing.

I carefully marked the position of the assembly on the engine block so that the new one would be facing in the same direction. I then took careful note of the rotational position of the disc inside the housing of the old unit so that I could match that rotation position in the new unit. The disc inside has notches on it in sequence. One notch, two notches, three, ect in a pattern. I rotated the new disc until it was in the same rotational position.

It took a few tries to get the unit to slide in at the correct orientation. As the assembly slides in and seats in the gear the gear will turn into position. You have to kind of over-rotate the unit upon initial placement so that it will rotate into correct position.

After a few ins and outs it lined up perfectly. Started it up...perfect timing, NO TICKING! Good to go!
