MS6 Engine Knock and or clicking noises. Please post here if you have it

Ok folks, it's seems it's that time again for me. Those of you that have been around a while know I was highly involved with trying to get Mazda Canada to fix the clunk.

Well, now I'm trying to get them to fix another issue, and I need to know of any threads concerning it that might have been already discussed

If you do NOT HAVE THESE EXACT SYMPTOMS, please don't post here about other noises you have heard.



Description of Noises

During Normal acceleration\Normal Driving conditions, that means NOT RACING NOT FLOORING IT, Not WOT, just driving NORMAL. :) Sorry but some folks definition of "normal" is not normal

Anyways, during normal acceleration. There is a knock, or clicking sound coming from the right ( Passenger side ) of the engine. From this point I will refer to that as ....get ready for this.... "the noise".

The noise happens in any gear between 2500 and 3500 rpms. Usually after going up a hill, or coming off of a hill. During the noise, the car does not accelerate, if you are quick enough, you'll see a puff of dark white smoke out the back of the car. Easing off of the gas gets rid of the noise, and getting back on the gas again the car will accelerate as normal again.




I have had this happen while just trying to go up a hill. Cruising on the highway at normal speed limits, I've even had this happen during cruise control by just by hitting the cruise control accel button to accelerate a little.

The problem is, of course that car doesn't do it all the time, and it's become very difficult to troubleshoot. I've searched around, and it seems there are literally hundreds of MS6's effected by this. I'm not sure of MS3's.

Guessing it was a fuel issue, we've replaced the high pressure fuel pump, checked the turbo, reprogrammed ECU, still no success.

After waiting 2 years for the problem to be resolved, they call me today and tell me to get premium gas....imagine that, I would have never of thought of it....DUH. And to try gas somewhere else. Unfuckingbelievable. And that came straight from Mazda Canada. I fear my dealer is headed into a circle of endless troublshooting unless someone higher up resolves this. I refuse to have them pick my car apart trying different things based on no idea where to start. I do have a excellent rep helping me.

91 octane is the highest I can get here. there are about 4 other speeds in my town, mine is the only known issue, but the others are driven by...how should I say it, less then the average auto enthusiast type....and women...sorry.

I can replicate the issue sometimes but allowing the car to get to 2500 rpms, then accelerate from there, not WOT, just normal. It usually happen as it hits 3k. If not, slow down try again and repeat. The trick is to be in a gear where she is hovering around 2500 rpms. And I'll go up a few hills to try it.

I've also noticed my fuel mileage is down quite a bit, and she's been down on oil.

I'm not sure how heavily involved I'm going to get with this. Fact is 3 Mazda's for me, 3 major issues, 3 strikes, and 3 times I have not sued. As far as I am concerned, the clunk was never fixed either. If this turns into another Clunk scenario, my patience are done, and I'm not going about this in the same manor as I did before. My health hasn't been the greatest this year, and I just don't have the time to waste on this.

Thanks for reading.

30,000kms on car. Issue started just 4 months after I bought it, Sept 2006.

I have the same "noise", the metal clicking/knocking sounds seems like coming from the glove box area, if that is the noise you are talking about, try checking for air leak, I had mine fixed and have not happened again for the past 8000 + miles, here are what needed to check:

1) follow the air intake, all the way to the turbo inlet, there should be a single clamp there at the join of the plastic intake to the turbo inlet, mine is completely loose, I has this problem since my car was 2K, I suppose my friend at Hofu forgotten to tighten it? or the heat from the turbo really lossen it? in any case I replaced the clam with a t-bolt clamp, if I remember right, it's a 3 inch clamp (not sure what is the mm conversion for you)

2) check the vacuum hoses from the air intake to the boost solenoid and again, from the solenoid to the waste gate, I suppose the heat may have something to do, the hoses is harden and so loose that I can move them with the clip on, so I replaced them with 4mm silicon hose.

While you are at it, might as well check all the IC hoses too, or replace the worm drive clamp with the t-bolt clamps, wouldn't hurt.

