Possible motor failure?
OK.... Just got my 8 2 months ago...
to make a long story short, the other day i decided to do a burnout. I lit the tires up for maybe 4-5 seconds and parked. When i had the car in neutral i noticed a knocking noise. My heart dropped. I shut down let everything cool off. turned it on and hour later and it was still knockin in nuetral.. So i drive away, when i put it in gear and drive it doesnt knock. but now it grinds 3rd gear bad and when im cruising and put it in 6th and let off the clutch it grinds while im driving... so keep in mind it only knocks in neutral when reving the motor, it grinds 3rd gear and grinds all of 6th after the clutch is let out... what could my problem be? I brought it to my dealer on friday and im waiting until monday to follow up... Let me know what i should be expecting... My 8 is bone stock... just did an oil change 2 weeks ago.... Help me out thanx in advance..... |
what year and model?
where are you? you give no info. beers :beer: |
Sounds more like a clutch/tranny failure than an engine failure.
|
woot, clutch bearing :D
|
sounds like a transmission issue to me as well
this "knocking".. where is it coming from? |
Don't know bro, as others have said it sounds more like a transmission/clutch issue. Keep us posted on the results.

the knocking is comeing somewhere from the motor... its wierd though how it only knocks in neutral... keep the feedbak coming |

"i decided to do a burnout. I lit the tires up for maybe 4-5 seconds"
That will do it...... |
if it occurs only in neutral, that tells me it's a clutch/tranny issue. If it was the motor, it would happen at all times, I'd imagine.
|
ya sounds like a tranny problem
|
yeah sounds more like a tanny issue possible a throwout bearing possibly not sure and when u say grinds all of 6th u mean while ur driving constantly a grinding/rattling noise?
|
yeaaa while i drive in 6th its a constant grind/rattle... im gonna call the dealer in the morning and see what happends... just hope its not a motor problem.. and i hope they cover everything....
|
hhaa i called the dealer today and they put me on hold for about 5 min. they came back on the phone and sed hold on there going to check the part there ordering for the car... Im pretty sure their going to need to order more then one part. So then she sed ill call you back in 15 in with the exact part and they never called back....
keep in mind they havent given me a loaner.... Tomorrow i will call again and hopefully theyll provide me with more info....Im going to ask them to check the throw out berring... but do u think they'll start asking questions if i tell them to check??? lemme know guys thanx fro the info..... |
yeah they need to tear it down and look.....it seems like sort of the same thing that happened to me took 27 ddays to finally fix my tranny was getting a grind in all my gears except 2nd and 6th under load when coasting in gear went away....oh and they did not give me a loaner the whole time....not very ghappy
|
1-why wont they give you a loaner when its in the warantee if your car is down?
2-is it because of your age (one would assume from the stupid i did a burnout comment) 3-if your local in NY you should have contacted on of us in the Northeast section or cross posted so we could help you out 4-try coming out to the meets we hold weekly....you might get educated on what you are driving 5-where did you take the car for service because i hear nothing but nightmares from westchester and bronx dealers 6-mileage? 7-year of car? 8-new or used? |
^^ Oh, come on - you know you did a burnout when you got yours... :)
|
tires are expensive....i aint that rich!
|
ok.... i got the car used from a hyundai dealership in westchester... they offered me 100 thousand mile waranty 10 years at a madd good price... its an 04 when i bought it it had 55xxxx miles.... Im 19 and everytime i metion a loaner car there like we dont have any in at the moment... My mom has to sign for the loaner but this time they were like no we dont have any but will call u as soon as one come in... 4 days later they havent called me. Im about to get on the phone with them right now so ill keep u guys posted...

please stop. you do not have a clue. beers :beer: |
knocking in a rotary can be a sign of bad/spun bearings, however it would happen anytime you get in the 1500-3000rpm range and not only in neutral, but most pronounced in neutral. Given what I have seen of the renesis engines I have torn down, the main bearings are not holding up well due to selection of oil recommended by mazda even when not abused, so I can certainly see a medium mileage engine dying a spun bearing death when undue stress is put on it.
That said, it will be difficult to tell if it is the engine or trans, until someone examines the engine oil for copper fragments. |
