For those of you using M1 TDT, I just got my O'Reilly's ad - $19.99 a gal. Good price??

IIRC, last time I saw it at Walmart it was closer to $25/gal.
Bought 3, 6qt cases at NAPA @ $4.99/qt - $19.96/gal a little over a week ago.

$19.99/gal seems on the money.

The new OPDA arrived. Same POS as before, REV-E. But, it's new.

This is the same price I paid for one the first time before it became big news. Then it went up to nearly $400 now back to $135 shipped? I wonder if they are trying to get rid of the remaining stock for the supposed July update about this problem? Either way, much more peace of mind having another new new. It'll sit around until needed.

My brother bought an 05 LJ yesterday and drove it from IN back to wheres hes stationed in KS. About 150 miles in his check engine light came on with a p0344 code. I found this thread and told him about it. This is what his OPDA gear looked like when I told him to check it. This is what he sent me.

I am glad I found this thread. I just changed my oil, and did not get the right stuff. Oh well, my TJ is very low mileage, so I will run out this oil and put in the VR1.

This thread documents some excellent hard work, thanks to all who have contributed.

I have a 2005 Unlimited with a build date of October 2004. I have read on here and other places that 05/06 models have premature oil pump failure as well as camshaft problems and I know the earlier models with the distributorless ignition systems had a slightly different set up but, mine is set up just like what I see here. I have 85k on mine and haven't had any problems and show no TSB or recalls I was just wondering if I should be worried or not? I have been using the Valvoline VR1 10w-30 with the ZDDP levels the flat tappets need thinking that it will be my safest bet but, I just wanted to know everyones thoughts on all this?

Thanks,

Ej

You will know for sure when you pull it. There is a video on the first page using the sharpie method. In 20 minutes you'll know for sure what shape you're in. In my experience, the norm is premature wear. There are instances of OPDA shaft binding (that the FogMOD eliminates or at least substantially reduces), however the time frame of failure is not consistent. Some times you get a warning squeal, some times you toast an engine. It can happen at 12K, 50K, 100K there is no rhyme or reason for the delay that we have identified here. Maybe oil type, driving habits, break-in, we just don't know.

The concensus here is to complete the FogMOD and change the oil to VR1 or M1TDT. Again everything is outlined on the first page. Doing nothing is not advisable. There are some who have had no problem and some who need a new engine. I would recommend having a preventative outlook.

1. Check it for wear (highly likely at 85K). Free.
2. Replace with a new unit at a minimum. $120ish, link on first page.
3. FogMOD is highly advisable since shaft binding has been seen and can cause catastrophic failure. $40-60 ball park for tools, or having someone do it. If you're not good with machining PM me.
4. Run VR1, M1TDT, or ZDDPlus additive. $40 Oil cost

Whatever you do, don't do nothing.

Good luck.

Wait, that can't be true. According to a few in this thread, that problem is caused by a lack of ZDDP in the oil so therefore the problem cannot be fixed by anything except by having more ZDDP in the oil.

I don't believe anyone in this thread or any opda thread thinks that Jerry. Obviously its a poorly designed unit. And we know you believe zddp is pointless and you know everything about everything.

I check in on this thread from time to time. 06 with 97K+ here and no symptoms so far. Still interested if there is an ultimate resolution here.

This rumor was started in this thread. I'm in the "I'll believe it when I see it." If I were you I'd plan as if it were not true. The risk is too great and the mod is too cheap not to do it.

When a faulty component design puts undue resistance on a moving part and as such puts more pressure on a gearset, the gears will obviously wear much faster than intended.

Using a lubricant with known higher anti-wear properties would likely help to diminish the effect of gear wear until a solution is available that would eliminate the source of resistance.

Not rocket science....
