car goes boom(pics)

[blackmica08]

well what can i said my beloved POS mazdaspeed3 went boom boom boom, it happened saturday afternoon me and the wife getting out of massage envy which is 4 blocks from house we go through a stop sign nothing happens, next a four way stop, 1st gear all good as i engaged 2nd gear not even close to 3500 rpm we heard a big boom and i felt like something came off right off the bottom of the car, looked at the rear mirror a cloud of white smoke and the car shut off. called the tow guy and as the guy lifted the car oil pour into the street like water from a bottle. this morning i snapped these pics, the piston pin came loose and open four holes, one of them being the pvc, the oil pan and two through the block. the tech guy said that the clip that holds the piston pin slided out and cause this whole mess, he also told me that this has become a problem with the speed3s, that theres no way that clip can hold that piston pin. im the third car i see in the dealer with a blown engine due to either weak rods or piston pin problems. new engine has been ordered.

they covered the costs right?

and this has nothing to do with the larger turbo or increased boost??

^ +1 sorry for your loss. But I dnt think that would be considered a POS

 

[mckraut]

If the dealer covered it, I'm quite surprised.

 

[Speed3Rookie]

It may be covered until the rep does their inspection.
Good luck with it.

If the clip that held the wrist pin in failed there is still not enough room for the pin to slide out enough for it to fall out or even come out of one side of the piston.

wow, this guys is BRILLIANT... lets put an extra 100+ horsepower in a car, and have it blow up and call it a POS... your a bright one...

where can i get an education like yourself

is your sig up to date?

so you were running a Copp AP flash with a GT28 turbo? That might have had something to do with your engine failure.

first you can go **** yourself, 2nd i was out of boost when it happened and even the tech told me that it had nothing to do with boost, last week a stock mazdaspped3 blew a rod through the block, and no im not paying for s*** is all under warranty.

i turned my boost down to 17psi and everything seen right, short and long fuel trim were within parameters, no knock at all and i had upgraded the fuel pump, now im running a gt3071r turbo.

If your dealership is honoring your warranty with those mods, I am going there from now on.

i really don't think it has anything to do with the wristpin. its just not logical or plausible in this situation. i am betting once the engine is apart it will be an apparant rod failure and the wristpins will be intact. the pictures indicate that a rod snapped at or near the crank, which a wristpin failure or clip failure would not cause. a wristpin clip failure at worst would allow the wristpin to slide back and forth horizontally and scrape the cylinder walls apart.

either way, it does not matter, since mazda is covering the engine under warranty. thats definetely good news for you.

just because it didnt blow under boost doesn't mean it wasn't cause by your mods. If your dealership is honoring your warranty with those mods, I am going there from now on.

Oh ok, missed that then since the OP was editted.

wow, now you edit your post to say that you weren't calling your MS3 a POS....


and running 19psi on with that turbo will wear the motor faster than what it should... just because you weren't in boost when it happens doesn't mean your modifications and higher boost didn't lead to the problem.

And grow up, i was just mad for your calling the ms3 a POS... no need to get defensive.... And their is NO way you can convince me that your mods had NOTHING to do with your motor throwing a piston

is still a pos, go to the other forum and you will see how many pos speed3 had blown up, the fact is mazda **** up in the design of the engine, that was exactly what every mazda thech that i know is saying, what about all the problem with th smoking brand new turbos which sometimes had to be replaced twice, aint that a POS DESIGN.

I dont think mazda designed the turbo and that it was contracted out or that sounds logical to me anyways. Now the motor is another story....

hey ken waz up man, theres a mark on the piston pin which the tech told me that the pin slowly slipped through the clip, the clip came off intact no damage at all.
