For those of you with replacement engines from Mazda, how long (miles) did your replacement engine last before it too failed a compression test?

I'll let you know in a couple years (hopefully). Just dropped mine off this morning. Original engine, 66k.

My first reman was installed when my factory engine failed at 22,000 miles. It lasted roughly 74,000 miles. Completely stock, No premix, regular oil changes using Castrol 10W30 and that engine saw 90% highway miles due to my long commute during that time period. I got a second reman at 96,000 and that engine has almost 30,000 miles on it but has had no cat, premix, SOHN, and BHR iginition since day one.

Can't say, as I've had my 8 for over 5 years now and it's still running great with the engine it came with. Sorry.

No one knows when they gonna die.

Same thing for Engine life.

just because Engine A last forever, doesn't mean Engine B would last the same, it probably die the moment it's install.

According to Mazda mine was replaced @ 19k (original) and 47k, bought with 89k. I now have 95k on the odo.

How many miles in five years? Oh and someone can't add.

Never had mine replaced, but i think it depends on how you take care of it. If you take care of it, then it might last longer, if not, it might not last long enough...so, it really depends, not how long will it last.

I had one last about 360 miles. Another never even started. And the last one was still running after 65,000. So how can you tell how long one will last?

Wow, that was such a profound post. Thanks for the enlightenment.

Apparently I just found out mine had a engine replaced in it (Or so the previous owner believed but was not 100% sure). The car now has 97K (KM.... 56k miles) on it, and problems are arising - Possibly again?

Anyways, I guess this MAY be the second engine in the car. And Mazda said it will take a long time to find out if it is because the car was imported from the States.

Hmm....

sorry but this poll question is worthless.
Too many variables go into how long a Reman will last (where was it made, when was it made, etc) and not to mention location of vehicle, maintenance, driver behaviors, modifications, etc.

I'm just curious though how long they are lasting. Sadly though many just get rid of their RX-8's or don't keep them long after having an engine fail.

between 1 and 300,000 miles.

I wish Mazda would just come clean and tell us what the majority of the failures are caused by.

That's hardly a secret. If it's not an '04 with first-year teething problems, it's owner neglect. Do you have any idea how many owners fail to check their oil regularly, fail to rev it high regularly, fail to let it warm up before pulling out, fail to use the proper grade of motor oil and fail to put anything except gasoline into their tank? That's gotta be a sh*tload of owners. Hopefully the S2 revisions will afford negligent owners a little extra margin of owner error.

monchie

Anytime homie.



Yes you didn't, lol

You realize that with nearly every other car, you don't have to do ANY of those things (except the oil grade; that part is pretty important). And it's not like Mazda tells you "Be sure to do the following or your engine will explode!"

New Yorker

Well you're right, of course. The maintenance for a rotary engine car will be a little different than for a piston engine car (and I imagine the maintenance for an electric car is a little bit different, too). Mazda probably wrestled with the problem of how to communicate what needs to be done without scaring off prospective customers, already wary of a "different kind of engine" to begin with. Tough tightrope to walk.

So you are saying any failures other than a 2004 model are due to owner neglect, not redlining it, driving their cars cold, premixing, and running oil other than 5W-20 (even though that's a US Spec and everywhere else Mazda recommends otherwise)? I hope you own yours long enough to experience a failure so you can STFU. You won't be the first to brag about having a problem free original engine and then have it fail

There is no one reason for the failures and no one really knows what the main mode of failure is because not even the dealers are allowed to take apart the motors. Could be the lack of a third oil injector, could be the low oil pressure, could be carbon build up, owner neglect by not adding oil as needed, etc. But the fact is that the only data we have is from the few rebuilders that have given us input/opinions.

One can speculate (I do) what the faults are on the S1 engine based on the changes made to the S2 Renesis but that is it. I admit owner neglect by some is a part of it but I also know quite a few guys/gals aside from myself who took perfect care of their motors and they still failed prematurely. My second motor lasted a good amount (74,000) despite OCD like maintenance but i still think that is low for a modern engine. I think 50-75k is about all you can expect without seeing a loss of compression and even then many drive around with low compression motors without even knowing it.

You always talk about you having an 05' with no problems but you never answer the question of how many miles are on your car. I assume that means you have below average mileage?
