Looking at it more I think I agree with Tony. I was worried that something came loose or was rattling around, but if that was the case you’ll see more circular patterns from either the timing chain or the retaining bolts hitting the case. These are randomly spaced but more to the center. Just a crap cast job that should never have been used. And now cracked- possibly from overtightening but also weakened from the holes and imperfections from casting.
Got a new one on order.
Anyway, thank you guys for the input. I’m grateful for everyone’s thoughts and responses
Hopefully I’ll have this cobra on the road by next summer. I’ve never even driven one before! So excited. I can only imagine how fun it’ll be to drive.
