Ticking sounds from under car?

Asked by Aug 31, 2015 at 03:25 PM about the 2004 Dodge Durango SLT 4WD

Question type: Maintenance & Repair

My new-to-me 2004 dodge durango has a certain ticking sound that I assumed was just hemi noises. I've been somewhat worried about it, and even looked into replacing lifters.

When I was out driving it today, I noticed that I hadn't fully shut the hood. I stepped out. I lifted up the hood to give it a listen at temperature, and the ticking sound wasn't as noticeable as it was when standing next to it. I poked my head under the car, and felt like it was louder down there.

Later on I did a bit more research, and took another listen, looking carefully at the engine and specifically the valve covers. I heard some noises that sound just like normal higher-millage engine sounds, injectors, a bit of a whirring from old bearings around the alternator or compressor, and the typical valve action noise. Nothing at all loud or out of place.

In fact, getting closer to the engine the ticking sound seems to have gotten less noticeable, and it seems loudest from the passenger side, and might even be sounding like it's coming from slightly behind the the engine or in the least to it's rear. However, it definitely doesn't seem to be coming from the top.

I'm assuming right now that it's exhaust. The exhaust is very, very loud, but, it's a 5.7 Hemi V8, not exactly a "quiet ride" either.

Neither of the mechanics, not the shop I took for a pre-pruchase, nor the Chrysler dealership where I had new plugs installed said anything about it - the dealer had given me a huge list of things to bring it back to schedule and a transmission gasket and a few other minor things I already know about needing work, so I'd think if there were an exhaust leak, they'd have mentioned it.

Thoughts?

I was going to say exhaust leak. Have it looked at by another mechanic to confirm.
