i know this type of post pops up all the time but im just trying to get confirmation on what im already thinking. i know that if a rotary sits for any length of time without any sort of activity the apex seals tend to freeze up. well mine has sat for about 6 or 7 months without any engine life. ive only recently gone out and turned the motor over, but its not making me feel any better. you see i can spin the motor over by hand.....bare hands. my upper manifold is off and i can here it making compression, but its still easy to spin over. so is it blown? i remember it was a lot harder to turn over when i first put the motor in, it would snap the wrench out of my hands if i wasnt careful. now it just seems to be way too easy to turn. i can reach up from the front of the car and grab the crank pulley and turn it over using both hands. it just doesnt sit well with me, i dont like it at all. also if it is blown, can i fix it without pulling the motor apart? will some type of oil loosen up the seals enough to bring back the compression? or do i have to pull it entirely apart and basicaly rebuild it? one more thing, can i pull it apart, free up the seals and put it back together without buying a rebuild kit and replacing every single seal in the engine? thanks guys, i appreciate your help.

 

You're supposed to be able to turn the motor by hand. You can in my 7 and in any other healthy 13B. So she's fine.

It wouldn't hurt to put a little oil in each plug hole, and then pull the EGI fuses and crank the motor until you see the oil pressure gauge start to rise (and now your oil lines will be primed.) Then put the fuses back in and fire her up...

 

When I purchased my car, it had sat in my friends backyard for ~9 months. Never started during that time. Not even cranked over.

I towed it home on a trailer, fired it up, and its running strong as ever.

 

If its spinning more freely than you think it should, its probably flooded. Take out the plugs, are they covered in gas?

 

To answer your other question, No. You cannot rebuild it without pulling the motor apart. You will need some new gaskets, but you don't necessarily need all new rotor seals if the ones in the engine measure to be within the tolerance given in any of the manuals for rebuilding the engine.
The best way to see if its blown is to do a compression test.
