i literally fell out of the chair laughing..the guys at work are all looking at me like i am crazy!!
i know what sea foam is.. it works really well on the sr20det, ca18det and the sw20det. but i am not sure about the rotory.. i used it on a 12a in a fb i had that had something like 120,xxx miles on it and about 500 miles later the engine was toast... i am not sure if it is because of high milage or the sea foam.

It seems to me that with this car there are some areas you do not want to loosen up due to unintended consequences. And this may apply to coolant flushes and fuel cleaners also. I would not use it. Change the oil several times like others have mentioned. This is actually a good idea everytime you change the oil. This based on doing oil analysis.

The only time I ever use seafoam is through the vaccum line to help with carbon build-up. I wouldn't put it in my oil.

i know that the engine flush smells like kerosine...and has a lot of its cleaning characteristics...but i assume what valvoline was saying about the apex seals had to do with the flush running through the oil injection system and not lubricating the apex seals..........no good.

flush is for 4-stroke motors....not 2-strokes

Rotaries are not two strokes...
But flush is just kerosene to help get out deposits inside of the engine without having to do a tear down to clean it up. Obviously squirting kerosene with the OMP might not be a good idea.
But you could always disable that and run premix in your gas, THEN you can flush away!

All it is - is kerosene. Which has excellent cleaning properties. I have used kerosene (25% kerosene/75% oil mix) as well as the stuff in the can and have had nothing but good experiences with it. This being on piston engines only, I have never and will never try it on my 3 rotaries.
There is a drawback though, engine gunk can sometimes be on your side. Gunk can sometimes "clog" leaks and cracks around oil seals, making it appear (from the outside) to be a sound, non-smoky engine. Once kerosene washes over it, it WILL dissolve these clogs and it will, in a sense, create an already existent leak which will usually come out of your exhaust.
I wouldn't recommend using it on an engine with more than 100,000 miles on it since it was last rebuilt. My .02
