new shortblock less than 10000 miles????!!!!

[bhstall]

A couple of weeks ago..I was coming to a stop and when I started to push in the clutch it started pulsing violently against the bottom of my foot....My first thought was something broke it the clutch....coasted in a parking lot and figured out that with the clutch all of the way in or all of the way out there was no pulsing and the clutch worked normally...so I drove about a mile back home.....called roadside assistance and towed it to the dealership.
They diagnosed it as the clutch...replaced it...It did not fix the problem...they called and told me it was a bent input shaft in the tranny and that it was caused by abuse and Mazda might not cover....ridiculous...I was coasting to a stop when it happened!!!! They(dealer) told me they were waiting for a call back from mazda...the very next day they call and tell me that Mazda(field engineer) diagnosed it as a bent or broken rod and they are putting a shortblock in it.....sounds crazy to me.....anybody have any thoughts on this?.....Ive never had a problem with the engine.......it ran fine???!!

many times, the cause of the blown engine/damage is not done when it blows, but instead before. You may not have been abusing it when the pulsing started, but abuse before that instead.

sigh...it happens...was it after a long drive?

 

[bhstall]

no a short 5 min drive

Is putting in a short block normal or do they usually change the whole engine??By the way i have more info from the dealer now..they say at tdc the #4 cylinder is .733" short compared to the others....they say it is due to an injector leaking down...not abuse(now)...mazda is going to cover...I had the car in to the dealer a couple of weeks before this happened for backfiring "loud" between shifts ....they couldnt reproduce the prob...and said it could be normal....Im not sure if this could be related or not?

 

[GoFast]

sounds normal to me. If the heads are ok, there is no need to replace them.

tsk, man!!! thought i'm problem-free with this car but something keeps popping up! i'll cross my fingers and thanks for the info.

 

[Wagonbacker9]

sounds related to me... injector leaking = lean condition in cyl 4 = backfire = bent rod....

thats ok mine launched a rod out of the block at 5177 miles on it. had just shifted to second 2k rpm. was in my neighboorhood luckily. ended up have to get a whole new motor.

to op, did you have any mods when you brought in the car?

I think i have the same problem, i get pulsating when lightly on the clutch and once i press it in, the noise goes away. The pulsating came after random misfires happen.

i brought it in yesterday, and the dealer insisted it was a clutch issue and if a mazda rep comes and look it at and there was no problem or they refuse the claim i would be charged $700+, what bs. They kept saying that mazda will most likely refuse the claim cause i had some mounts ...

Its weird too, i would think if it was a bent rod, that the noise and vibration would still be there even if the clutch is pushed in?
