whats up everyone??? i have a 12a from an 82 gs in my datsun 520 pickup. as i was runningf around, i noticed oil burning on my exhaust. when i checked, it looked like it was from my tranny since it looked to be coming out the rear seal. by the time i was almost home, it shut off. no power and very hard to start back up. when it did start it sounded crappy and was shaking badly. checked the oil and there was NONE!!!! my guess is that it was motor oil leaking but how? how bad did i mess up the motor? any chance that it can be saved or should i just get another one? anyone had this happen to them? im new to the rotary scene so any help will be graetly appreciated. thanks!!!! https://www.nopistons.com/forums/pub...IR#>/blush.gif

pull your spark plugs. if theres a lot oil on them the control rings are bad and might of destroyed the motor.



the only way to tell if the motor is rebuildable, is open it up.

yeah sounds like the oil came out.



pull it apart and see

That sucks man. time to start looking for either a new motor or a good rebiuld kit if the motor hasn't been over heated.

yeah it sucks royally, and i just got it running right. back to the drawing board.....

this happened to me...



alls i needed was new bearings. but i only drove it like that for about half a mile. you might need a new e-shaft if you drove real far like that.

im keeping my fingers crossed. i did drive it for quite a while. so i know its shot. and to top it off, while taking out the motor last night, it slipped and fell on my finger. now i have a big hole on it. imma leave it alone for at least a week. lol

what do you mean it fell on your finger? Did you bust your finger or are you saying that the motor has a hole in it from falling on your finger?
