I just bought a 2005 unlimited with 32k miles on it and picking it up tomorrow. Now I'm worried.

Ok...so here's some pics of my cam and OPDA gears with about 2 hours of runtime on them:

Cam:


OPDA gear:


The cam looks fine, but I'm a little concerned about the OPDA - while it's more polished looking than either of my old gears (that were mated to my old cam) it still has a few scratch marks in some of the wear spots.

Because of that, I decided to install my last new OPDA gear that I had in reserve. After I put it in, I let the engine idle for 15 - 20 minutes, based on something someone linked to in one of these threads - it was some comments from a GM powertrain engineer about proper break-in for a distributor gear. Needless to say, the break-in for a distributor gear and a cam seem to be the complete opposite of one another...so how is one supposed to break in a new cam/distributor gear when it seems the correct process for each will destroy the other?

Anyway, I'll put some hours on this one and see how it's doing this weekend. Ugh.

If you are the second owner the 7/70 powertrain warranty will still be in effect until it gets to 7 years old. On my 05 that will happen in November of 2012. You do have to have a Chrysler dealer transfer the warranty to you.

Now whether the warranty is worth the paper it's printed on is another story.

I took pictures of my OPDA at 48k and again at 60k. It's hard to tell wear difference because of lighting differences in the pictures. But to me it doesn't look like the gear thickness is significantly thinner in the second picture. What do you guys think?

All the 2005-06 models are affected. There is no date period. That is all bunk. So yeah that sucks.

Sell it if you don't want to be bothered. Since you are aware of it, make the dealer aware of it. Have them pull the OPDA and inspect it and the cam shaft. Maybe (though extremely unlikely) they will fix both. The common reply is that everything is normal. And while wear is normal, the amount of wear we are seeing on the bulk of these units is premature (arguable that we are the vocal minority).

These are cases that are arguably the normal expected wear with the 2005-06 units. Looking at older OPDA's from 4.0's the wear spot is much smaller.

This is treatable and not the end of the world. How effective the treatment is, is still debatable and the potential is still there for failure at any time whether it's 10K, 50K, or 100K. Break in is likely the problem coupled with lower ZDDP levels than the 4.0 prefers. Presumably the gear and camshaft are the same as pre-2005 units and while they have failures too, it is very uncommon.

Do the FogMOD, change the oil to a higher ZDDP formula (VR1, M1 TDT, ZDDPlus) and monitor the OPDA situation. I think gears breaking is uncommon and catastrophic failure is unlikely if you keep an eye on things. Be prepared to swap the gear every blue moon. Depending on what TJJP77 finds a new camshaft and OPDA may be required.

I was really hoping things would look good. Good luck with the next gear.

Ask them the date the vehicle was originally put into service. If you are the second owner the warranty goes 7 years or 70k miles from the data it was first registered.

I had my OPDA, cam shaft, lifters, and oil pump replaced under a transferred original warranty with no issues with the Chrysler dealer.

That doesn't sound right. The original warranty was 3/36 bumper to bumper and 7/70 powertrain. You could still be under the powertrain warranty.

I had the warranty transfer to me upon purchasing mine and it's paid for itself mutliple times over. Just had the OPDA replaced under warranty as well.

Keep in mind you need to be the second owner to be eligible for the transfer.

Keithert is correct that the warranty is 7/70 for the powertrain on an '05. They lowered it the following year, but I've never heard of a 5 year/70k mile ??

Another one bites the dust. About 4 months ago I experienced the same problems. I found an older assembly and swapped the opd gear. It worked until this weekend. I'm thinking I should just do the same again to clear the code and get rid of it.

Where can I buy a new gear?

Dealer near me is selling the opda for $180. I'd rather swap a ear again.

Would I need another gasket?
