Correct, that's how I pulled the motor the first time for its rebuild. I even left the intake manifold attached.

I actually ordered new pressure place bolts and transmission torx bolts (I figured I should change them, I'm sure my impact gun took a toll on them..)
I just might have a free weekend very soon where I can head down to the Bay in order to drop the trans and investigate.

I had this happen back when I rebuilt a VR6 motor for a Jetta I had. It ended up being that the timing tensioner snapped, causing the chain to skip a few teeth and seize the motor.

I realize i'm comparing apples to oranges, but that was my issue.

Alright. I took the transmission off and the motor spins freely!
Turned out I had the clutch disk mounted backwards.. Ordered a new pressure plate as it took some damage, along with a new slave cylinder as I blew the seals on it when removing the stuck transmission.

It took myself awhile as I have been very busy with school and work! Having three people totally helped.

I had my brother put the transmission in fourth gear and depress the clutch so the slave cylinder would be engaged. Then both me and a friend went underneath and got large pry bars and just went to town. Luckily nothing broke at all, but I think I think i nicked the pressure plate a little bit and I ordered a new one as I did not want to upset the balance on the rotating assembly.

Lesson learned, make sure the sprung hub clutch disk has the larger side of the springs laying INSIDE the flywheel, and not towards the gearbox as the clutch disk states. I reckon this is due to me using the lighter E36 M3 PP and not the E34 M5 PP. Oh well. At least this was not too expensive!

I'll update soon as I get the car back on the ground and finally running again. Its been 16 months off the road now!
