SBC front balancer seal leaks
What am I doing wrong? I rebuilt the 350 in my 69 three years ago. Had a machine shop go through it and it runs great but it continues to leak at the front seal. I've replaced the front seal three times, balancer twice including going to the larger one, and the timing cover once over the last three years and it's leaking again. Each time it doesn't leak for the first few months. This is not my first motor but the last one I did was some 30 years ago. I'm stumped. Any ideas would be appreciated.
