2005 Jeep unlimited engine noise

[UnlimitedLJ05]

Here lately every now and then after my Jeep is first started I hear a noise like something is caught in the fan clutch but, the noise goes away so quick is really hard to pin point the problem. It last about 2 to 3 seconds but, it does it once in a blue moon like once a month or so. Engine runs great and smooth so I'm at a loss as to what could be wrong with it. Any one have the same problem? I have 94k on the Jeep.

Could be the beginning of your opda
(Oil pump drive assembly) going bad.

Man I hope not. The only thing I have done to the Jeep besides maintenance as been a whole new cooling system aside from the heater core. My Jeep has been doing this noise for about four months or so and has only done it a handful of times I guess I will have to keep an eye on it.
