Can we get a sticky on this thread, and locked, before the thread gets too big with questions.

Excellent work combining the major meat of the other threads into this post. Nice work Willydigger.

I'd agree with a sticky, and the deletion of all posts not from willydigger or Fog contributing to this thread (including mine) to keep it clear and clutter free. I don't even look at the other threads anymore as there's just too much crap. This is clean with everything you need. another vote for "sticky" use.

Again Great work to Willydigger for making THIS thread. Of course, great work to Fog and the rest for the other contrubutions and work in the other threads.

Best of Luck,

Mike

A sticky would be nice. Locked is another issue. I think questions are important and should be allowed. The point of this thread compared to the camshaft thread, is all the important info will be in the beginning for reference. This way when you need some info you don't have to hunt through a hundred pages to find it.

It will take some time on my part, but we're all in this together. I don't mind helping out. Maybe we can get it moved to the write-up section so I can get a sticker out of it.

Great job dude! The "Whats this and why is it so Angry" thread was mine. I really wish you guys would have had all this info when I was figuring out how to swap mine out. What I didnt see earlier was the lifter damage. Ive got a nice tick and Im wondering if its a lifter due to the OPDA problem...

Has any additional effort been put in to convincing GM that this is a legit problem? I would imagine if so that no ones really got anywhere with it.

OK, so, I know we can all one at a time call and complain to GM but those complaints often fall on deaf ears. And thats assuming theyre actually willing to acknowledge there is a problem. Then, there are petitions, which are completely useless. So, is there a way to legitimatize the volume of actual problems to the point that GM would acknowledge it?

I can only wish that Jeep was a part of GM so the quality would be higher. Sadly Jeep is ran by Chrysler not GM which means all complaints will fall on deaf ears.

Just do a little googleing about Chrysler and their record with ignoring recalls even on stuff like seat belts and such. Your more than welcome to try but your not going to get the time of day from Daimler Chrysler.

hmmm...wonder what about it is patented. Seems like someone could change the design enough to be no longer covered under the patent.

I guess i'm going to buy a new one and make these changes. HUGE thanks to willy for making this thread.

Forgive me if this was addressed already. I've read through this thread twice now, but I may have missed it.

If we check for damage to the OPDA and find some, then you are recommending a new OPDA. Are you saying to make the mentioned modifications to the new OPDA then? Wouldn't a new OPDA address the issue without having to make the mods?

Reason I ask is that the TSB stated that approx. 16000 engines may experience the problem. So that tells me that there was a change made at some point. Since the problem seems to be with the OPDA itself, then doesn't that mean the OPDA was "fixed" by Chrysler, and a new one wouldn't have the same issue? If all OPDA's were made the exact same for 05-06, then why are only 16,000 engines affected by the issue?

Is there a date range, or some other way to identify if our engine may be affected by this issue, other than pulling the OPDA (which I plan on doing anyways for some peace of mind). My Jeep has about 80,000 miles on it. I'm just curious if I need to get out there and address this right now, or if I can wait until I "get around to it".

I appreciate the OP taking the time to compile all this information. I started reading through the other threads that talked to this issue, but they were just so huge and there was far too much back and forth. It was hard for a new guy like me to try to filter through all the excess and get to the meat of the problem/solution. Thanks!

We debated this topic on one of the other forums I am on. It is a long thread, but good info in it regarding ZDDP.

There is no date range of affected OPDA's. The TSB may claim that and Chrysler may say it, but don't for a second believe it. All the OPDA's for 2005-06 are the same. There is no difference in revisions. IMO, they all are faulty and they will all fail. There have been reports that some OPDA's do have a way for grease to get in. Maybe that is true, but I have yet to see it. Maybe the difference in oil will prolong it, maybe there is a defect that allows grease past. Putting a hole in the bushing is one way to be absolutely sure. I will update the post shortly with this point.

Look at it now. Some last a while (mine lasted 60K) some blow up at 15K. Some give warning (mine squeaked) and some surprise you with a drop in oil pressure and a new motor. It takes 20 minutes to pull it. If you have the wear, buy a new one and make the mod. If you don't have the wear, take a picture so I can post it.

Nice write up. Where were you last year when I had to figure this out on my own?
