One of the mods would be better, but to occasionally squirt would be better than nothing. I'd also use the same oil as is inside, but that's just me.

Good point. I wondered if I would contaminate the engine oil by using a different lube.

Kinda tough to get any lube in there though.

I can't say for certain without being there. Here are some facts to help you figure it out.

Laughing Monkey is the key indicator the OPDA is bad.

Ticking is a general I6 symptom/issue/condition that can be a problem. I think most of us here have had the tick, however IMO it is not related to the OPDA problems.

Typically for me the tick happens after EVERY oil change and occasionally on start up.

I relate it to a main seal leak. Most jeeps have it, and it can be minor or major. You'll have to decide what you're comfortable with.

To determine the quality of the OPDA check gear wear, and more importantly check to see if there is binding. That may mean a full disassembly.

Even with a brand new OPDA, you may still have a tick.

This was very helpful and somewhat good news.

Hardly any wear on the gear, only ticks sometimes and no laughing monkey.

Did you mean rear main seal leak? I do indeed have a rear main seal leak but the drips are only minor and nothing to worry about at the moment. I was planning on doing my rear main seal and oil pan leak soon, though.

Absolutely not. You say the gear shows little wear the gear going bad is what destroys the engine. Do one of the mods that are shown here to make sure your shaft/bushing is lubed. Tear that sucker apart and check it. Post some pictures and people on here can assess what you have.

Which is indicative of lifter noise. Very common on these motors as they have sub-standard lifters!

Ditto. I think what many think is a tick in the OPDA is incorrect. I can't think of anything in there that can tick. When you feel a rhythmic "tick" by putting your hand on the unit I think the only possible thing that it could be is the shaft going up and down due to the end play. These OPDA's have a lot of end play.

Rear main has nothing to do with the ticking or the OPDA unless the leak is so severe you run out of oil. If it needs fixing, fix it, but don't confuse it with the tick.

How many miles do you have on your engine and what oild do you use?

97,000 and Mobile 1. I don't know what the previously owner used, but I've used nothing but good oil and filters since I've got it.

And I just read your lifters post from a couple of days ago. Looks like I'll be going to shell more often than cruddy, cheap gas places.

You want to use a ACEA-A3 oil which Mobil 1 High Mileage is. FYI, the Mobil 1 "Extended Mileage" is ACEA-A1 which is also good, but the Mobil 1 High Mileage is more gooder. It has a little more zinc in it and is meant for older engines. Many get confused with putting a "High Mileage" motor oil in a new or newer low mileage rig. But in actuality the 2006 4.0 engine needed High Mileage oil from the factory as it was an old school flat tappet engine. The EPA wanted oil makers to lower the zinc content due to catalytic converters or some BS. But the low zinc oil and flat tappets don't mix. Of course that has no bearing on the OPDA issues we have as only the lower bushing gets lubed by engine oil anyway and any old oil is fine for that.

The detergent in gasoline like Chevron with Techron really does help keep the valve stems clean. I actually try to use it in all my vehicles for that reason. The Texaco and Shell are also good. Just try to not constantly fill up with raw gasoline. Interesting enough, I find on 3 of the 4 vehicles I drive the gas mileage is better with Chevron gas as well. Probably not enough better to cover the added cost, but enough to make the difference much less. I had an '04 Turbo PT Cruiser that was just a fun Hot Rod. Running the Chevron 93 octane gas made what seemed like 20-30 hp more than any other 93 octane gas.

Bottom line is----many think lifter wear/noise/issues are connected with the OPDA failing. Only way this happens is if you get so much wear at the pinion/cam worm gear that metal is flowing through the system and destroying the lifters, which has happened, but that also destroys the crank bearings, cam bearings, and just about everything that gets lubed by the oil. If your cam worm gear and OPDA pinion gear looks good but you have a tick them I'd suspect lifter problems. If the ticking stops upon warm up don't worry about it. Worry about more worry worthy things like spiders under the toilet seat or flat beer.

Go back to page 183. There is a brief discussion. You can transfer the sharpie marks or use the alignment holes.

Easiest way and most positive way is to just turn your engine over with a 3/4"socket at the front of the crank shaft. I have an advantage as I am tall and have long arms. I just reach down from the right side of the Jeep and using a ratchet turn the engine over until the 2 holes are lined up. Don't worry about the fan as it is free spinning when the engine is off.
