Poll on RX-8 engine replacment

[RX-8888]

I can tell you now your Mazda Dealer will not recommend pre-mixing..

I have had over 35 years experience with Mazda as both a Parts Manager and Service Adviser..

Here is a large link on the subject from the US site, keep in mind our engines (internals) are identical worldwide.

Why pre-Mix, as stated the original Oil Metering Pump is not delivering any oil to the middle of the Apex Seal, why do you think Mazda have added a Middle oil Injector in the 2009 Series II RX-8\'s? (R3), and TWO Electric Oil Pumps, not the one Mechanical on the Series I.. because it was not getting sufficient oil to the middle of the Apex seal...But hey...don\'t believe me...trust your Mazda dealer..

The existing MOP in Series one has 2 Injectors for each Rotor Housing, they weep oil ONLY to the edges of the apex seal, not to the centre.

By pre-mixing into your fuel you are adding additional lubrication for ALL of the combustion areas of the rotor and it\'s housing.

You will find on the US site, particularly from "teknics" a rotary Owner and Mechanic who works at a US Mazda Dealer...he also 100% positively recommends Pre-mixing, to use his words there are only "Positive Results" when you do so and NO "Downside" to doing it.

If you care to look at most RX-7 Club Forums many of the owners also Pre-mix.

Those who Race rotaries also add much larger amounts of oil to their fuel...I wonder why?

Engine failures (poor compressions) are occurring in RX-8\'s around the $50K mark on average.

Here is a Pic of the New Oil injector set up (from Mazda Japan\'s Media Site) for each rotor housing on the series II RX-8 (R3) with EMOP.

Notice the middle (third) injector, Series I 2003-2008 all have TWO Injector Nozzles exactly in the same position shown in this 2009 Pic, both weep oil to the outer edges of the Apex Seal not the middle.

But hey...don\'t believe me...trust your Mazda dealer..

It\'s not that I don\'t believe you - I just know that if I do have any problems and I\'ve done anything Mazda don\'t recormend then the chances of them helping me out are zero.

Mazda have always been really great and helped me out with a few things - including actually getting me my car in the first place as my original one was destroyed in the factory fire back in December 2003.

I just don\'t want to risk it as it\'s still under warrenty.

[RX-8888]

Believe me a dealer is not going to know if you pre-mix..
Again I suggest to you Ann, look around the US site a little...in the Tech section.

And you don\'t think Mazda and most dealers read these forums? Mine certainly does - not that I\'m saying anything just to keep them on side.

My local service dealer also stated that he visits MRC at least once a week.
Makes you wonder if they are just keeping check, looking for problems or just extending there knowledge.

Is this commom, my car has full service history from new. I have owned it for 2 years. it is a 2004 registered model.
Any advice on what i should do, the cost of repair is in excess of vehicle worth.

Sorry to hear this, is it common? (I could put up an average percentage but some don\'t like hearing it).

Have you had your car serviced at any Mazda Dealer?, if so you could approach the dealer to represent you in discussions with Mazda UK.

Or approach a dealer anyway, they may be able to suggest a suitable outcome, either way it is going to cost you, you may have to pay a percentage, say 50%, the rest Mazda may pay as "Good Will".

Unfortunately Australia (where I live) and the rest of the world does not have the 8 year warranty like North America/Canada has.

Failing that you have to find a Rotary Expert Garage who can do rebuilds.

I am sure someone here can assist you...good luck.

dont worry dude. My 8 is an 04 with 63k full service history and drives like new. Im not worried about all the above as i have just spent 3k on bodywork mods lol

[RX-8888]

^^^^

Don\'t worry Dude???


My RX8 has had an engine failure at 60k
Read the post agian..
This person has a blown engine at 60K and wants advice and help.

[AshRX]

Looks like a first post to me for whom I was talking to!!!!!

oh sorry i forgot that soon as a 8 hits 60k on the engine its game over for it and its all downhill.

RUBBISH!!!!!!!!!!!!

^^^^What Ash said!!

I have a 53 plate with 53k on it and had it re-mapped at Re:worx a couple of weeks ago. It ran 220bhp stock! (apart from induction kit and sorry don\'t have the print out) Believe it or not, I think that is not really so much down hill over 50k miles. After the re-map and a new exhaust and hi-flow cat I creamed an R3 just this weekend and even a 55 scooby turbo couldn\'t get past off the lights on a 2 lane national limit (although to be fair I couldn\'t get past him either).  

I\'m not worried at the moment either. I\'m just going to drive the car and look after it as recommended and best I can. If it goes it goes! apparently its too late anyway.
 
I will be getting a magnet though because they seem pretty cheap, it sounds like a perfectly good reason for doing it and can\'t do any harm.

Shame RX-888 lives in Australia or we could see whos engine is better:flamed

[gsb876]

what is the actual cost of rebuild for a RX8 engine ??

[nicktyler]

I suppose it depends where you take it Re:worx engine build page says upwards of £3000 for a FD3S TT. I imagine a renesis would be around that price but it would probably depend on the extent of the damage and the parts needed and therefore the labour hours to put it right.

[Brett]

Surely with a renisis you\'d just buy a new short block from MAzda (if it came to it) and get the warranty etc?
