MN smoke when coming down from redline....

i was looking up on here and found a guy (forgot his name) used alumaseal on his car when it was smoking and he didnt wanna rebuild it soo.... my car had some of the same symptoms so i got some and it worked.. but only for idling did it work now when i redline and the rpms come back down a puff of white smoke comes out but then its fine... sounds like coolant seals? i will rebuild in the future but as for right now is there a temp fix?

Block sealant is the temporary fix. And how that it's been used, when you rebuild the engine, you'll have the joy of having to remove all that gunk from inside.

Here's the whole process. Not a modern 13B, but the block is basically the same as any rotary:

And if you want to do some porting, here's an example:

Once again, Alumaseal is not a block sealant and has not been shown to build up any crud in the block the way bock sealant does.

If your issue is only happening when coming down from redline, you are probably seeing oil smoke rather than steam. Clouds of smoke when deccelerating is usually due to worn oil control rings (oil gets sucked past due to high vacuum after letting off). Lucas oil stabilizer can reduce these symptoms if they are annoying you. Just replace 1 quart of oil with 1 quart of stabilizer and you should see a significant reduction. I run a quart full time in all of my vehicles.

depends...if its just a regular rebuild itll probably be around 2500-3500 or so... if your rotors or housings are no good then definitely more...
