Me too. As soon as I found so much play in the flywheel I started imagining the flywheel nut threads being like totally destroyed. I'm happy just the nut itself was damaged or I could have taken the engine back apart.

 

We finally got the 7 back together. It runs really great, lots of power. No more noise from the PP. It starts showing boost under 2k
but it is just starting to break in so I'm keeping under 4k rpm and accelerating slowly and trying to keeping the boost down.
