Got my rebuild kit in the mail.





i bought the rebuild dvd from atkins and rotary aviation. it looks like i should be ok rebuilding it myself, if not i have a few friends that have rebuilt a 13b before.



in the dvd bruce said you can tell if a rotor housing has been severely overheated if it is brown on the bottom, i guess i can see how that one looks when i get the apart?

i found a corner seal spring in the oil pan... wonder how that got there, hopefully just fell in last time it was being rebuilt?

Rebuilding my motor (my 1st time) wasn't the hard part.....it is remembering where everything else goes.

Good luck man. Did you get the video that shows putting everything back together and not just rebuilding the block?

I labelled EVERYTHING when i removed my engine and tore down my long block. I used a sequenced system of letters and numbers to match the peices.


.......Absolutely pointless


With a color coded vacuum diagram and the FSM it is very easy to find the homes for every part. All of the electrical connectors are unique (for the most part) so as long as you know where the harness goes you can find matching pairs easily.



I would wish you good luck on your project but you shouldnt need something as placebo as 'luck'. Only takes hardwork.

I cleaned of most of the parts.



heres a better picture in the dent, i dont think it is too bad because it isnt on a sealing edge or anything, what do you guys think?



Can you get new bearing for the stationary gear? i think i need one

Were the videos worth it? Im still debating rebuilding myself or paying someone to do it. Im deployed at the moment so I have a while to make up my mind.

I think I remember seeing another thread about that little dent in the rotor face. Some guy took a pic of it while it was still in the housing, through the exhaust port. From what I remember, all the rebuilders were saying it was normal.

I really hope you got a new stationary gear bearing. That one looked trashed. Copper showing through = fail.

yeah do your bearings for sure but get your rotors etc balanced first as the bearings look seriously worn!! one other thing, what is the price difference/quality of that aftermarket gasket kit compared to the OEM Mazda kit and what exactly comes with it?? Has anyone else used/ recommended it??

From what I've read, ehxaust manifold cracks are pretty much to be expected on higher mileage cars. That's why I've got a set of turbos with about 30k on them for when/if my motor ever goes. And I assume I'd have to replace the manifold too.

White94RX: i will not worry about the cracks too much, i emailed Turbodynamics. apparently they do alot of turbo modding and repairing. depending on what theyt can do to the turbo's and for how much i might send them to them, they can also fix the cracks.

chugging like a champ

As i posted in another thread i was worried about the engine because it was not turning easily, i bolted on teh thrust bearings washers spacer etc, and now i see its just fine.

Here, watch this video and Rob spins the motor with a wrench on the front bolt....should give you a general idea of how easy it should turn......in the vid its at the 2:30min mark

Actually, just watch the entire video, it's shows how to check the end play.

BTW, Rob's video is much clearer on how to set the end play than Rotary Aviation's video.

if not, what could i have done wront putting the engine together.
here is the video with the spark pluggs out, ill make another video with them in, you can here it whistling out of the plugs, with them in its more of a chugging out of the exhaust and sucking in the intake ports.
