Crank pulley out of balance.
So I revved the car the other day to redline and afterwards heard a weird noise. It was as if something was out of balance. I didn’t think anything of it as it’s been driving fairly normal since and no noise. I was fixing a fog light when I noticed oil collected in the center of the undertray. I removed the tray and found that the seal behind the pulley was wet with oil and oil was sprayed against the front cover and the sway bar and other components. I started the car to see if I could see it spraying from behind there. I noticed the pulley wobbling out of balance right away. Not terribly but enough to cause the pulley to cause a small leak with the seal. When I swapped the motor a couple years ago, I want to say I was able to torque the bolt on the pulley to spec but maybe not? It’s down almost to low on the stick in a couple days of it happening.
Any chance it’s the crank itself wobbling and not the pulley? I want to take it to the dealer at this point but also don’t want to get raped. Anyone have any ideas?

Yeah it’s staying parked until I get it to the dealer. I’m going to call tomorrow. Thanks though

So they're quoting me 2 hours of labor at $150 each and potentially a new pulley. They said that the rubber can wear off the pulley and throw it out of balance. The new pulley is $320 dollars

If I could buy the tool I would do it myself, however when I was doing my swap I searched high and low for it and ended up calling to see if I could buy it from Nissan. Of course you can't, so I was forced to use a tool I created to stop the pulley from moving. Apparently that didn't resolve the issue. If they need to replace the pulley I will buy the AMS lightweight unit instead of an OEM one. That way I'm out $500 and not $700

No because the keyway isn’t in place for the pulley to push against while I’m undoing the center bolt. The flywheel needs to be stopped.
