I'm here for some help as you can see... Well I have a 3rd gen T/T Rx-7. Last week as I was driving I went from 3rd gear to 4th, before I hit the 4th gear I felt something go, not sure what. When I was at the stop light my car was running like crap. Now!! I think it was the turbo, but not sure due to the amount of black smoke coming out of the tail pipe and with a small amount of oil located in the upper intercooler pipe and in the intake system..Or it could be something else, please help ya!!!

 

Could have popped your motor. If you broke an apex seal it would run like crap. Then pieces of the seal could have damaged your turbos. A compression check is the best way to know if you busted a seal or not.

 

did it sound like bwaaaaaaaaa-pfh! that sucks, second compression check
