Title: Engine Noise - Any Guesses?
Post by: Cunning Plan on November 04, 2013, 08:49:13 am
Okay so the old Cherokee at 149,000 has a little noise issue first thing in the morning, where on idle it sounds like a rattling chain-type-noise.

After a day at work, coming back in the evening it doesn't seem as noticeable and when the engine is warm, you cannot hear it at all.

I am assuming it is one of the belt-pullys with a worn bearing? (http://www.mkb.cc/forum/smileys/huh.gif)

Any other suggestions? (http://www.mkb.cc/forum/smileys/pokey.gif)

There is no timing belt or chain on it as it is an OHV engine, so I know it isn't that. (http://www.mkb.cc/forum/smileys/chiny.gif)

Unless there is a small chain connecting the cam to the crank and it is driven by that instead of a direct drive.

get a long screw driver or piece of wood,
 and place it on various parts of the engine,
 with ya earole on the other end and try to locate roughly where the noise is coming from..

Blaady hell, my gear hobber at work has a less intricate set up than that!

Yeah, you need to localise this a bit more and go from there. Do just make sure someone hasn't left anything loose in the bay though.

I had a really annoying intermittent vibration in my car in the bay. Ages and ages it took to find until one day I noticed that the engine cover was just touching the inlet manifold and at certain RPMs it would just be enough to tap away making a vibration noise.

Are you sure it's from the engine bay? I had a loose bit of exhaust heat shield on the old Mondy that I first thought to be a nasty rattle from the engine..

It didn't seem to be protecting anything so I just tore it off.

There was a rattling from the first exhaust support mount / bracket that had corroded through. I took it off and it's on my 'buy-list' to get and fit a replacement. This is defiantly from the engine though (http://www.mkb.cc/forum/smileys/chiny.gif)

I took a video first thing this morning so you can hear it too. It is more noticeable from the bottom of the engine when I move the camera down. It's almost a cross between a squeak and a rattling chain. (http://www.mkb.cc/forum/smileys/chiny.gif)

Post by: Roadkill on November 05, 2013, 03:06:37 pm
Going by the position you were when you could hear it most it definitely sounds like it's coming from the pulleys.

If it's rattling like that I'd *guess* that it's not a major load-bearing pulley (ie not the cam or crank) . . . My guess would be vacuum pump as it's a dry-running pulley.

The other likely candidate is the oil pump but that's below the oil line so would probably be leaking oil quite badly.

 . . . Or it could be none of the above.

I sometimes use a 3/4" piece of rubber hose to find engine rattles . . . like how Art said but being flexible you can get it "in" further . . . you'll need to press the end hard up against the engine, though, as all you'll hear otherwise is the air turbulence in the engine bay (Think stethoscope) - the other end tight over your ear.  It helps to block your other ear, too.

All auxiliary-drive pulleys are open, driven by one serpentine rubber belt as shown below:

Okay I made sure I had a look at this yesterday.

(http://www.mkb.cc/forum/smileys/mechanic2.gif)

Quoting: art b
you should remove the ancillary/serp belt,


I went for this first and it totally confirmed that it is one of the pulleys driven by the drive / aux belt, because as soon as I took the belt off and ran the engine, it was the quietest it has ever been.

(http://img.photobucket.com/albums/v282/v8_nate/Jeep%20Cherokee/ScreenShot2013-11-10at120028.png)

I put the belt back on and it seemed a 'bit' better, but I am not sure if that was because by that point it had warmed up and the noise is always quieter when it's warm. So, I went back out first thing this morning to start it again and the noise is still there. (http://www.mkb.cc/forum/smileys/down.gif)

Whilst doing some exploring around the engine, I did notice that the water pump is seeping a little bit, so I'll have to replace that, hopefully at the same time as replacing whatever is making this noise as I will have most of the front-end apart. (http://www.mkb.cc/forum/smileys/sad2.gif)

I have to say, it sounds like it is coming more from the fan pulley or the centre of the selection of pulley-wheels. Although, it's just too hard to tell exactly with all the noises of the engine. I did try putting a screw-driver against the non-rotating parts of pulleys I could get to, but it didn't really help. (http://www.mkb.cc/forum/smileys/sad.gif) Another issue is I cannot put the belt back on to run certain components at a time to narrow the issue down because the belt runs literally everything, it's a beast of a belt. It's either all on, or all off.  (http://www.mkb.cc/forum/smileys/chiny.gif)

The fan is a thermal viscous fan and I am wondering if anyone knows if they usually have the noise issues mine has? (http://www.mkb.cc/forum/smileys/dontknow.gif)

(http://img.photobucket.com/albums/v282/v8_nate/Jeep%20Cherokee/ScreenShot2013-11-10at115715.png)

I think I will end up having to do this, take everything apart, except the fan pulley, then run the engine again, if there is no noise, then it must be the 'bimetallic' spring in the viscous fan.

