Well, I don't know anything about vacuum other than if the hoses aren't connected properly it won't run right. However, I have rebuilt a few engines in the past and just made sure the vacuum lines were connected like they were before I took the engine out, although the last time I did that was over 20 years ago.

Is it because I don't know if valve covers will fit from year to year? Or because I don't know about the crankcase pressure? Yeah, I had no idea that would cause oil to blow out the seals.

Seems to me like $83 for a re-ring kit, or even $400 for one of the more expensive ones, is a heck of a lot cheaper than $6000 for a crate engine...
