I have to ask if the seal and housings are fit correctly how would a 2 piece seal work better.
after searching I have been unsuccessful at finding anyhting about this.

more curious than anyhting....not really in the mood to argure with years of mazda engineering anymore on this build....:)

Chino_rx3 07-16-2012 07:24 PM

oem is more expensive but is way better, I just ordered my side seals for my rotors wow,, 350 and some change wow. But I feel better once is in , I would comment on your last post but im a noob I dont like getting chewed out .. lol maybe in a year or so when my car has hit about 30k on my rebuilt I can talk lol

houstonrx8er 07-16-2012 08:10 PM

are you sure you got the right stuff man? MAzdatrix shows them $15 for cut to fit or $25 for "letter" stamps?

Mazda did explain why they choose 2 piece over solid. basically when it's low speed/idle, the rubber piece will help stabilized the Apex seal, or something like that.

Let me try to find it ...

if u want better sealing, buy cut to fit (extra long one)

u just need a dremel tool to make the perfect cut. just do it slowly, REAL slow. until it fits.

olddragger 07-16-2012 08:34 PM

real slow, did we say REAL SLOW....
yep --real slow.
meant to say very slowly, a little bit at the time, very little, just a smitten--you know REAL SLOW
ok yea and one at the time too:0
Sorry I have had a couple gin and tonics--27th wedding annversery and all

houstonrx8er 07-16-2012 08:36 PM

^ yep...slowly....its pretty tedious but not overwhelming at all

also, I have been heating my irons in my oven. I set the oven to 450......just kidding 200 and its taking a long ass time to heat them up.....bet it takes all night to cool down

Congrats man:nopity:

I'm ok with stock I been debating on witch to get and OEM is the say to go for me . And this build is of mine is slow enough I can't go any slower lol

O I know I got right ones I went with my mechanic and at cost their were 28. And some at 25 and change .. mazdatrix I would of paid shipping I believe .

research....I am not sure you want to tackle this if you cant decern between rebuild kits:dunno:

so you bought the "lettered" side seals.....should have hand cut them :naughty:

I got the soft seal kit with Atkins and Mazda parts like Apex seals , Side Seals , Bearing with Mazda .. is more expensive this way but I'm sure ill be happy with Results . Atkkns full kit is way cheaper but you have to make that call

houstonrx8er 07-17-2012 08:44 AM

yea we got the same basic kit...I just went cryo and hand cut side seals

looking forward to you getting it on the road :)

Lol na I'm good Bro I've search weeks and read many many things about it and in my own little world and my mechanics world OEM would be fine... Just like Mazda cuts Apex seals and bearing and they work great Side seals would work great too ..

Sorry man...not you...the other guy asking about OEM vs. Atkins...I know your good:aroused:

Ask yourself this; what was Mazda trying to deal with when they developed the two-piece apex seal. And, along those same lines, why did Mazda also develop the "keystone" side seal design?

The tip-off for me several years ago was what Pontiac had to deal with when they offered the 455 Super Duty engine and discovered piston slap to have been a major concern in the Midwest U.S. during the winter months..........

I think I understand the curcial dimensions and why....part of the reason I am curious to measure my housing with my starrett micrometers that will be here tomorrow :)....I think 1 thing mazda was accounting for was a factory produce engine...not coddled hand built (regardless of the fact mine is a POS that I screwed up :))....also expanding metal is another issue...when cold loose seal but seals when hot

not sure I have an answer on the side seal shape though :dunno:

houstonrx8er 07-17-2012 09:17 AM

duh on the temp...I think thats what you just told me with your 455 comment.

9krpmrx8 07-17-2012 09:26 AM

Are you trying to scare me with that gun?

houstonrx8er 07-17-2012 09:35 AM

So about bore alignment.....if I have new irons and the e-shaft is "as straight as an arrow", the wear has to be as a result of the stationary gears not being "square" (not a result of the bearings as they were new). Is there a way for me to measure between the bores???? I am alsmot willing to accept bearing wear at this point.....:lol2:

9krpmrx8 07-17-2012 09:38 AM

On a piston engine first the block is align-bored and then the center-line of the crankshaft is established right? I am going way back into the brain for this stuff :lol:

So you may need some boring done? I think I comprehend.

houstonrx8er 07-17-2012 09:52 AM

I think the alignment of the 2 stationary gears is what he is refering to....I will re inspect my gears to make sure there isnt anything keeping it from seating (pretty sure just gonna check again)

9krpmrx8 07-17-2012 01:16 PM

Awesome, I have much to learn on Renesis rebuilding.

Since the e-shaft has been determined to be straight he now needs to measure the journals on at least three axes (six, preferably) to establish them as not being out of round. And write these dimensions down.


I had measured the journals with my calipers when we did the first teardown and everything was +-.001 (I think....posssilby +-.002)....I can measure them with my calipers again but I think I will just wait for my micrometer to do it right.

olddragger 07-17-2012 04:03 PM

actually on geting a recip bore true --they now include torquing the heads on the block and then trueing the bore in relation to that finding. The torque of the cylinder heads can cause the block to change the bore from a true round. That results in leakages.....
I do wonder if things change a little within our engine when everything is torqued down--including the front and rear stuff?
What is the proper way/sequence in torquing engine bolts, etc. Just use the star pattern approach? Slow torquing method?

By the way --we did celebrate--hell of a woman to stay with me this long--lol

There's a very odd but methodical tq pattern detailed int he rebuild manual.

I dont have the book infront of me, but I;m sure one of these techie guys can take a screen shot for you.
