lugging-down "rattling" noise w/standard tranny
I have a question for you more auto-mechanic inclined than me (which
is probably most everyone who posts here often). You know that noise the engine makes when it lugs down? Kind of a clicking/rattling noise, especially prevalent when you shift into the next gear too early, right when you release the clutch and put pressure on the gas again? What specific part is making this noise. Does anyone know? I have been hearing it more lately, when I'm just driving normally, and there is no reason for the engine to be lugging down (I'm not shifting too early, etc.), and I'm wondering if something in my tranny or clutch is about to go bad that would cause this noise to occur more often. I still only hear it pretty close to when I first get back on the gas after changing gears. I'd like to catch any potential problem before it strands me. Thanks /Bob |

Re: lugging-down "rattling" noise w/standard tranny
That can be carbon building up causing the gas to ignite too soon. The
noise is pistons getting slapped around. A good run on the highway in a lower than normal gear is one way to clean it out. A pint of ATF or some use a pint of water and slowly trickle it down the air intake while running will clean it out. ATF makes a large cloud of smoke but work really well.

Probably pinging knock from lugging. its engine noise and not good to do.

Re: lugging-down "rattling" noise w/standard tranny
Model/Year: 1997 TJ w/4.0 I-6 and 5spd.
Like I said before, I am not shifting too early or driving in too high a gear to cause the lugging in that way. I'm not sure if my clutch/gas modulation timing is screwed up; I've always thought I shifted ok, and have driven a standard for a good 5 or 6 years (5 of those years part-time...shared vehicle, then full time this last year since buying my jeep). Mike, you mentioned putting a pint of ATF or water in. You said to trickle the water down the air intake. What about the ATF option? Do I put it down the air intake also, or do I add it to the gas tank? Is this "lugging" noise always associated with pre-ignition, (i.e. is the noise I hear when a vehicle lugs down the sound of pre-ignition), or is there ever another cause of this particular noise? I'm still horrible at diagnosing particular noises coming from my engine, so I'm trying to learn. I always thought that noise of lugging down (which sounds very similar, whether I'm driving a jeep, a celica, or a sentra) was mostly harmless, though not something one wants to make happen. Thanks for the advice and help.

Re: lugging-down "rattling" noise w/standard tranny
The page from your link talks about the causes of pre-ignition. Most
of the things it talks about I am not too familiar with. Please see below for the causes listed on that webpage, and my responses/questions/confusions: 1. Carbon deposits that remain incandescent. Um, ok. How do I fix that? Is that fixed by the water/ATF thing Mike is talking about? 2. Spark plugs too hot a heat range. So should I just replace my spark plugs and see if that helps? (I have no idea if they've ever been changed; I bought the jeep w/30k on it, and it now has about 48k on it.) 3. Spark plugs not firmly seated against the gasket. I assume changing the spark plugs, and making sure to "firmly seat" them in the process would take care of this potential problem? 4. Detonation or the condition leading to it. Um, ok. This seems rather vague. 5. Sharp edges in the combustion chamber. ???? How in the heck does one know if this is the cause short of having someone take the engine apart and rebuild it??? (Not something I have the know-how or desire to do myself!!) 6. Valves operating at higher than normal temperature because of excessive guide clearance or improper seal with valve seats. No idea. 7. Overheating Not a problem to my knowledge; temp gauge stays rock-solid at 210. 8. Ignition crossfiring. Induced voltage in spark plug wires that run parallel to each other for long distances. I doubt this is the issue. -- I think it's important to note that this noise is only happening as I'm remeshing the engine into the next gear when shifting. And I mostly only notice it while going from 1st to 2nd, or 2nd to 3rd. I don't think I've ever heard the engine make the lugging sound while remeshing the clutch while shifting from 3rd to 4th. One other thing; I don't know if it has any bearing. About 4 months ago, I had a shop replace my (cracked, go figure) original exhaust manifold. Could they have done anything wrong in the install that would lead to this beginning to start happening 3+ months after the install? Thanks a lot for your help with this.

Um, ok. How do I fix that? Is that fixed by the water/ATF thing Mike is talking about? 2. Spark plugs too hot a heat range. So should I just replace my spark plugs and see if that helps? (I have no idea if they've ever been changed; I bought the jeep w/30k on it, and it now has about 48k on it.) 3. Spark plugs not firmly seated against the gasket. I assume changing the spark plugs, and making sure to "firmly seat" them in the process would take care of this potential problem? 4. Detonation or the condition leading to it. Um, ok. This seems rather vague. 5. Sharp edges in the combustion chamber. ???? How in the heck does one know if this is the cause short of having someone take the engine apart and rebuild it??? (Not something I have the know-how or desire to do myself!!) 6. Valves operating at higher than normal temperature because of excessive guide clearance or improper seal with valve seats. No idea. 7. Overheating Not a problem to my knowledge; temp gauge stays rock-solid at 210. 8. Ignition crossfiring. Induced voltage in spark plug wires that run parallel to each other for long distances. I doubt this is the issue. -- I think it's important to note that this noise is only happening as I'm remeshing the engine into the next gear when shifting. And I mostly only notice it while going from 1st to 2nd, or 2nd to 3rd. I don't think I've ever heard the engine make the lugging sound while remeshing the clutch while shifting from 3rd to 4th. One other thing; I don't know if it has any bearing. About 4 months ago, I had a shop replace my (cracked, go figure) original exhaust manifold. Could they have done anything wrong in the install that would lead to this beginning to start happening 3+ months after the install? Thanks a lot for your help with this.

Re: lugging-down "rattling" noise w/standard tranny
Both the ATF and/or the water go slowly down the intake.
I have been told by lots of folks that water is as effective as ATF at burning or shocking the carbon off. A good high rpm run also is good at cleaning the combustion chamber.

Re: lugging-down "rattling" noise w/standard tranny
Ok. I'm going to try the water thing. Before I do, though, I want to
make sure I can somehow quantify your instructions. How slowly should I pour in the water? I don't want to damage the engine by accidentally going to fast, and I don't want to go so slow that it doesn't do any good. Should I remove the stock air intake tubing, to pour in the water, or is there another trick? Thanks!

I heard that you should use a spray bottle and just spray it in...

Re: lugging-down "rattling" noise w/standard tranny
Could be loose cat converter internals. Could be pinging. Could

Re: lugging-down "rattling" noise w/standard tranny
Bill, All,
While we're somewhat on the subject, I have an '03 TJ I6 that will provide me with bothersome "spark knock" at 2300-2400 RPMs on the highway in 5th on the flats. As soon as I accelerate, it goes away. Whassup with that? I've been using the same gas since I bought it a year ago and was advised by one of the mechanics to NOT burn 92-93 octane as it is not as volitile as 89 octane. Thoughts?
