So recently my 2010 Rx-8 just died in a Walgreens parking lot and would not restart. I had to towed to Mazda where it was determined that my ignition coil needed to be replaced along with the spark plugs. The service technician recommended I do a compression test and I did and the results have me worried. Roter 2 came back with good results, Roter 1 however compression levels were: chamber 1 630, chamber 2 660, and chamber 3 660. This is all a little greek to me. I'm a 40 year old woman that bought my first Rx8 in 2014, she was a 2009 1 owner with 17,000 and absolutely perfect. It was a childhood dream I was living at 40 to own one one day and when that one came up I took her. Unfortunately Hurricane Harvey had other plans for my precious baby girl. So after Harvey I found a 2010 RX8, also a one owner, it had closer to 50k miles and a few nicks here and there, obviously not as clean as my first but I took it, it was a good price.......Anyhow..... Here I am with the 2010 Rx8 which so far I have had no problems until this month and I feel like the way the service guy explained what was going on with the engine that I might be headed down a road where this car will cost more than it is worth.

What do I do, sell it and move on or what? What do those numbers really mean, is it really near the end of its life or do I have a few more years? Any advise it appreciated

What were the compression numbers on rotor 2? What was the listed engine RPM of the test? I presume the 600's numbers are in KPa, if so, those are indeed low numbers, however a low test RPM could cause inaccurately low compression test results.

When did your factory warranty expire? Mazda North America has, on rare occasion, offered a good-faith warranty on the engine if just after it expired.

So how much is the difference between the numbers of the 2 rotors? Factory Service Manual states that the difference in compression between the 2 rotors cannot exceed 100kPa or 1kgf/cm^2.

And yeah, cranking RPM and altitude make a difference, but chances are the engine is toast. An S2 starter + good battery should give you at least 300 RPM in cranking RPM.

The cold reality is that if you sell it as-is, you will at most get $2k, probably less than that. If you put in a reman engine, I think it would probably cost you $6k, and a good S2 can sell for $8k or you can keep driving it.

Those are odd numbers to me. Mazda should have provided numbers that were in kg/cm2, psi, bar or kpa. They should have also provided a cranking rpm as well. Can you post a picture of the paperwork that they provided you? How many miles are on your car now?

I only took notes over phone and was told that 680 is the min the compression should be. I was also just told that rotor 2 was strong. I will request the report tomorrow and post. Thank you so much for replying and hopefully when I post the compression results you will be able to further assist me. As I mentioned earlier this is kind of Greek to me. I feel like I do have a good team at the Maxda dealership I go to. There used to be 5 mechanics that all had RX8s some even RX7s but I think only 3 of those mechanics are left. I know enough to know that not just anyone can work on these babies.

As far as the factory warranty goes, I am not sure. I have only had the 2010 since September last year. I can inquire but being 8 years old under 70k miles you think that would be something they may do? Man I sure miss my 2009, did I meantion when Harvey took her she only had 27k miles.....so tragic

NotAPreppie

Those numbers are kPa. Or at least kPa is the only unit where that would make sense. 660 being the minimum would correspond to about 265-270 RPM which is reasonable, depending on the condition of the starter and battery.

kbwags:
Does the car start and run normally now with the coil and spark plug replacement? If so, might as well keep driving it until it dies. There's no easy way to say how long that will be.
A replacement motor will be $3k - $5k, depending on how carefully you shop. Figure another $1k for incidentals and fluids and $1.2k+ for labor.
The part number for the motor is "N3Y4-02-200R-V0". A google search on that part number will turn up a number of dealers with varying prices.

The engine has an 8yr 100k mile warranty. The warranty starts the day the car was originally sold, so if yours didn't sell until the end of the year it should be covered. You can call Mazda with your VIN to get that info or the dealer should also be able to get it.

These numbers don't look good at all. Rotor 2 is starting to fail as well.

Speak with the dealer about the extended engine warranty. Mazda U.S.A. may be able to help as well.

furansu

I'd bark up the Mazda North America tree. They may honor your warranty if close enough to the expiration period, may offer a 'good faith' replacement, or at least a significant discount on the replacement and labor.

