OK, so I skimmed some of this thread, and read all of page one. I have an 06LJ that I just bought used with 33k on it. It started having issues today, threw all kind of CPS codes, running rough, CEL...etc This happened as the mechanic finished installing my lift, the Jeep wouldn't start, when it did it ran rough, and anything over 3000RPMs it just dies out. I'm not a mechanic, so some of this tech is spanish to me! I also read the other threads that say no aftermarket part is available yet.

So what do I need to get this thing driveable again? Do the parts from Dodge-wholesale work, at least till Jeep releases something this summer? My jeep can't drive right now, I can't sit around waiting for Jeep to make a part!

Help!

There is no "improved" part. You will have to order the same part that failed. You can mod that part or leave it as is and hope it works. Since you have codes and timing issues, I suspect you may be past that point now and may need serious engine help. Was anything damaged during the lift install?

Nope, totally inspected all the work they did, they checked all the usual suspects. Jeep ran 110% when it was dropped off. As I noted, the mechanic noticed the distributor was a bit loose when they started looking for issues, so he thinks someone was already there messing with it. Even after he tightened it and played around with the timing, it just ran rough. He has another 05 in the shop with 90k on it, so they compared some of the readings on the scanner between the two and said nothing really jumped out at him as an issue, other than the CPS error, CEL, etc..

I did forward him this thread for some info, hopefully he will pull the OPDA first thing in the am for inspection. I guess changing the oil isn't a bad idea either to see if there is any metal in there?

Why would the distributor be loose? This is the second incident where someone has had trouble after a lift install (I think it was a MML for the other example). That is actually a good thing though since a loose distributor can create timing issues.

You will need to pull the OPDA and inspect for wear. Assuming things are shot, you have to order a new one. You can put it in and cross your fingers. I would recommend doing the FogMOD as added insurance. At this point I'm in a "show me" state of mind with regards to any "new and improved" OPDA's that are rumored.

Follow the instructions for TDC on the first page to make sure the distributor (OPDA) is in the correct position. A tweak to the left or right might set you straight for the short term, but I'd bet the OPDA gear is in bad shape.

Yes, this was a bodylift, and MML install as well as a 2.5 OME kit, all went on at one time.

Not sure why the dist. was loose, but he said the wire loom that connects it was also out of the little holder thing there, so he suspects someone was messing with it.

He said he did play with the timing a bit, couldn't get it to run right.

Hopefully he'll pull it in the am see the damage, get the new parts and I'll be ok.

Remember that the OPDA only adjusts the fuel injector timing. A VERY small amount of movement will throw the codes. The OPDA hold down bolt is very tight from the factory because they don't want people moving it attempting to time the ignition (my opinion) so if it was loose someone must have been "messing" with it. If it turned when doing the lift, that may be your whole problem & the OPDA MAY be OK. It is still a good idea to pull it & check it out. Worst case you may need to find someone with a DRB III scanner to zero it back in. If the wiring was pulled from the holder, it may have turned a lot. The CPS should be at about the 4 o'clock position as a starting point. Definitely try the TDC method Willy has on page 1 first.

Oook,FogMod offically done!

Couple of side notes, 1. I didn't use a thread in grease nipple, instead used a pound in style. Reason being my tap was bottoming out before enough threads could be cut.

and 2. On a more interesting note, after I drilled the hole for the grease nipple and pulled the factory plug out. I decided before I drilled through the bushing, I would plug the grease fitting hole and see if air could get to the shaft somehow. I discovered that oil was "bubbling" out due to air pressure. Normal? others witness this?

Thanks for all the help guys! If it wasn't for this thread I would have never pulled my OPDA, as I was getting zero symptoms. Its a good thing I checked, as from my previous pictures, she was very close to failure!

Even though you have a 06 it is possible that it was pulled to do the EO5 fix. This was to replace the gear only, supposed to be only on 05's , but I can see a dealer performing it early on to try to solve the problem.

Your still under the 36K mi warranty. Any decent dealers near you? I'd say find one with a good service writer and have them inspect it. Best case (without a moded OPDA) you just have them replace the OPDA for the $100 minimal charge. Your cam may be damaged, though, and they'd have to replace it and lifters, too.

Don't forget, the warranty is either 36,000 miles or 3 years, whichever comes first - he's probably out of warranty by time. My Jeep only has 12,500 miles, but it was out by time as well.

As Willy says, you need a bottom tap to make the zerk’s threads. Press-in is probably an OK option.

You know, I had the same bubbles when I pressurized mine. They were very small bubbles & hard to judge, but I didn’t think it felt like grease. The bubbles were coming from at or near the bottom of the bushing near the seal. After bubbling for a few seconds they stopped & I could not replicate the process again. I thought it might have been water from my compressor. It took a lot of pressure & the size of the bubbles makes me think that grease would never find its way to the shaft.

It has been noted here that it is better to grease the OPDA with the engine running to better distribute the grease.

Thanks for all the info and research!

My question is how do you break in the gear on a new OPDA? Special grease? idle for awhile? special proceedure??

My story..... 05 LJ, 40,000 miles, second owner, no warranty. No problems/ symptoms. Pulled my opda after seeing this thread. Gear has alot of wear, shaft spun freely. I didnt pull the gear and inspect the shaft, just figured it needed replacement. Didnt want to mess with just replacing the gear. Switched from regular valvoline to VR-1 10w-30. Just recieved the new opda that I ordered from dodge wholesale in link on first page. Trying to decide about modding or just taking apart and greasing it. But concerned about breaking in the new gear to not-so-new camshaft gear. Thanks again for all the good info and suggestions!!

On a whim, I called Superchips today. Spoke with a very informative engineer who is the Jeep programmer. He was not familiar with our problem. I gave him the link and asked him of the possibility of using an 04 OPDA unit and using a chip to reprogram the 05 and 06 computers to read the signal it gave. He was going to read this link,but felt that they probably would not do anything. He said they were working on 2011 models and ours being only produced for 2 years that they couldn't budget for it.

I'm hoping he will at least be curious enough to look at this link and do a little thinking on his own.