(http://img.photobucket.com/albums/v282/v8_nate/Jeep%20Cherokee/ScreenShot2013-11-10at120649.png)



I did find this in the manual, although the fan-blades seem fine, I couldn't spot anything loose.

(http://img.photobucket.com/albums/v282/v8_nate/Jeep%20Cherokee/ScreenShot2013-11-10at120203.png)


I drove to Norfolk and back Friday / Saturday morning and it's fine (touch wood), but it's just annoyingly noisy first thing in the morning. Also, if it is the fan, rather than it breaking and the engine over-heating, I think I have to try and fix it.

Yah, I remember your thread about it and that was a LOT of work (In fact, I even looked the thread up to find what your issue was before posting this thread).

I am going to call Central Auto's tomorrow to try and get a price for the tensioner. If it is not too bad, I might just replace it anyway along with the water pump O-ring seal / AND OR / water pump (dependant on cost).

As I say though, I am sure it is more from the centre of the engine than the left (as you look at the engine bay, which is where the tensioner is). (http://www.mkb.cc/forum/smileys/chiny.gif)

This isn't bad advice really, because as you say, it isn't effecting the engine performance and it is just an annoying noise on the first cold-start. Once warm, it just sounds like a old-skool Diesel / tractor as usual (http://www.mkb.cc/forum/smileys/cowboy.gif)

No I didn't (http://www.mkb.cc/forum/smileys/sad.gif)

The guys on Jeep-Club suggested to spray some WD40 on the back of one pulley at a time to try to eliminate good pulleys and hopefully find the source of the noise. I will try that next and if that does not work, when I am replacing the water pump O-Ring seal, as I will have to take the drive-belt off to do it, it will give me the opportunity to give each one a wiggle.

I have tried this and it just sounds the same: Rattley-chains in the morning, which is louder when it is cold outside, then fine when it is warm or on second / third start of the day.

Has anyone got any idea how I can find out what size water pump is in my engine without taking it apart which will mean draining the system, then once I know which one it is, I will need to put it back together with the leaking pump, fill it back up with AF and coolant, bleed it, go and get the new pump, then do it all over again to fit the new pump.  (http://www.mkb.cc/forum/smileys/down.gif) (http://www.mkb.cc/forum/smileys/sad2.gif)

There are apparently two choices of pump for my engine - 70mm and 76mm. They are both special order and non-refundable, so I cannot buy both and take back the one that does not fit. (http://www.mkb.cc/forum/smileys/chiny.gif) (http://www.mkb.cc/forum/smileys/smirk.gif)

I wouldn't have thought the water pump would be making this noise.  Water doesn't lubricate so the noise wouldn't go away once the engine warmed up.

Unless you can be more sure I'd run it another week or two and just periodically give it a visual check-over to make sure nothing is about to fall off.

I don't think he thinks its the water pump, he did mention somewhere further up there that the water pump is leaking, so I guess he's going the whole 9 yards and replacing that, plus the gasket.

As, to me having no heard the video (which I missed before) sounds like a shagged bearing. Now that could go on doing that for ages, or eventually seize up solid, but for the time being, as long as you hear it, you know its moving! (http://www.mkb.cc/forum/smileys/tongue.gif)

While thinking of eBay, check out the option on there, as EuroCarParts are registered on there and sell their bits for cheaper through there. Also you'll get the eBay guarantee, so in theory could send it back.

I don't mind doing another coolant change as the cooling system on the Diesel 2.5 needs a lot of looking after, so it should be beneficial. Although, it is very annoying as I only did it a month ago or so (It gets two flushes a year).