Boy, glad I did, that strange glove box "the noise" is gone, I hope is for good!

Good luck to you, but I'll say worth checking or replacing the hoses anyway, after all, it only cost me $6.00 to fix it!

interesting. I'll pass that on. But I don't think it's a leak, been there done before and it didn't sound anything like this. Besides, the dealer just dismantled the turbo, and I would hope they would have seen something like that.
 
I recall this happening a couple of times to me. Once going up a hill this was at the bottom not from a dead stop and going off and offramp slight uphill then at the end of the downslope left turn clik clik clik.

All these cliks as i can recall the gas pedal was not floored the offramp probably in 4th gear probably same at the start of the hill. Probably the same rpms u are describing.

This was prior to getting the reflash 4106E emissions recall and in dec 2007 i got them to check pcm for updates & reflash with latest calibration.

I havent really noticed the clicking partly due to the fact i now have a louder exhaust. But i have heard people say not to gas it too hard at a low rpm 2000-3000 but to downshift instead.

Im sure u have also heard of the latest fixes :

ROUGH IDLE, LACK OF POWER, AND/OR MIL ON WITH DTC P2177/P2187 (FUEL
SYSTEM LEAN)
Bulletin No: 01-022/08

I havent bothered with this one yet, i have spent waaaay too much time at the dealer with this car already. Goodluck keep us posted.

I am not sure if your problem is similar to mine, but I have been afflicted with a noise since about 5,000 miles (interestingly enough around my first oil change). My noise is MOST evident at start-up and above approx. 2,500 rpm. I would call my "noise" similar to sounding like a chain dragging across the ground as you drive. A "ringing" sound that is definitely heard from the right side of the car. Right side, outside, with the hood DOWN. Hood up, too much engine noise. Also, with windows down, it is quite obvious.

Similar? Could the oil change have dis-lodged something?

I have the same problem. Told the dealer but they say since there is no code they can do nothing.....WHAT BS!!! So I am gonna take it to the dealer and force one of those lazy asses to go with me so that they can hear all the crap I am hearing lately. I may even give this thing up and go back to an RX-8 just because of the fact that I will have a 100k mile warranty.....

I am also hearing a noise that sounds like a bad shock or axle. This car only has 43500 miles on it and it is not sounding good. I love this car but hate all these issues......

not the same issue
 
so far they told me to try different gas..and actually thought they should ask me if I was putting in premium gas.... I mean come on, I know there are idiots out there that might not but this is not exactly my first Mazdaspeed here.

So, as expected, issue still not resolved.
 
I am no where close to being an expert but clicking noises usually mean somthing with the valves. may want to get them looked at/ adjusted.
 
might want to pull the intake manifold and look for any sign of a leak by the injector seals - this is a new theory some guys are speculating about with some recent happenings to a few guys on MSF
 
Im pretty sure the clicking noise has nothing to do with a turbo...because i have an auto 6 and i have the same noise....lol
 
A few members at 6 club have had their timing chain tensioner replaced. Because I can't link to the other forum here, this is what the op said:

"I am starting a thread regarding a problem that seems to be getting more common as these Speed6's are getting a little miles on them. It seems that the Timing Chain Tensioner in this car has the tendency to fail. Mine went at 49XXX miles and the dealer Screwed me around until I was out of warranty so mine did not get repaired. I would like to prevent this from happening to anyone else. The exact problem can be described as a rattling/ticking sound coming from the left corner of the valve cover (where the chain is.) It get more audible as the car is warmed up. This is was differentiated it from the VVT TSB we all are aware of. You can hear it in the cabin at idol pretty easily.

I had mine looked at by an independent mechanic and he diagnosed it as the Tensioner, but he did not have the tools to fix the problem. It requires three special tools from Mazda according to ALLDATA.

If you have had this part replaced by the dealer due to failing, please post here and we need to start a list. Possibly we can help others get something done about this problem with less fuss from the dealers if we have some proof that it is a somewhat common problem. "
