New engine at only 19,000 miles

Yep, that's right. This tops off the tranny rebuild we had done at 10,000 miles (SEVERE grindage).

It began as a simple thing, really. I took the car in for delayed starting. No, this was not the typical dragging start that is related to the battery. The starter cranked the engine at normal speed. It was taking about 10 seconds of cranking to start. Sometimes it wouldn't start, but it would start right up on the second round of cranking.

A simple fix, I thought. I figured maybe the spark plugs were getting gummy. I am friends with the head Mazda mechanic at our dealership here. He checked the plugs, but they were fine. Out of curiosity, and perhaps because the plugs were already out, he checked the compression on the motor. He said Mazda minimum standards were that the compression be at 98% on the rotors. Mine was diagnosed as 84% on the front rotor and 74% (

) on the rear rotor.

The service manager called Mazda about the issue because my poor car's motor was quite worn at only 18,992 miles. It took much deliberation, but they decided to warranty the motor (as if they had a choice

). They were asking questions about modifications to the car from exhaust to even if it had after market wheels!!!

Anyhoo, I think my 8 will be one of the poor damned souls, like many of the FDs.

I am by far not complaining. I love my car, but if she is going to need engines replaced in that kind of time frame, I will be forced to get rid of her.

Just a word of warning for you guys, if anything like the problems I was having happens, get the compression checked. Hell, I'd have them do it anyway, especially because my car was running just fine once started (it was idling a little rough though). We'd have never known, if it had not been for my friend. Who knows--the engine prolly would have worn completely out just out of warranty. That would surely suck.
 
Oh, and in my city there have been NUMEROUS auto RX-8s that have needed new engine and the more miles people are getting on their MT's, the more are rolling into the shop that need engines. *sigh* I had such high hopes for the Renesis...
 
Wow - So glad I went for the 350z instead of the RX-8.

My main reason was reliability. Rotary engines don't have the best track record for longetivity, whereas Nissans 6-cyl (VQ?) has been used in alot of their cars for quite a while now.

:edit: - oh, and hey diane, haven't seen you on here in a long time - nice to see you're still around. you're good stuff

im lucky so far. Ive got 23k on mine and its still on the original motor.....lol, sounds kinda funny saying it like that. My protege however, is on its 3rd motor and i can pick it up at the end of the week with the new tranny..it only has 55k on it.
 
My pro is on it's 2nd engine, but I won't blame mazda 100%, 11psi on a t3 ....

... man I miss that feeling

The nissan is fun, but it's one of those cars where people are ready for it, and worse - I've got other z's to deal with, not to mention the new mustangs, gto's, and a bunch of little johnny ricers. The protege, total sleeper - which in and of itself was alot of fun.

I beg to differ, my 1980 Mazda RX-7 has 288k miles on it when I drove it to the salvage yard for severe rust issues and the motor smoked bad at startup. It just wasnt worth the rebuild at the time.
 
So much for engine of the year.
I wonder how long it will take mazda to realize there are good reasons why no one else even bother with rotory engines
 
I am sure yours should be okay. Just make sure your car gets every little maintenance program done to it (TSBs, flashes, ect.) Our car was the demo car and she didn't get any of the flashes or other work done to her. Hell they didn't even change her oil and we bought her at 4,500 miles!!

Thanks! Oh, and we are already considering a trade on the Z...maybe when we get the note paid down...:(

(lol)

you guys with the turboed pro's should expect that though. :D I would have expected it if we put the GReddy kit on the 8, but i am glad we didn't yet. We just bought a house and that's taking all our money. :D

lmao!! yeah, my friend who's a Mazda mechanic said Mazda's gonna kick themselves in the balls for actually allowing the engineers who spent all those hard hours off the clock developing the Renesis to convince them to give her another go.

But seriously, the FDs in Japan (post '99 w/the turbo redesigns) were said to have been more reliable than the US spec FDs. its just that the FD was pulled from the US market before they corrected the issues. I believe in the fact that the first years of a new model will have hiccups, but jEEz--a new engine for mine already?1 I don't even think the FDs were such a rush engineering job.
 
lol - I'm getting personalized plates for mine - my choices in order of preference:

MICAHZ - self explanatory
PUREVIL - would be perfect, but with my luck I'll get a bible thumper cop
101010 - HHGTTG reference (it's 42), also highly open to misinterpretation... evil grin
FREQNHZ - "Freakin Hurts" - a less obvious geek reference I'm still considering

My friends however recommended the following: YEPIDID, CUZICAN, IN DEBT, SOBROKE, NVWSSV, and the ever popular 8INCHES.

The only one I would consider from my friends is NVWSSV.
 
Heh... Seriously, the problem with the Renesis is not the design, nor the design of rotary engines in general. A friends 1975 Suzuki RE-5 (Rotary powered motorcycle) is still running PERFECTLY with 290k (On a bike. Yes, a bike.) I've seen many FB's and FC's into the 200k mark with no problems.

Typically the problems spur from either Mazda pinching pennies durring production, or owners pinching pennies, regarding care of the cars. Or people just plain driving them like they don't have an upper limit. Sure, it feels like it doesn't, but seriously, it does.

The design of the rotary engine is terrific, really, and in conept and in practice they DO work well, except when Mazda's bean-counters get in on the action. Bastards.
 
Man, and I was here really thinking about possibly getting an RX-8. I drive too much to need a whole engine and I absolutely despise my local dealer service dept...

So wait, are there more problems for auto vs manual?
 
I've been depressed since i read this last night, i am dead serious. Not that i would be able to afford an RX8 any time soon, but just LOVE that car so much in all its aspects, that it just hurts. As if i got cheated on or something :(

I would still get it. I love the fact that mazda cars have a distinct character. They need attention, and can be in different moods. That's why i am a fan

you need a new engine why? because of the high mileage?

Nah, I'm just saying that I need something reliable because I drive a lot. I've already covered 85K miles. I would've had 4 engines by now if I had an RX-8 :D
 
guys, dont be detterred. not ALL rx-8's will need new engines at 19K. unfortunately for diane, she got a bad seed :( .

btw, diane. i think we bough the same car, lol. mine is a demo aswell. it has 6K, auto, and its black. i copied j00!!

also, i know nothing about lawncare. its just an inside joke that has to do with the fact that im mexican.
 
^^^I was just about to mention the same thing...I find it funny that everyone is all up in arms over one RX-8 needing a new engine at less than 20K miles. The fact of the matter is, she has an early model with an early build date I'm quite sure, and if you go to ANY message forum for a particular car, you'll find plenty of replaced engines and trannies.

It's the facts of life. There will always be a few bad apples. I'd actually be happy about getting a new engine if I were you diane. Just as long as they don't put a rebuilt or salvaged title on the car. Shoot who knows how those demo miles went for your car.

On another note, I just turned over 12K miles, I've had the car since late August, and I've had zero issues.
