this is the second time i've seen people selling used apex seals, who are the tards selling them and more importantly who the hell is buying used apex seals? some jerk weed out there building engines with used seals? come on out, we won't beat on you....much.

(no it's not my auction Zach )

this is like buying used brake pads at pick n pull, you may or may not stop using these parts same with apex seals, your car may start and run or it may not.

I have a set of used apex seals with 89k miles on them. Find out who the buyer is..........I could use beer money. I had no idea they were worth anything........

they are to some people apparently...

i have about 20 used sets of seals if someone wants to buy them, i have been using them to clean rotor grooves.

this is like selling used toothbrushes

1st gen owners are on completely different budgets from 3rd genners, typically.

I'm selling my set of used OEM apex seals that only have ~4-5k on them, mazda reman had a soft seal failure so I went with Atkins 2pc. seals. Had alot of people ask for them lately.

jhammons01

I stand corrected, they do have a purpose!! They are THE perfect size tool to scrape that carbon out of the grooves........

Maybe the buyers are scraping rotor grooves and they need tools.

that's so nasty. hahaha.

Bob_The_Normal

Haha... geez. The closest I've come to selling used seals was the seals in my engine that had a catastrophic failure due to... certain... things.

Half the seals are still in perfect condition.. the engine probably only had close to a day run time on it, mostly at idle, and showed very little wear (I was surprised how un-used they look actually)

I haven't sold them, no one wants just 3 seals. The other 3 seals were destroyed though... *shrug*

I'd never touch those from the ebay auction though... jesus... the reasons I could say to stay away from them could go on and on haha... "unknown mileage" ... wow...

im using some used ones just to **** around with but nothing serious....if i were to get serious about rebuilding an engine id use new stuff, but since im just ******* around im not going to buy a rotor rebuild kit for 1000$ just to mess around with....thats just stupid....


:AA:

$100 says i can make a motor run as good as any other with those.

any takers?

jhammons01

Sure you can make one run "Just as good" but did you say "just as long"? That is the issue. Just for kicks I mic'd mine per the FSM specs and they were within tolerance but the question is "why"? Why would you chance putting seals that had 89k on them back in the motor?? What are Apex seals? $250 for a set? I really don't remember right now but its something like that. After pulling a motor and all the work to rebuild, Why???

See, that's the problem with Mazda remans, the use every piece that is within factory specs. who cares if it makes no sense?

GUITARJUNKIE28

because when you're getting 450+whp on 91 octane, you're gonna break something before it wears out

why do it?

because i can.

i'd put $100 on it, there is no way they will build as good of compression as new seals. as well they are more brittle, they may work for n/a purposes for a period of time but there is no point saving a couple bucks vs the headaches of doing a rebuild twice and likely costing more due to worn rotor housings.

seals tend to build up a worn edge on the sides which mate to the rotor housing, putting used seals in an engine will just cause excessive wear until they finally seat in ultimately causing lower than average compression than it should've built with new seals.

you probably could build a motor that doesn't plan to see the road much just to dick around with but i would never rely on anything used for a daily driver.

GUITARJUNKIE28

no faith?

rotorchick

There's actually 6 bids on them

GUITARJUNKIE28

**** it

jhammons01

Even looking at it from that aspect, your losing HP due to the Apex surface not mating with the Rotor Housing. This is the very reason Mazdatrix won't use Rotor Housing again and a basic rebuild is $2k with them. Every surface that does not have maximum contact is an area for compression to slip by, therefor you loose that compression and also HP. This is the very reason why so many rebuilds only go 20K-40K and give the Mazda Rotory a bad name in so many shade tree mechanics eyes

Also with the lost compression that 450+ HP is actually moving farther away from your grasp.

Guitar, with this one I'm loosing faith in you....

GUITARJUNKIE28

1) it'll mate to a good housing just fine (assuming the seal is actually good)
2) we'd all love to use brand new housings every single time... chalk up new rotors, irons,etc... but not everybody has an extra $5k just laying around.
3) even IF some compression got by, the hp difference would be negligable. there simply isn't enough time for the compression to escape at 6-7k rpm.
4) seals not sealing has nothing to do with people breaking apex seals. that's caused by poor tuning.

have you ever seen an apex seal actually WEAR out? i've seen some that looked pretty shitty after 200k miles, but the engines still fired right up and ran fine (except the shot coolant seals and broken land)



and all that being said, the only time i actually reuse apex seals is either in my own engine, or if i'm doing a favor for a broke-*** friend my point is used seals can work fine as long as you know what you're doing. i don't care who has faith in me. if i ever build an engine for you i'll use all new everything, and it'll cost you $7k.

BoostedRex

I still wouldn't use them in one of my engines. With as cheap as new apex seals are I just couldn't justify that risk. It's not like we're talking side seals here. Just my .02 though.

GUITARJUNKIE28

what risk? nothing magical happens to a seal when it's removed from an engine. if the engine had perfect compression before, the only reason it wouldn't have perfect compression after is if you screw something up.

My engine detonated and I think my apex seals are still OK. But the block split. How did that happen?
