just swapped an ls into ef hatch and i got it to turn over but it makes a low, slow grinding noise and the engine will ocassionaly jump. and it doesn't turn over very fast. never starts. it just finished re-assembling the motor and put it back in. the starter is working. what could cause this noise?

 

the heat shield under t tranny is hittin? idk

 

sounds like something in the tranny, like the flywheel

 

try taking the heat shield off and inspect the flywheel to see if you notice something adnormal on it

 

the heat shield is underneath the car? cuz the flywheel is exposed on the underside of the trans. i guess i could look under there. thank you
