Hello!

For some hours ago I tried to start my 300ZX NA 90. The car is in a garage for the winter, and has not been started since late october..

The flywheel in my Z has almost no tooths left.. When the starter is trying to spin the flywheel around, it makes this grinding noise.. but after turning the key couple of times, the engine starts up and works perfectly fine.. Until now..

I turned the key 20-25 times to start my z32, all i hear is grinding between starter and flywheel..After many attempts, the starter got contact with the flywheel, I thought the car started, and suddenly all i hear is a big boom..!

A small amount of white/grey smoke is under the hood when i popped it, and it smells burned clutch..

What on earth is going on ? Was it to much fuel in the cylinders ? Fuel in exhaust system?

I thought the engine was blown, so I took a 27mm pipe and turned the engine 2 times around.. no problem turning it.. So what is wrong ?

I HAD to move the car, thats why i tried so hard to get it started.. Got a Specialty Z flywheel waiting for install.

 

The only thing I could think is the ring gear broke lose and contacted the clutch, I've seen it happen in v8 chevy novas with similar results, depending on the damage, u might need a starter and/or clutch, u wont know for sure until the tranny is pulled lose. I can almost guarantee that there aren't any problems with the motor

 

Throw that flywheel in already and replace your clutch. Project knows what he's talking about, so start with what he suggested.
