i have 60k miles on the clock and haven't had any symptoms, should I keep driving it until something happens (which could I be one of the lucky ones?) or should i just get the part and have it installed? Can a shop do it? What happens if I just keep driving it til it blows?

Just an update. I got around to doing my variation of the oil mod and things went relatively smoothly. Unfortunately, I broke a bit drilling one of the holes into the reservoir, but at least I got most of the metal fragments out and proceeded to drill new holes. Oops. Anyhow, I filled the cup with a bit of oil, bubbled through the holes, and out the drain. Right now, I'm leak testing the hardware and I hope to get the balls to install it sometime soon.... *sigh*



Note I used a larger bit to shave down the ledge

I would pull it first. See where your wear level is. If you are one of the lucky ones, your wear will be minimal and I would consider FogModding the existing OPDA. If you have a lot of wear, I would order a new one and FogMod it.

If you continue to run it, if it fails you will starve your engine of oil and it will likely result in serious engine damage. A small amount of work (inspection) and possibly a small investment now will prevent that.

A shop should be able to easily replace one, but I would advise FogModding it for some added piece of mind down the road. I don't know where in Central PA you are, but if you want you can come down to Baltimore and we can get you straight.

This is starting to scare me a little, i'd pull it myself but I know the way I have with mechanical things it will blow up in my hands or ill forget which way it goes in. is there any sort of step by step?

There is a video on the first page under the Removal Section. It is pretty easy. The hold down bolt is hard to reach and sometimes very tight. Mark the position of the target wheel as it relates to the sensor. Watch the video a couple times until you are comfortable. The hardest part is working up the nerve!

Once it's out don't start the Jeep. Leave it be until it's reinstalled. Reinstall the same way it was removed and get the hold down bolt tight, but not too tight.

The video will also show what happens if the oil pump turns so it won't reinstall easy. A long flat head screwdriver will fix that and honestly if you remove slowly you shouldn't have a problem. I was trying to remove it without being in the way of the camera.

Will I know when the part fails? Will there be a drop in oil pressure or a check engine light so I know my engine won't be starved of oil?

Read amongst the first 10 posts again. Some have lots of warning, others have little. I wouldn't wait, but if you do, when the monkey laughs, shut it down immediately.

I think there will be both. Definitely the CEL. It doesn't take long to destroy an engine though.

You may get lucky like I did and get the "laughing monkey" screech from the OPDA itself. There is a link on the first page for that too. It's a little different than a belt or pulley squeal.

I had no CEL with the monkey; it only lit after it was too late.

I think he was referring to loss of oil. You will get a CEL for that, though it may be too late at that point.

I also wouldn't count on the Monkey for warning. Some get it some don't.

I wouldn't sit by and wait for something to happen. I would pull it to know for sure.

Was reading this post before I left work today and wouldn't you know it, screaming monkeys from the engine compartment when I started the Jeep. 2006 Rubicon with 39K miles on it. I got out and put my hand on the OPDA and you could definitely hear and feel the vibrations/noise.

Stopped by the dealer to see if maybe there was some warranty coverage, none. They quoted $400.00 plus for replacement. Told them no thanks, for that price I'll do it myself, and thanks for the lack of support on this defective component.

Is the part number the same for both the 05 and 06?

Yes. Follow the info on the first page. Good luck. If you need any help with the mod let us know.

You guys have done a great job documenting the problem and making the repairs. Saw the video of replacing it, seems pretty easy. Beats paying an extra $300.00 to have someone else do it. Hope it's in stock, I paced an order for it.

I recently did the brakes and replaced the water pump, thermostat, hoses and belt with the help from this forum, good stuff.

Thanks again.

Denis