Dude, I fecking love you. (http://www.mkb.cc/forum/smileys/SUCK.gif)

Called ECP this morning and ordered both pumps for £50, plus they will accept back whichever unit is incorrect! (http://www.mkb.cc/forum/smileys/up.gif)

However, they did explain that they have a similar policy as CAS, where if the parts are not in 'company stock' and they have had to order them in specially, they cannot return them to their suppliers unless they are faulty parts, not if someone ordered them incorrectly, which in-turn means I could not simply return the wrong one. I can appreciate why, but it isn't that helpful when you're in my situation. (http://www.mkb.cc/forum/smileys/smirk.gif)

But, the ones ECP have are from their 'stock', so, I'm collecting them tonight and I'll fit one of them tomorrow morning, give the cooling-system a flush and re-fill and hopefully eliminate the pump-seeping issue. I will have a further play with other pulleys whilst I am at it to try and find this rattling noise.

I have an idea to attach each pulley in-turn to the crank until I find the noisy one, however, I am not totally sure how. Perhaps some heavy duty cord? Not sure.. (http://www.mkb.cc/forum/smileys/chiny.gif)

I reckon once you have the main serp belt off and you try spinning a few of the, you'll see what is what, and what seems knackered.

No worries about ECP, they've been more than helpful to me on several occasions. Used to use a small outfit at the end of our a round but a new guy started running it and it promptly went broke. Haven't had a single issue with ECP.

Called ECP this morning


Not overly impressed with ECP. I arrived to pick them up on Friday after work to be met by a guy on the front-desk who I had to tell 4 times that I was there to pick up a water pump. The conversation went like this:

Me: "Hi I am here to collect water pumps for a Jeep Cherokee"
ECP: "Ok"
Me: "The registration is X"
ECP (typing away): "Okay Sir, so you are here to collect oil pump."
Me: "No, water pumps"
ECP: "Okay, what car is it"
Me (thinking WTF): "It's a Jeep Cherokee"
ECP: "Washer pump for a Jeep Cherokee"
Me: "No!!! Water Pump for a Jeep Cherokee, I called earlier, there should be two ordered for me, I spoke to Robin, is he available to speak to?"
ECP: "Water Pump, oohkay, what's the vehicle reg?"
Me: "It's X"

Sure, it could have been an off-day for him or I could admit that perhaps he didn't understand because of how I said it, but seriously, dude (http://www.mkb.cc/forum/smileys/banned.gif)

Anyway, after that, all I wanted to do was get in the car and get on the road to travel to Norfolk (where all my tools are) before the traffic gets heavy, so I did not check the boxes.

The next morning I got up to change the water pump, but experience told me, before everything is apart, I should check the boxes to ensure that they are the correct parts. The boxes were extremely damaged, I think both of them had been used as footballs. Not filling me with confidence, I decided to check for damage and after looking at each pump I noticed that neither had the vital O-Ring seal included, even after specifically asking EuroCar Parts (<for the benefit of Google) on the phone before I ordered if they included the O-Ring seals, which I was given the response of 'Yeah they should do... yeah'.

To be honest, I could take a small amount of the blame as you could say I should have checked whilst at ECP, but after dealing with the challenging chap on the front desk and after being told that they would include the seals, I just didn't think of it at the time.

So, first thing was spent driving into Wisbech to the Hydraulic engineer to get some seals made. (http://www.mkb.cc/forum/smileys/rolleyes.gif)

Fortunately, they were open on the Saturday and made some up for me within minutes. (http://www.mkb.cc/forum/smileys/clap3.gif)

Then, in an attempt to get at the water pump, I took most of the front end apart, but I still could not get at the bolt that was at the tightest angle.

(http://www.mkb.cc/forum/smileys/mechanic2.gif)

I always start with the hardest fixing first, as you know if you can get that out, you can do the rest, otherwise you disturb the seal by loosening the easy ones, then discovering that you cannot get to the hardest one (http://www.mkb.cc/forum/smileys/mad.gif)

Bearing in mind that it is not a leak, it is a 'seep', I thought it is not urgent and I would have to suck up the wasted hours taking everything apart, to put it all back together again and fill it back up with coolant, then bleed the system, without actually repairing the water-pump seal with the intention of attempting it again with an adjustable-headed ratchet spanner. I did not really have a choice as the Cherokee is my daily driver and I needed the car for work (http://www.mkb.cc/forum/smileys/confused.gif)

So the plan is to fit the new pump when I am confident that I can get the bolts out.

