I DID THE ATF THING ON MY 88RX, AND IT FIRED UP JUST FINE. HOWEVER

WHEN I WAS PUTTING THE ATF INTO THE PLUG HOLES, I NOTICED A SMALL

AMOUNT OF WHAT APPEARED TO BE COOLANT COME OUT OF THE SPARK

PLUG HOLE WHEN I BUMPED THE ENGINE TO ADD MORE ATF TO THE SAME

ROTOR HOUSING. I AM TOLD BY A REPAIR SHOP THAT SPECIALIZES IN MAZDA REPAIR, THAT I MAY HAVE AN INTERNAL SEAL LEAKING, AND THAT THE ONLY THING I CAN DO IS BUY AND INSTALL A NEW ENGINE. HELP!!!!



I KNOW OF ADDITIVES I HAVE USED ON OTHER ENGINES TO STOP LEAKY

FREEZE PLUGS AND OTHER THINGS. WHAT I NEED TO KNOW IS IF ANYONE

HAS SUCESSFULLY USED ANY PRODUCT SUCH AS THIS ON A ROTARY

ENGINE, AND IF SO, WHAT DID YOU USE?

those addidtives are only cruches, ur gonna need a rebuild. If u do it urself it could run u cheap, and if its only the seals then its not too bad anyhow as far as having someone else do it, for $$

i've had (still having) similar probs from rear rotor. took apart engine and replaced some gaskets and water-o rings but not a complete rebuild. helped for awhile then discovered other source of water leak... from intake manifold/water port down to an intake port across the gasket. after fixing that the internal water leak returned a few months later.

the car still runs but is a real pain to get started sometimes (the colder the worse)



good luck! https://www.nopistons.com/forums/pub...DIR#>/excl.png

Still trying to work around this hard starter until I can afford a bebuild or

replacement completely. In order for the coolant to leak into the rotor

housing it must have adequate pressure to do so, therefore when the

engine is running, if any coolant is seeping into the combustion chamber

it is safe to assume that it is burned off, because the plugs are still firing.



However, when the engine is shut down after running the pressure in the

cooling system increases since the coolant is no longer circulating. I am aware of the coolant recovery system, and what it is supposed to do.

My theory is that if the pressure can be removed from the coolant system

after the engine is shut down, this would possibly prevent any coolant from seeping into the rotor housing after shut down, thereby eliminating

any fouling of the plugs, and making it easier to restart after the engine has sat for awhile, say overnight.



This seems logical because I have driven the RX7 after getting it started,

stopping the engine to run into the store, or buy fuel and it starts right

up everytime.



So, does anyone know of a way to vent the coolant pressure without

losing the coolant. Any thoughts?
