Yeah, definitely not pitting. Oil and dust particles on the surface.

My issue is, I wish it was coolant. Seems to be straight water.

So for how many more years do you all think that Mazda will continue to build these seemingly good remans? I ask because I figure I have about another 2-3 years left on my engine, and I am very interested in getting one of these (I'm surprised to say) GOOD(?) engines for mine. Keep in mind I daily mine and I cannot afford the time to rebuild the engine or get it rebuilt, so to me, buying a new-ish engine from Mazda with the possibility of a warranty seems like a remarkable opportunity that I do not want to miss out on.

Yah, fortunately you don't need a sense of humor to be an asset to the forum. I'm sure Mark's wealth of knowledge and willingness to help others with extreme prejudice more than make up for this.

I would assume for a few years after the SII RX-8's are out of the extended engine warranty range.

BC, it's clear that Mark doesn't see the problem with his behavior. Arguing with him isn't going to change that. Just let it go.

For a thread that started out as an informational look at the insides of a Current Mazda Reman......it has turned into a crapfest of whining and bad feelings

Get over it.....lets try and be adults and leave our "feelings" out of it.

And if you get worked up from reading comments on an internet forum...maybe you need to seek some help

Paul....If you would like I can clean up the info and put it in a new thread if you would like

paul,

as the owner of one of the first mazda remans, went in two weeks after they became available. the mileage on the motor that came out was about 50k miles. so it was about 07 is my guess.

the reman that has lasted me for 70k miles, and the last 5k were just to and from track and track.

it sits in my garage, swapped to 04greens pettit motor.. opportunity knocks you take it..

still hating i paid for an engman motor and never got to use it.. not your fault.

if you have interest it the inside of early remans, let me know. i really need an excuse to run RA.

beers

I will be buying a reman engine here this month or next. My engine finally gave way and it was as expected when I purchased the car with one rotor with low compression. Almost lasted me a season. This thread was great as I learned a lot about the part quality mazda uses in the reman engine and was a huge contributor in my decision in going this route besides rebuilding it myself.


Thanks guys. And the pricing on the remans are very good for the parts you are getting! WOOT.

I would not take this one thread to mean that anything is definitive, as plenty of recent well maintained Mazda remans have not lasted long. New parts are great but if it is assembled poorly it doesn't mean jack ****.

Which us why they make great "cores" to build a really great engine 😎

I used a Mazda reman when I built a N/A motor. The side seal clearances sucked...but I was able to re-use all but 3 of the shortest ones...and bump the next longest ones down to get good clearances and then recut new full length seals for the longest grooves.

All in all it didn't require too much waste...a few gaskets and a bit of time to recut the rotor seals that weren't what I wanted

That motor had new rotors and housings and all new bearings. The plates had no noticeable wear on them. They could have been new as well. There was the traditional sludge in the coolant cgamblers and a bit of overzealous amounts of RTV

Yes, I would definitely use one as a basis for a rebuild and that was my plan for the next one. The amount of RTV used is insane, mine was dripped all into the oil pan on my last one that lasted 27k or so.
