im so ******* lost.......any one wanna tell me whats up...
god i hope i dont need a new engine *bah*

Do you have any oil pressure reading on your gauge? And where did the oil go???? leak? burnt?
Sorry to say this but it sounds like you roached it. If so, just get a junkyard 12A and swap it out. 13B will cost mucho $$$ more.

LOL head gasket, have you ever looked under the hood? it has 6 apex seals, if it is your car you should get a haynes manual to familiarize yourself with it. 13b would definatly be more $$. what year is your car and how many miles are on the engine?

Now that I got that out of the way.
The bad news:
1. Sounds like your engine popped an apex seal. So find out....you can get a compression tester from a local auto parts store $10-20. Just get a generic on with a release valve. Take a spark plug out and screw in the compression tester in it's spot. Have a buddy crank the engine over while you hold the release valve. Do this with each rotor housing. (2 spark plugs per housing do the lower plugs). This way you can see if you get any compression. Each rotor
has 3 apex seals. So you should get three readings that are about the same. If not you have a busted seal. (Which would require either a new engine or a rebuild.)
2. NEVER EVER FORGET ABOUT THE OIL LEVEL IN A ROTARY ENGINE.
I'm not going to give you a hard time about this seeing how you have already learned your lesson the hard way. (Rotary engines internals are lubricated by the oil that (includes the apex seals). Since the extreme temps the rotary produces the oil helps parts from becoming brittle.
3. 13b's cost more. If you have 12a engine already in there find another. This way you won't have to mess with fabricating anything. Just do a direct swap.
4. Rotary engine have no head gaskets. Just apex seals and side seals. The nice thing about rotary engines are the simplicity of them. Generally speaking it only has 3 moving parts. Two rotors and the eccentric shaft.
The good news:
1. You might get to learn more about the car and engine if you do it yourself.

hey, don't be dissin' on my homey drivefast! anyway, yeh, you killed it. looks like time to call pineapple racing and order a streetport motor, lol. always a good excuse. go to www.howstuffworks.com and search rotary engine. learn everything you can. 2 things you never do. never run out of oil and never overheat. also you never want a rapid change in temps. the motor is a sandwich of metals that all expand at a different rate due to heat. now that if billigerently told you everything plus some after error, i'll wander elsewhere.

Pay no mind to the people who get a chuckle at your expense on here. Error was just tryin to clue you in on how things go on around here. Thank you error for taking the time to do that. Yes howstuffworks has an excellent explantion on how the rotary works.

ya i thought i had a pretty good idea on how our engines worked then went to howstuffworks and it made my brain hurt......... so now any time someone asks me how it works i ask for a pen and a pice of paper and write down the link.... and say look it up bitch i aint go the time
plus it helped that i didnt have much knowledge on piston engines when i strated learning about the mighty rotary ...wasnt clouded by the dark side

Well damn, that's the first time I've gotten that one. LOLNope, I wasn't uptight or upset at all. Trust me, you'll know when I am pist. I guess I should lighten up the welcome message to new members. I try to update it as much as I can to be informative as possible.
The comments about the oil seals being bad I thought was a given, seeing how xX__ziggy__Xx mentioned it burns oil faster then it would take a hooker to replace a condom.
Having the apex seal bust would cause the loud bang. This is why I recommend getting a compression tester to find out what the compression is like. Here is a little right up..
2 = normal compression
1 = low compression
0 = no compression
When testing your compression you should get three readings (one for each rotar facing).
Normal engine: 2-2-2
busted side seal: 0-0-0 (may vary)
1 busted apex seal: 0-0-2
2 busted apex seals: 0-0-0
3 busted apex seals: 0-0-0
Seals that are sealing properly.
worn side seal: 1-1-1 (my vary)
1 worn seal: 1-1-2
2 worn seals: 1-1-1
3 worn seals: 1-1-1

first of all, if you think rotary engines have head gaskets...LOL........then.. i dont know what... but anyways, a blown apex seal would smoke just as much as a side seal. rebuilding the motor would be an option, which would be... i dunno... 2 grand maybe?? unless you need new rotor housings.. thats what costs more.

Did you read the little legend I made?2 = normal compression
1 = low compression
0 = no compression
...it just like me saying...
C = normal compression
B = low compression
A = no compression
Silly people.
