i have a 13b non turbo that wont hold compression and everyone says its becuase of bad seals and if you add ATF, it will inflate the seals temporaily and be drivable.

i plan on repairing the seals myself.

could yall be so kind to point me in the right direction?

any specfic tools i need?

where can i find the seals?

how do i install the seals?

and will a 13b turbo II engine, fit in my 1987 RX-7 non turbo, 4 speed auto?

i plan on making it a 5 speed manual as well.

any advice or help will be greatly appreacieated.

 

If you don't have compression then you probably have a blown seal and no ATF won't help.

You can't repair seals, you replace them which means you have to take the engine apart (a.k.a: a rebuild).

Search for the engine and transmission swaps, they have been covered enough already.

 

If you have no compression at all on any faces then the engine may have been flooded and then carbon locked. If this is the case then the "ATF trick" might work, but I would use a bit of regular oil rather than ATF. ATF can dammage other seals while it is in the engine, regular oil can do the same job and cause less dammage.

If you have low compression on all faces or you have no compression on 2 faces and some compression on the other face then the engine needs a rebuild.

 

No.

Download the factory FSM and read the ENGINE SECTION of that manual.

Then visit Mazdatrix online and take a gander at parts prices. Or look at other places that sell rebuild parts/kits.

Then see if you want to press on with this idea. By the way, the apex seals are steel and have a hard time inflating. It's hard to access their valve stem with the air hose. small humor.

 

I have a set of factory 2 piece 2mm apex seal fs. $270 shipped.

i have a new set of Rotary aviation seals for sale 140

maybe yall can help me here.

i found on ebay, some seals that were really long and a few shorter than the long ones.

???

i thought they were REALLY small and just fit in the springs.

could someone please post up a pic of how the seal system works. including pics of ALL seals.

its a 87 motor so i guess ill just replace all the seals since its going to be apart anyways.

 

get a hold of Dan Atkins(on forum)or try www.atkinsrotary.com .they will Tell you Exactly what you need to hear or Need to get.and If you Have no idea HOW a Rotary Engine Works,No BULL,the best thing to Do is to GOOGLE:rotary engine,or Wankel engine.The Links will lead you to a Site that has Pictures of a "cutaway" rotary engine..and you can get the Idea of how the engine is Put together and what and where the seals Are,and how they Function.

 

i know how a wankel works, its just the seals thing.

is that a common problem with mazdas?

and how long will the seals last after i put them in?

 

this thread is so retarted...ya just buy some seals and yur all good to go....come on now, you dont know what the internals look like yet not to mention needing the gaskets and many other things to do the job including tools garage engine puller time experience money ? etc etc... none of which after reading your opening line

"i have a 13b non turbo that wont hold compression and everyone says its becuase of bad seals and if you add ATF, it will inflate the seals temporaily and be drivable."

appears you have very little knowledge to begin with...

do some research, check out rotary resurrections site and ...good luck

if you rebuild the engine, it will last as long as your imagination can take you.

on a serious note, since it seems ur determined, i will caution you to take ur time and research for many many hours and realize the cost of tools like engine hoist and shop press if u plan on replacing bearings also and how much of a bitch the flywheel bolt will be.

may the force be with you.

 

this post leads to everyone to draw conclusions that you have a long road or learning and reading ahead of you.seeing an animation on how a motor works or reading up on it is a little bit different when applying it.if you did throw a seal,you might want to find housings as well.specially w/ a motor that has a fair bit of miles on it.high mileage housings are never a good idea to reuse.better off finding ones that have low mileage.if you did throw a seal,you might need a rotor as well.

 

Go to the Factory Service Manual and read the ENGINE section. The engine section disassembles the engine and then reassembles it. You can see graphics of the seals in that section.

The FSM is free for a download and the location of the download is in the FAQ thread at the beginning of this second generation site.

 

Someone needs to read. The atf/oil trick is like last resort to free up the seals so the motor has compression again but does not work every time. And if you are doing a full on engine swap???nonturbo to turbo rebuild your engine or your gonna have wasted time and money I speak from personal experience. And when you have freash rebuild you can modify your car with no problems. My 2 cents
Atkinsrotary for rebuild kit or check out rotary resurrection to build it for you. hope you have a fat wallet.

 

If you take a look at the FAQ, there are several threads with links to detailed descriptions of engine rebuilds. Reading through those threads should give you a better idea of what you are up against.

As others have mentioned, replacing the "seals" requires an engine rebuild which may or may not necessitate the replacement of other parts as well (such as housings). Read through the rebuild threads (especially the tutorial by RotaryResurrection) to see the process.

 

hey i live in ga send me an email well talk

Let's see now. I'll try again. Download the Factory Service Manual from the site given in the FAQ thread at the start of this second generation site. Download the ENGINE section and look at the pictures.

 

damn guys. thanks so much.
