Leaking main seal

[newguy]

Is there any miracle cure for this? Like an oil additive? Really not looking forward to pulling engine back out after I just put it in

nope...just put a new seal in it. is this a 400 that has been line bored?

It's a 400, I don't know much about it, I inherited it from my dad when he passed away. He only ran it once at a 2 day show with no issues, it has been sitting since thanksgiving of 2011

Some guys claim if u add a crankcase evap system of some kind some oil leaks seem to myst.eriously disappear. Just a thought. Might gain u a couple horse too?
