dead FB; engine won't spin

[85'12a-Blake]

well just any other night after work waitin for the manager 2 come out and while i was waitin. something poped in my car and it locked down. i figured out it wasnt the starter. IT mite be a possibilty of the throw out bearing since it was going bad but it still rolls and takes gear. if thats not it then its gotta be internal. Any ideas, its a 12a with 146k on it stock. any suggestions as 2 the problem would be great but will be starting the tear down soon once i get it home. just 2 say ahead of time this is my first rotary so its ok 2 talk 2 me like an idiot b/c i probly wont understand all of the technical lingo

Ouch! With the tranny out of gear, can you rotate the motor by hand?

[85'12a-Blake]

nope motor still dont move....its locked down good....i havent taken a breaker bar 2 try it since it isnt home yet....but it wouldn't move with the starter.....

Did you check the oil? Could of ran low on oil and seized or bearings toast

[85'12a-Blake]

oil level and coolant both are good. but dad said the oil smelt burnt.....idk but he's been building cars for over 30 yrs but not rotarys but still i had the oil changed 1200 miles ago.

what kind of oil do you run, did you see in copper in the oil?

[85'12a-Blake]

idk about the copper in the pan but there wasnt any in the oil on the dipstick. it was Penzoil conventional 10w-40. IT's still sittin @ work not home

time for a new engine, unless your throw out bearing wore down and broke some teeth out of your pressure plate that wedged themselves into the flywheel. its happened to me

[85'12a-Blake]

well thats kinda what my dad said b/c the throw out was gettin pretty loud but didnt have the cash for one and a clutch 2. but we will see soon i just hope if it is the motor that its not too destroyed inside

[12arotary]

if the motor is locked up at least one rotor will be totally demolished 100% guaranteed.
a good way to figure out whether or not its the clutch- the motor will spin backwards so through a socket on the front and try

[85'12a-Blake]

i'll try that 2moro if i got time but i'll be gettin it home monday so i'll just pull it then and find out but thanks appriciate the info

[85'12a-Blake]

well i took a breaker bar 2 it this morning and it broke free but i didnt try a compression stroke. So hopefully that means its the throw out bering and clutch and all that fun stuff.

[12arotary]

you should have been able to tell where the noise came from and if it wasn't the engine it should fire right up

[85'12a-Blake]

well rlly the only noise i heard when it broke free was me fallin on my A** and the wrench falling.....but it feels like it has compression....so you think its a good idea 2 try and start it b4 i tear it down and see?

Pull the trailing plugs one at a time, have somebody turn the motor over while you listen to the air puffs. Listen for an absence of puffs, or for a different rhythm between front/rear.

Good luck...
