the first rotary engine u rebuilt
for all of out there that is not willing to pay someone else to rebuild your engine and did if yourself, id like to hear about the first rotary rebuild you ever did. im about to do mine in a couple weeks and i have really been on the site everyday getting myself ready so i dont screw anything up. i bought 2 rebuild videos, one from atkins and the other is the one that bruce turrentine made, and i also bought his video of pulling the engine out of the thrid gen. id just like to hear how that first time you did it worked out, did you run into any problems, did you do anything that made it easier, what rebuild kit did you buy and were you happy with the end result when you were all finished. id also like to know if theres anything really important that would be worth doing with the engine out of the car. im doing all the vac lines, housings ported, spark plugs and wires, and a couple other things while im in there. i tried searchin for a thread like this and didnt find one so dont get on me if one already exsists.

My first rebuild was easy. It only requires basic tools, nothing fancy like a piston ring expander or anything like that. Basic tools that you can get at a cheap price. There are a couple larger size sockets you may need, especially for the flywheel nut. I ended up buying an impact gun instead of using a pipe for leverage on that thing. But overall, the rebuild was rather simple.
The only problem I ran into was when I was putting the engine back together. I had it on the engine stand, face down so I could put the rotors and engine plates back together. When I was putting the last rotor on, the smallest piece of the 3pc apex seal fell out and went down the hole where the long tension bolts go. It went all the way down to the front part of the engine. I had to take the whole thing apart to get it out, else I wouldn't be able to get a tension bolt in that hole and properly assemble the engine. Not to mention I would have been missing part of an apex seal. As I was taking the engine back apart, 2 of the coolant seals had come out, and since I had to stretch them to get them in, they wouldn't go back in the second time so I had to replace them.
The moral of the story is to cover all the holes while you are working on the engine so you don't get foreign items in the engine.

my first rebuild was fairly unnerving, but in hindsight it was pretty easy. it was years ago, so i was younger (and much less sage ) it went fine. the engine didn't fire up on the first shot, but after about 2 weeks of trying, it turned out to be the distributor cap.
the engine ran, but after it got to normal operating temperature it would be quite frustrating to start and power would fall off. it was really strong up to about 5500 RPM, then nothing ...
i chalked it up to my using old seals and springs in front half of the motor.
the moral of my story ... at the very least, use NEW springs for a rebuild.

yes id have to say that if your going to take the time in getting it out of the car, and rebuilding it every seal, spring, o-ring, gasket ect... should be replaced. id like to keep this thread going, cause i know that everyone has a story with their first rebuild, and did something that they learned there lesson from that first time. also this would be a good thread for people to read, like me that are getting ready to lose their rotary viginity, lol

ive got a 1980 s1 13b bridgeport and the motor isnt in it nor is it running... i am wondering whether i should rebuild it myself or get it rebuilt... its meant to be easy but i dunno... i dont wanna stuff it up and im just thinking it would be better to pay the extra to get it done and have the extra bit of insurance

My first rebuild was a '74 4 port 13B. I replaced all the springs, had the plates lapped and street ported it myself. That was 3 years ago and it's still running strong. There's no greater satisfaction than turning the key and having it fire up every time.

hey,
any of you out there just rebuild the engine with out any extensive experience with cars (eg. you aren't a mechanic or took some sort of course etc.) im just wondering if it can be done by the average joe (decently) just by watching the videos, reading up and some patience? because not only do you get satisfaction, you do save some money right? although a proffesional rebuild would be ideal.
thx
