|Hotshot||Ordered the crown OPDA yesterday from Quadratec, paid extra for overnight shipping, less than $140.00 for part and shipping from PA to CA. The brown truck showed up a little while ago and I installed the new one. Just like the video showed, it was a easy repair. Appreciate the help.|

It was not a recall. There was a TSB (Notification Code E05) on a few early ’05 build dates that affected the OPDA gear. Not the same issue & TSBs are not necessarily free repairs either. This one was since it applied to new vehicles, most of which were still in dealer inventory & the owners of the ones already sold were contacted. The repairs would actually have been warranty repairs. (Mine included.)
From the bulletin:
“The problem is... The oil pump drive gear on your Jeep (VIN: xxxxxxxxxxxxxxxxx) may
wear out prematurely and cause engine failure due to a loss of oil pressure.” …

The OPDA (Oil Pump Drive Assembly) is a known issue on all 05-06 4.0L engines. There are multiple threads on it on this forum. Don't drive it until you get it fixed as it can cause a lot of damage to your engine if it seizes up. The problem is that the upper bushing on the shaft of the OPDA gets starved for lubrication and galls the shaft, creating a lot of drag on the shaft. This wears the drive gear and it's mating drive gear on the cam shaft. If the shaft seizes, the gear on one of both will disintegrate, which stops the oil pump from spinning, while also sending metal particles through your engine.
The fix is to replace the defective original equipment LDI unit with a unit manufactured by Crown. Don't have the dealer replace it with another defective LDI unit. The recall done in 2005 did not address this design defect, so all OEM LDI units (both Rev B and Rev E), are still likely to have this issue. The good news is that if you aren't throwing any codes yet, you can use the target wheel of the OPDA to ensure you have your engine at TDC on the compression stroke in order to ensure the new unit is timed correctly. And always reuse your OEM sensor, and save the Crown sensor as a spare. You don't even need to undo the connector for the sensor, just unbolt it from the OEM unit and bolt it onto the Crown unit. There are some good videos on YouTube that will help you understand this repair. It only takes 15-30 minutes to do and requires a 3/4 in socket and normal sized 1/2 drive socket wrench to spin the engine around to TDC on compression stroke, a 13mm wrench to undo the retaining bolt for the OPDA, and a 10mm wrench to undo the retaining bolt for the sensor. Oh and the Crown OPDA costs less than $110.
Here's a link to buy the Crown OPDA:
Here is the video I made after doing mine the last time:
I like this video the best for showing how to align the OPDA before removal:

My 2005 just started doing the same thing. I took the belt off to confirm it wasn't a belt tensioner, or idler pulley. Planned on replacing the belt anyways so it was a good time to do it.
I Searched online and what I'm reading is its the oil pump drive, common problem is what I'm reading. Also read that it was a recalled item. I kinda doubt they'd fix it on the recall beings it's a 05, not a big deal though. Napa wants $150.00 for the part.
Looks fairly simple to change, put it on top dead center, unplug the camshaft positioning sensor, remove the hold down bolt, pull it, and pop the new one in. Was reading that the dealer gets around $265.00 parts and labor, for those who don't feel comfortable doing it themselves.

Did he use a stethoscope or not? It isn't rocket science trying to figure out a loud noise.
In personal experience, the bearing(s) makes a ticking noise for the oil pump drive shaft when they go bad. I guess a squeal is possible.
Overall, he sounds like he doesn't know what hes doing and I would go somewhere else if you haven't already paid a diagnostic fee/deposit.

Alright, i feel like this is never ending.
Just got the jeep back and it wasn't the belt tensionor. But I talked to the guy and its not actually the camshaft sensor either. It is the part that the camshaft sensor plugs into. He said there are two bearing in there and they are shot and I need to replace the whole thing.
So now im back to where I started and its going to cost me around 300$ to fix and they won't be able to get the part until Tuesday or wednesday.
Does that make sense to you guys?
And the part was under warrenty for 3 years or 60000kms, im at 57000kms but 3 years was August 08.
|03-05-2009 06:15 PM|
yup...much more likely. I'm not sure how someone gets cam sensor from belt noise
hope it all works out.

|fox86||Alright, thanks alot for the help guys.|

Alright so i took it to another garage and the guy is pretty positive it isnt the cam shaft sensor and that its the belt tensioner. Before we opened the hood he said he thought he knew what it was then listened with his stethoscope(sp?) kind of thing and said that hes sure its that.
Does that make more sense?
He said it will be around 100$ with labour and hes going to drive me to work and come pick me up to get the jeep at the end of the day too, seemed like a geniune guy