For what it is worth, the cost price of the reman is roughly $2650, that is how much it costs for one from Mazda Motorsports, and how much a dealership will pay for the motor. All dealers offer markup so that they can profit on parts sales, most more than others. $2800-3200 is a good price from a dealer for the engine, more than that and they are gouging, which is most of the dealers. TX, FL, and some of the North-East have very good dealerships that do not gouge owners and offer sub $3500 prices on the engine.

The fact that you are paying the dealership to do the install, you may be able to get them to cut a better price on the engine, at least insist as much, maybe speak with the service manager directly and see if they are amenable to the idea. I bought my car with a bad engine from the dealership, knowing it was bad. I spoke to the sales manager whom engaged the parts manager and I got them to drop the engine price from $3900 to $2950 since I was taking the car off their hands as-is.

Here are the best prices I've found from dealers, NotAPreppie was a big help in getting this list together:

I called Mazda USA and they said that the 2010 model did not have a warranty on the engine. Some years did due to high number of issues, unfortunately, mine is not one of those.
They car seams to run fine currently with the new spark plugs but it is disappointing that the car only has 60k miles and the engine is having issues. I am the second owner and it came with a record of regular upkeep so I find it unsettling that it is having issues so soon. I know it's 8 years old but to me 60k miles is to low to be having engine problems.

Thank you for all of the suggestions. I am waiting for the dealership to call me back to get prices on a new engine. Im hoping it won't be to costly.

NotAPreppie

You don't have to go through your specific dealership for the engine. Even if you do, look at furansu's post and see if they will price match. Most dealers think they have a captive audience and they set their prices accordingly. The links provided by furansu are genuine Mazda dealers selling genuine Mazda parts.

I am happy to hear they do sometimes offer a good faith warrenty just after expiration. Rita1963

Currently my dealer is quoting me 6k to replace the engine. Thanks for the resourse!

I have a 2010 and it came with a 8 year 100k mile warrenty.

So I got a call from Mazda USA today; it was William, the gentleman I spoke with yesterday that informed me there was no warranty. He said he looked further into after our call and was able to get me $2,800 in credit toward a rebuild. GOOD NEWS right?

So I call my dealership and talk to both service and parts managers. An hour and a half later these are the numbers I have:
3,300 for Short Engine N3Y3-02-200R-V0 (less the charge for the core) originally quoted me 4,200
150 for coolant, oil, filter, and alignment
2,718.90 for labor
TOTAL OF: 6717.05
Minus 2,800 (credit from Mazda USA)

FINAL COST 3,917

any thoughts on this pricing?

What I don't understand is I went to Russelsmithparts.com (because the dealership is Russel Smith) and the pricing was 3,000.63 (https://www.promazdaparts.com/oem-pa...e-n3y302200rv0)
and they will not honor that price because they do not order their own parts from their own website. The best they could do was 3,300. The website adds $1,000 for the core but once they get it back they will reimburse the $1,000, then shipping is only $83.00. The dealership then proceeds to tell me I can order it from their website but it will not be warrantied by them. How does this make any sense?

Any more advice out there?
I wouldn't have got this far without all the help you all.
Thanks again

With everything being counted into that the price doesn't seem to bad at all of if were wanting to move forwarded with the car. Sorry to hear about the problems so early on

I'd give Mazda USA a call back regarding your car not having an extended warranty on the engine core. This is posted on Mazda USA's website:

"RX-8 ROTARY ENGINE CORE LIMITED WARRANTY EXTENSION
Mazda Motor Corporation extended the warranty coverage on rotary engine core components on all RX-8 vehicles. The warranty coverage for the Rotary Engine Core Components is extended to eight years (96 months) from the original warranty start date, with a 100,000 mileage limitation. The following is a list of components covered by this warranty:ROTARY ENGINE CORE

• Rotary Housing and Internal Parts
• Internal Seals and Gaskets "

https://www.mazdausa.com/owners/warranty

Seems to me that 2010 RX-8's would be included given the website states "all" RX-8's. I believe there is also a time limit of 8 years from first owner's purchase date, so as long as you're in that window, I would think yours should be covered by the warranty...unless I'm missing something.

1-800-222-5500 is the contact number for Mazda North American Operations.
They might have a definitive answer for you.

That is a lie. I JUST went through this with MazdaUSA. ALL 2009- 2012 have 8 year 100k.
I just helped an owner with a 2011 get a new motor
