Harmonic Balancer
I am in the middle of replacing the harmonic balancer on my 2000 C5.
The balancer I bought has a keyway machined in it. I am putting it on a stock engine with no provision for a key and am wondering if the keyway will be a path to leak oil and should it be sealed. Appreciate any advice. Thanks.

My ATI has a keyway as well and doesn't leak a drop. I do have it pinned, but the pin by no means will seal it. I think the pressure of the bolt is enough to contain any oil weepage.
