So what do you guys think is better, a original motor or a rebuilt one?
my debate comes in here cuz my mazda dealer told me my warranty is comming to a end and i know him really well so he asked me if i wanted to blow my old engine to get a new one in. Weird thing is my car drives about 4months a year then i store it for winter its a 2005 80k km on it.

So what are the pros/con of each:

thx

 

So you are saying your Mazda dealer is willing to commit fraud in order to get you a remanufactured engine.

Huge FAIL

 

Yah haha

 

Are you asking if a rebuilt motor is better than a motor with 80k on it? Well I guess if the rebuild was done by a one year old monkey then maybe. And FYI, the dealer cannot get you a new motor, only a mediocre reman.

 

im asking shold i go for the rebuilt or not. i have a weird impression that rebuilt have less power in em.

 

I have weird impression that you are an idiot.

 

not a idiot just a guy trying to learn. but yah thx for being a ***

 

Well, I find it hard to believe your dealer specifically told you to go blow your engine in order to get you a reman from Mazda.

And if your story is true after all, well, that's just totally dishonest. That's the kind of behavior that would make it difficult for other honest users here to get their warranty claims for engines that died under appropriate circumstances.

Please do not do that.

I seriously hope you are bluffing

This

And you should trust 9krpmrx8's opinion as he has been through a good number of engines

 

he never actually gave his opinion on the engine:P
But he sure gave one on me haha

 

'cause you earned it

And he did give an opinion on the engine. It's just that you are not able to comprehend

To make it easier on you: many people have received reman engines from Mazda that were junk, while others were good. Impossible to predict which one you could get.

But at 80K miles and almost out of warranty, I would certainly take the reman engine.

 

If you were trying to learn you would research the topic and not start useless threads. If you read up on engine rebuilds, researched different builders, the Renesis engine problems, etc. You would be able to form your own opinion on the topic and you would realize how stupid your question is.

 

Why don't you get the compression tested, and send samples of oil for analysis? Then you'd know what you have now, and can make an intelligent decision on whether stealing a rebuilt is worthwhile.

see now thats better info even if your flamming i deserve it. but atleast you gave me info thx ill use search from now on :D

 

compression test gave me:

rotor1: 7,1
rotor2: 7,0
rotor3: 7,0
rotor4: 7,8
rotar5: 7,9
rotor6: 7,7

i dont know what they mean yet since i didint get a chance to read up on the info yet. and i plan on doing it. but my time is pretty used up lately.

And i did not get the oil tested.

as you can see im totaly new at this and trying to learn as i go.

thx

 

did they specify an rpm with the compression numbers? i think those numbers are useless unless you have the speed they were performed at. But all the numbers seem pretty much the same on each rotor, i presume "rotor 1,2,3 is" rotor1 and "rotor 4,5,6" is rotor 2. usually when the compression's crap youl get 2 low figures and 1 high figure.

 

If the Mazda dealership offered you to blow up the old engine to get a rebuilt engine, then do it. A rebuilt engine is like a new engine.

 

wow, you must be a really good friend to them, cuz that's fraud right there.

Well, the compression numbers seems fine BUT, if I were u, if I have this kind of "opportunity", I will tell them sure, go ahead. get the engine but DON'T install it back to the car yet, send it to some GOOD BUILDER to do a complete rebuild. then u install it back. boo yea.

 

Well, depending on RPM and vacuum readings - as well as altitude - those numbers might not indicate a dead engine. I believe Mazda will deem an engine bad when the numbers fall bellow the 6.0 value - i think (provided the aforementioned variables were at their right values as well)

well, again, provided you get a good reman

yeah, the whole story sounds too improbable.

Also, how would he manage to get the reman engine somewhere to have it built by a good builder? Thought the dealer would keep your car and install the engine there at their facility.

 

Get the rebuilt motor. Jeeese I can't believe this thread is real. What is wrong with you.

 

 

freedom of speech can be a dangerous thing

 

Are you sure about that? There are a good number of posts about problems with Mada's so-called rebuilts. Posts a couple of years back from a guy who claimed to work at Mazda's rebuilding facility did not inspire confidence, either.

If everything's fine, don't mess with it. Are you running premix or anything? Not trying to start up a war on the oil/premix topic, but it might help. I assume 1-3 is your front rotor, and with it being lower than the rear across the board(But still good), I'd try and make her last. If you've got something good already, don't fix it. You don't know what you'll get after wards.

But I'm also someone who would rebuild the engine myself, before getting one that I didn't know too much about it in particular installed. But that's my opinion, preserve what you've got now and make her last.