HOWEVER, I noticed, especially this morning since it was 0-2 degrees and the noise is usually at its loudest when it is cold, the engine noise had gone (http://www.mkb.cc/forum/smileys/huh.gif) It sounded completely normal (http://www.mkb.cc/forum/smileys/confused.gif) (http://www.mkb.cc/forum/smileys/dontknow.gif)

So I am assuming, it was something un-important rattling around, perhaps near the radiator where it expands and contracts with heat.  (http://www.mkb.cc/forum/smileys/huh.gif)

Did you not do the hammer test first?

You know, you go round the various areas where the noise is hitting bits to see if it stop/gets worse/goes bang? (http://www.mkb.cc/forum/smileys/tongue.gif)

Regards ECP, thats a shame. I know they don't employ the most knowledgeable staff, but my local one has two or three guys that are ex-dealership parts people (particularly Ford) so know a few things others don't, very helpful with my Focus at least.

Again, the parts getting kicked around, can't say I've had that, but I would've personally rejected them on the spot or at least gone over the contents there. There is a sign at my local one that tells the clerk to check the box with the customer before signing for it.

Good call on the trying the hardest bolt first! So many situations where I wish I'd adopted that approach before getting stuck! Guess it could be a front off job so you can get access to it. That or get it started with a cold chisel? (http://www.mkb.cc/forum/smileys/tongue.gif)

Okay engineers, a question for you (http://www.mkb.cc/forum/smileys/stir.gif)

The water pump pulley-wheel is fixed to the pump with x3 Torx or Spline screws, I can't remember which. It looks a little like this:

(http://img.photobucket.com/albums/v282/v8_nate/Jeep%20Cherokee/_12.jpg)

All of them look a little corroded, so I am considering removing the water-pump from the block, then drilling out the pulley-wheel screws and replacing them with nuts and bolts with a good allowance of locktite.

Are there any issues with me doing this? (http://www.mkb.cc/forum/smileys/dontknow.gif)

I should point out that I need the pulley-wheel to go on to the new pump.

No issues, providing you have clearance for the longer bolts.

Seems overkill if they're just a bit corroded, though . . . could end up being an unnecessary can of worms.

Can you not just re-tap the holes and wire-brush the bolts ?

The bolts / screws are the problem, I think I will have to get the pulley in my vice and drill it out as the head seems 'fragile'. One of them is not rounded though.... Yet! I noticed it seemed to be giving and not in a good way, so I stopped attempting to take the pulley off in situ with the engine.

Then I thought that bolts and nuts would be much more secure and better should I have to remove it again (http://www.mkb.cc/forum/smileys/chiny.gif)

Fair enough - so not just corroded but actually pretty fooked.

Yeah, go with bolts, nuts and spring washers . . . I'd suggest you'd NOT want to use Loctite . . unnecessary, IMHO.

Decent set of spring washers, jobs a good'un.

Haven't got any photos of the final install, but when we upgraded the cooling fan and radiator on the Mustang we just pulled out some some stock ?UNF bolt and spring washers.

I was thinking about finding a pulley to have as a backup in-case the drilling out of the screws does not go to plan.

I found the exact same pump for the same engine on eBay, yet interestingly, the fixings are bolts:

(http://i.ebayimg.com/t/Jeep-Cherokee-WATER-PUMP-2-5L-Diesel-1999-XJ-VM-/00/s/OTYwWDEyODA=/z/CbQAAOxyuDpSHUtS/$T2eC16Z,!)YFIcJ1-uroBSHUtRtio!~~60_58.JPG)

Which makes me wonder if a previous owner had the pump off at some point and replaced mine with screws rather than bolts, or the other way around. (http://www.mkb.cc/forum/smileys/chiny.gif)

I'm getting a bit lost in this, using terminology such as screws and bolts.

So your pulley is bolted on to the propellar shaft of the pump. That is via threaded holes on the shaft, with no nuts.

You're planning on taking the whole pump off, drilling out the bolts, then replacing the bolts that have been drilled out with bolts and nuts?

Is that right?

Ah sorry dude!

Right, when I say, 'screw' I mean a bolt with a spline-type head.

I cannot find a really good picture of it right now and I can't take one (in the office), but it is quite similar to this Torx one:
