Leak from Front Crank Shaft Seal - Harmonic Pulley replacement
So let's start a few days ago. I had a small oil leak from a bad seal in the crank shaft. It was coined the "front crank shaft seal" by GM. The bolt holding that main harmonic pulley on was on there very tight, and took quite a bit of force to remove. Once that e18 was backed out, it was rather easy to pull on the pulley with my hands to get it off. I did take a quick pic of the way the hole on the pulley was facing, since the Haynes manual mentioned this might be important during reinstall.
