Just a week ago my jeep started making a funny noise under the hood near the back passenger side of the engine...
Kinda sounds like a turkey being strangled.
We replaced the belts and the pulleys.. but that didnt fix it.
I have a toyota person telling me its a cam shaft synchronizer but wanted to see if that was a major problem in jeeps to cause that noise..
Sounds like you may have a bad OPDA! Dont start or drive your Jeep, you could blow or may have blown/damaged your engine. Premature wear of the Oil Pump Assembly gear. Laughing Monkey's is the term as said by previous responder.
I wouldnt go to the dealerahip for it. They like to get us to pay more even though its a defect. I'm not sure where to get the part and I am on my phone now so I can't get a link. I can get it to you when I get home if someone else doesn't get it to you first.
