Laughing monkeys
Stripper guy Mod $60
New OPDA $140/shipped
Repaired & modded myself for total investment = $200Chrysler was not contacted but according to service repairs the gear was swapped @ 30k. The old OPDA also had Sharpie marks on it so the previous owner had looked at the unit at some point.
All is good with the repair currently.


I had the parts on hand & at first sign of laughing monkeys swapped everything out. My gear was in excellent condition & looked new. However the shaft coming from the target wheel had a lot of heat markings. The end of the shaft had a small indention on the edge of the tooth that fit into the oil pump slot.

OPDA/Camshaft

It was approximately 8 month ago when my LJ started with problems.
1. 2005 LJ Rubicon build date pending, mileage 48,000
2. Thought I had "laughing monkey" but it turned out to be something else. However the #6 cylinder started missing and only got worse. Took it into a shop and they scoped the 6 cylinder and found metal. Basically after they tore it down the lifter was almost as bad as the original post picture and the cam was flattened.
3. & 4. I had two choices, one rebuild upper end with no warranty, two remove and rebuild. I chose #2. total cost of R&R was right at 4,200. I did get the jeep back with old OPDA in it was still concerned so I installed stipperguy mod. Approximately 2000 miles on motor no issues. Rebuild shop did indicate they thought he old motor did what it did because the zink in oils had been removed around the same time jeep was new and or still braking in.
5. Did not contact Chrysler, I am the second owner.
6. N/A
7. not yet.

'06 TJ with a little under 30k, not sure about the BD but it was first sold in early '07

2. Brief description of the problem and any collateral damage. Please include pictures if available.
It suddenly sputtered and quit and my wife was barely able to get to the side of the road.

3. Actions taken to fix the problem
Wasn't aware of the problems so it was replaced with an OEM one by the local dealer.

4. Approximate cost of repair
Zero to me since we had an extended warranty.

5. Did Chrysler pay for or reimburse any of the repairs?
Not to my knowledge.

6. If Chrysler did pay, what steps were taken to make them pay
NA

7. Has the problem returned?
No. (knock wood!)

Not sure if anyone else has had this issue, but I now hit a "rev limiter" at ~32 - 3300 rpms and the motor will not rev higher and bounces the tach. The OPDA squeals at 28 - 3000 rpms.

It's still under warranty, but as of right now the dealership refuses to do anything. I had the motor rebuilt twice already for collapsed lifters. It was rebuilt and a week later the bottom end came apart (hence the 2nd rebuild). Never been right since. Might be taking it in this week to the dealership and showing them the new issues.

Will keep this updated as it progresses. I have an '06, not sure on actual build date with just under 47k miles.

this thread saved my Jeep - for now

1. Year, model, mileage, and build date of your Jeep.
2006, Wrangler TJ, 27, 500, (don't have right now)

2. Brief description of the problem and any collateral damage. Please include pictures if available.
engine died on me on the highway - over heated, check engine light, and laughing monkey noise prior (didn't know what it was at the time)

3. Actions taken to fix the problem
dealer said it was a bad cam sensor, had it replaced. died the day after repair. repaired again, died again. spent more than 2 weeks at the shop while they couldn't diagnose, then called an 'expert' in from northern NJ - couldn't find the cause. Googled and found this thread. presented dealer with repair code, information, and repair instructions from this thread - had the distributor assembly/oil pump drive assembly replaced. has not died since. engine now makes very high pitched running noise and mild grating noise. took several oil flushes to remove metal from oil.

4. Approximate cost of repair
$400 for OPDA replacement only - not including prior sensor replacement

5. Did Chrysler pay for or reimburse any of the repairs?
NO

6. If Chrysler did pay, what steps were taken to make them pay

7. Has the problem returned?
No, however engine noise is getting worst.

I'm very ticked at this. We're the second owners. Bought it 2 yrs before this from the dealer that sold it to the first owners. It had just under 15K miles on it when we got it. It was towed behind a class A camper and used seasonally.

1. Year, model, mileage, and build date of your Jeep.
2006 Wrangler Rubicon TJ with 49,702 miles and built in 01/06

2. Brief description of the problem and any collateral damage. Please include pictures if available.
I heard the "laughing monkey" for several days, and brought it to my independent mechanic shop, and they found nothing wrong visually, so it was cleaned and lubed. A couple days later, I was on a remote dirt road, and I lost oil pressure completely and triggered the "Check gauges" light. I was able to pull over before it started ticking too bad and I had it towed back to the shop ($75), under the predetermination that my oil pump had failed somewhere. Problem returned with the OPDA, I fear that the camshaft was damaged. TBD

3. Actions taken to fix the problem
Had it towed to my mechanics shop. Found the issue was in fact the OPDA, and found that it was a common problem for them to wear prematurely and that Chrysler was replacing them on a case to case basis (based on a TSB issued). I called my dealer and they "couldn't find any info on it". I got a new OPDA from the dealer and had it installed, at my own cost hoping that it would be the end of the issue, only to have the Jeep fall into limp mode at 3,200 RPMs once warmed up and the CEL P0016 code a couple days later. More work necessary to resolve the issue completely. TBD

4. Approximate cost of repair
$225 with new OPDA from Chrysler dealer, but soon after replacement, CEL came on reading P0016 and Jeep goes into "Limp Mode" at 3,200 RPMs (once engine warms up to around 150 degrees or so). Still need to diagnose the continuing issue and go from there. Further work is imminent, end cost TBD.

5. Did Chrysler pay for or reimburse any of the repairs?
No

6. If Chrysler did pay, what steps were taken to make them pay
N/A

7. Has the problem returned?
Yes, fear that the camshaft was damaged. TBD

This is a ridiculous issue to have on a vehicle with under 50,000 miles! I contacted my local dealership, and Chrysler directly, about the issue (and potential coverage), and got the runaround on both ends. I kept getting the "Well, it's not under warranty any longer, and it was never a recall...just a TSB. So We are not responsible for reimbursement or coverage of any kind." It has cost me a mild amount of money so far, and will surely cost a great deal more to alleviate the issue completely. This has however cost more than money, it has cost me my faith in Jeep as a company. They are clearly unwilling to correct an issue that they openly admit to be a problem, but rather sidestep the issue by issuing a TSB instead of a recall (clearly their reports did not meet a REQUIRED number).

Your shop did not get the OPDA properly aligned with the crank, that's why you have the error code. The OPDA hold down bolt needs to be loosened and the OPDA rotated slightly one way or the other. You can trial and error it, or you can take it to a shop with the proper scan tool to do it.
