I did a search, of course , to see if this was ever started and it doesnt seem like it has.

I want to start a poll to see who has blown an engine from what rebuilder, and each rebuilder will have a "My fault" or "Their fault" selection.

Kinda like:
Pettit - Blown due to me boosting at 30psi with stock fuel pump
Pettit - They focked up the rebuild.

So, who are the big/common rebuilders?

Atkins
Gotham
Hayes
KD
Mazda Reman
Mazdatrix
Pettit
PFS
Pineapples
RP
SR Motorsports
Tri-Point


Anyone else you guys want to add to the list?

How do you ever know it's the rebuilder's fault? There are lots of grey areas...

Flybye

When the rebuilder is honest enough to say "We messed up and will rebuild it for free" or when you tear apart the rebuild and realize it was incorrectly put together or put together with used parts or if you took your blown rebuild to another shop, they tear it down, and they tell you "The previous shop screwed up"

I heard Mazda remans were a little LESS than expected..

Hmmm, I've yet to hear a rebuild say that... Look at the current "Pineapple" saga.....

Flybye

Reason I want to include Rebuilder error is because I've known of at least 2 people who have opened up their engine and found other obvious spots of error.

Like one guy I knew up in PA that tore apart his engine when it blew prematurly. The end plates were scratched up more than what they should have been, and it seemed as if the rebuilder used someone else's end plates. He verified his findings by taking it to another shop.

That's the same as what's going on with the Pineapple saga right now, however, Pineapple is saying that none of the problems listed were the reason for the engine failure.

I think that's what Damon is saying which is; even with problems listed, how do you know that these problems caused the premature failure of the engine and prove that?

And the rest... So, all the shop has to say is "that's not the engine we built"... Unless they stamp their names all over every part, it's basically a losing battle when it comes to "proof".

Like I said, I've yet to see a rebuilder claim responsibility for a premature failure and then fix the situation out of their pocket.

I can't speak for all the reman motors but the one I got had new rotors and housings and is running wonderfully strong while getting raced constantly; almost 25,000 miles on it now.

Put Malloy's Remans separate from generic dealer remans.

Mahjik

I think the engines are old enough now that they are coming back with mostly all new parts. Back in the day, they probably reused a lot of things they shouldn't...

Over the last 2 years, just about every reman I've heard about being torn down to port has had new rotors and housings.

I have no idea what my reman has new inside, but it's been going strong for about 5 years (about 27,000 miles).

Mahjik

That makes no sense. They all come from the same place. Malloy doesn't rebuild them themselves.

Awesome news. I can't speak for them either.. I just remember a thread a while back where there were several people complaining about remans.. They would send them to KD or similar to find that there were clearance issues among other things.. Not trying to steer anyone clear of a Mazda reman, just commenting.

If that's the case then I'll retract the suggestion - I thought Malloy did them differently.

Wouldn't SR Motorsports be considered a big one too? http://www.srx7.com/

What you should do is create a poll that has every engine builder on there and let people vote on who they have used. Then take that info and create one on failures. There are alot of engine builders out there that arent on the forum and some that are that have built very few engines for people. That will give you an idea of who has been doing engine rebuilds for a while.

How about Tri-Point?

Mazdatrix - my fault

In fact, the Mazdatrix engine survived several overheats, lots of high boost madness on pump gas, and one huge overboost when my wastegate got stuck. I eventually leaned the fuel maps out too much and broke some apex seals on one rotor (the other rotor+housing still looks good and will be reused). The engine had 25K miles on it. The car is at Mazdatrix getting another rebuild now. I like Mazdatrix. They aren't cheap, but they seem to very meticulous in the engine build, do good porting, and they won't BS you.

Like all of these reports will be, this is just my opinion.

Apex seal failure is always an iffy subject, but on the side plate issue... his side plates were significantly damaged to the point that they prematurely wore out and damaged the corner seal then it continued to scrape the hell out of one of the corner side plates. The plate wasn't even perfectly flat. The apex seals were not even damaged.

I'm no engine builder, but there are usually ways of telling what failure was caused by what.

Whether you were able to have the shop admit they goofed or not, or if you had another shop vouch the failure was caused by a poor rebuild, or even if you are a good enough engine guy to know that the failure was caused by where you previously bought the engine, then that's good enough to know that it was the builder's fault. Granted, you wont always know if it WAS their fault or not, but at least the people that DO know for a fact will be able to vote on it.

Even if most failures are due to poor tuning & overheating, it will be kinda of fun to see which engines fail the most. Considering the proper ratios, of course

And we can just ask everyone to make sure they type the name of their rebuilder in their reply with their comments. This way, anyone can do a search in that thread for the rebuilder they are considering and view everyone else's experiences.

Ok I updated the the list Anyone else to add?

Will Mazda ever stop making Remanufactured engines?

Mahjik

iTrader: (1)

Sure, as soon as we quite blowing them and there isn't any profit there anymore.

Technically, they aren't "making" them, but "rebuilding" them.

When you pull apart a freshly assembled engine from Hayes Rotary and every last thing inside is fucked up in one way or another.

Flybye

One more to the list.
Any other big boys?
