Reason for concern?

When I was changing my air-filter for the first time (14,000 miles) I started to undo the air box clamps to take out the old air filter. When doing so I noticed that the hose leading to the engines air intake completely came off. When I inspected the screw/clamp that holds the air hose in place it was VERY loose and basically was just in-place this whole time without and airtight seal. I was also a little surprised that the air filter was not as dirty as I thought it would be.

I put in the new filter and tightened the clamp with a good 6-7 turns. I wondered how this could happen and only solution I could think of was either the dealer took it off and forgot to tighten it when they replaced the water-pump at about 3,000 miles or someone opened opened my hood and did this just for the love of it.

Before discovering this I've felt like the engine was being sluggish compared to when it was newer. I could be a little paranoid but is this reason for concern? Should I take it to the dealer and bring this up for a check-up?

You obviously didn't ingest any foreign objects or water. You would have noticed that immediately but you could have ingested some extra dirt.

Have been driving a lot in dusty condition since you engine performance became sluggish?

Not really. Mostly freeway-traffic conditions. When I changed the air filter I also changed the oil and put in 5W-30 instead of 5W-20. (Guy lied to me, said synt. only came in 5W-30, will be switching back next oil change). But I've noticed the sluggish performance before changing to oil.

I doubt that your sluggish performance has anything to do with the clamp being loose, unless it scored the cylinder walls and wore down your compression rings. Only a compression test will answer that question!

Yes, you probably ingested some silicon (dirt), but since you just changed the oil, then a oil analysis would be to late.

If it did any damage to your oil control rings, or lower end bearings, then it will show up as a issue very soon. Oil pressure drop for lower end, and blue smoke out exhaust, along with a oily tail pipe end, caused by the oil control rings being damaged, and or scored cylinder walls.
You may also develop a noisy engine if this was to happen.

I really doubt that just driving it down the highway, would have ingested enough dirt to cause a serious problem, but how long it was loose is the real question. If it has ran about 11,000 miles that way, well that is not good. If you live in a dusty environment would also play a part in it.

All that you can do now is keep a eye on it to see if something materializes. Maybe take it in and get a compression test.

I know that it's after the fact, but it's always a good idea at every oil change to look over your air induction system for damage, and clamp tightness!

Can't say I've noticed any of the symptoms you mentioned. Maybe the engine is a little more noise than usual especially at low RMPs (2,000-3,000) which is where I notice the sluggish performance. Seems like there is more sound than go.

I'm taking it in next Wednesday for a recall that was pending and I had no idea about. Good thing I came across a recall thread and checked my VIN. I'll mention the sluggish performance BUT should I mention the loose clamp I discovered? If there is a problem, I wouldn't want them to void the warranty blaming it on me.

I think that you will be better off to not mention it, but that has to be your decision!

Using 5W-30 isn't a problem. A lot of us use 5W-30 instead of 5W-20. I know a dealer that uses 5W-30 when technically 5W-20 is "recommended" and it's documented and not an issue. Keep in mind the oil weight that's listed is what Chrysler "recommends". They don't indicate "absoulutely must use" or bad things will happen. Using 5W-30 isn't the problem. If you're more comfortable using 5W-20, that's fine, but don't think it's a major issue.

^^^Agree, it's a CAFE thing, that has been confirmed by Chrysler/Jeep Technical support! Use either, or! The most important part is the 5W for start ups!

I did do some reading in regards to the whole 5W-20 and 5W-30 situation, there is a nice little thread on it here. Only reason I'm looking to switch back is I don't want to give them any excuse to void my warranty should an issue come up that has something to do with the oil. I even got extended warranty, which is why I was concerned if I should let them know about the loose clamp. But thanks for the confirmation since I was considering changing it this weekend before taking it in next week.

Your warranty can't be voided simply by using 5W30. But, if you're more comfortable with following Chrysler's "recommendation" then that's all that counts.
