an RX8er's rebuild thread

is that a true flat edge? If it is then damn--you need to tall with the person that sold them to you.
when did you start wearing fingernail polish?![Smilie](https://www.rx8club.com/images/smilies/smile.gif)
Where the hell did that mark come from?
easy to see the contact mark midway on the apex--you can see how a taller seal may help some people.
09 housings can be used in earlier models? I thought they are slightly different?

I assume that wear horizantally across the apex from the rotor slot is normal?

Guess I will just send an email with some photos and see what happens

no damn wonder you didnt have any compression--if all your apex seals look like that.
I have no idea what made that mark unless one of your springs got caught somehow?
Expensive lessons--and I agree-- send them pics of those seals--thats ridiculous.
you may have seen this site before but for those that havent, look at this

I took my reman out and it was fubar'd so I bought new irons and slightly used housings which was great, reused rotor and e-shaft....decided to go atkins cryo and not measure everything before installation...big no-no
and no on the taller seals...that is what Atkins sent me.....and I am very confident the springs were installed correctly.

Brett,
Yes they were.
Houstonrx8er,
That is why I didn't go with Atkins for my rebuild. When I called to ask questions the guys was obviously annoyed with all my questions so I just called the next builder.

i know someone that used s2 housings and hooked up the third nozzle to work on a s1 rebuild

And yep their customer service stinks. I remember asking questions then I said forget it Hung up called 2 days later and said can I order kit B with frys that's all thanks . Lmao.. their order takers Bro not Racing Beat lmao... Seriously

Just interested in this - seems they use a slightly taller than OEM seal (by 0.5mm) but this is not the rx7 seal . The effect of this would be that it would be a bit stronger but also the spring would be compressed more . So is this a good thing or a bad thing ?

ditto....and it sure as hell isnt flat

they all have what I would call a scalap but the photo is pretty much the worst one. also it is not the same apex in the photo below
I will get all of the seals finished up (I still have 1/2 of a rotor/seals to clean) and get pics of each one with all the measurements and hopefully that will help vs. me trying to explain them poorly![Smilie](https://www.rx8club.com/images/smilies/smile.gif)

A recall one very experienced engine builder claiming, that Atkins apex seals have higher thermal expansion rate than OEM stuff and they need to be instaled with bigger clearance, otherwise they will stuck in groove.
Does the sliding surface of apex retains its radius? Or its worn-out?
There are too many things going on, I do believe that it may started as clearance problem, but as the apex seals didn't properly seated, blow-by increased their temperature to the level where apex warped or worn-out in the middle

Thats very unfortunate. This way it will be very hard to judge where wear occured, if the apex seal to slot clearance was correct etc.
A recall one very experienced engine builder claiming, that Atkins apex seals have higher thermal expansion rate than OEM stuff and they need to be instaled with bigger clearance, otherwise they will stuck in groove.
Being 0.5mm taller does only one thing, it pushes spring further, but it doesn't increase its tension. But this didn't caused poor compression.
What do you mean by this?

interesting about the expansion rate of cryo parts...never thought of that, just how it transfered heat
regarding the scalap, I was refering to the lip at the end of the seal...its called a scalap.

I cannot wait to get this stinking work project rolled out....it is totally distracting me from focusing on this rebuild

ok, housings, apex, corners, bearings, eshaft have all been ordered ![Smilie](https://www.rx8club.com/images/smilies/smile.gif)
gonna look at..... finishing my coilover sleeve perches, possible oil cooler flush, and geting the bung redone on my pan
hopefuly it will work this time![Lol2](https://www.rx8club.com/images/smilies/lol2.gif)
measurements to come shortly
