Did you put silicone sealant into the keyway before installing it?

You want to use RTV sealant - it's like a copper/silicone mix that can handle the engine bay temps. Regular silicone paste will melt.

I used this stuff and it works great so far.

Is it the harmonic balancer or the crank pulley? Usually oil leaks with pulleys come from the crank pulley.
