Crushed ones, by the sound of things.

 

Just save your money and get a fresh motor.

 

lol i hafta find a engine rebuilt kit with apex seals...
and my friend at mazda is gunna rebuild my engine
for me :3

 

You don't listen very well, do you?

and wtf is :3? Are you a cat or something?

 

im jus sayin i got someone to help me rebuild my engine
with a rebuilt kit.... i dont get whats wrong with that....

 

This just keeps getting better...

So is your "friend" at Mazda going to use the same housings and rotors, even if they were scoured from the engine being "SEIZED"? How about the e-shaft and bearings? I'm sure other parts were damaged some how as well, so there is more to replace in your motor than just the soft water seals and hard metal apex seals - which is only a basic rebuild kit that doesn't have other parts like rotors and housings that would almost CERTAINLY need to be replaced in a seized motor - which is why people are saying you don't listen.

You need to tear the motor down, see everything inside, then a "professional" can make an assessment about "what parts" that your "rebuild kit" is going to need and how much everything is going to cost.

Also, I wonder how much your "friend" at this Mazda dealership knows about re-building rotory motors, since most everyone here agrees that dealerships have no clue about these cars. Is he/she going to do this "under the radar" at work? Fat chance that doesn't go unnoticed... and if it doesn't, what happens to your "friend" ... or maybe they realize with more parts to replace, they need to charge more $$$.

Considering you drove the car knowing it had a bad oil leak, you deserve to read the ENTIRE faq section before getting any sleep

 

Because you can't simply "rebuild" a motor that was killed due to oil starvation. A lot more than just the seals are damaged. As EVERYONE has said, you're 99.9999999% likely to need an entire new motor.

Read Nizzles' post. And Goodfella's post(I hope you know who he is), and bencb's post, etc.

Look, kid. I'm sure you're hoping to just skate right on past this issue, but you bought the wrong car for that mentality. I'm not trying to be a dick, but it is what it is. The FD has been this way since the year you were born, things aren't going to magically change for some dumbass kid who doesn't have the common sense to watch his fluids or the money to pay for a new motor.

 

Here's a link to different types of engine failure... I think most would agree, that aside from black carbon buildup (which your motor could have anyway), would be minor compared to a "SEIZED" engine.

I would read through most of that site as well Then ask yourself, "Do ya feel lucky?"

 

You'll probably need to replace a lot more than that. The irons and housings are one big additional expense. If you re-use those parts in so-so shape your rebuild won't last as long. Another point is that there are other parts on the engine that *should* be replaced now. If you cheap out and re-use many of those parts, you'll probably have new problems not too far down the road. Parts like wiring harnesses, oil metering lines, vacuum hoses, solenoids, FPD, etc.

Regarding who does the work: it's not uncommon for a less-than-excellent rebuilder to rebuild the engine and have a problem with the assembly process. Then you have to rebuild it AGAIN. Guess what, you still pay for it. Not to mention the durability of this rebuild.

Your friend may have the necessary skills and tools to do the job. But Mazda almost never rebuilds engines - they install reman'd engines instead. So your friend would be very much of an exception. If he hasn't done a rebuild before I would steer clear since there is a learning curve to doing rebuilds and you don't want to do this twice so he can learn.

It's the common experience of many here that the cheapest long-term strategy is to "do it once, do it right".

It sounds like you have some interest. Read the FAQ here and get as informed as possible. I'm not recommending that you go out and blow the budget for this rebuild, however you should understand why some people will spend a lot more and what that gets you.
