Engine back from machine shop, some concern...
I would suggest an oil analysis after 1k miles or so. That will show if you have any problems relating to excessive wear, blowby, small internal coolant leaks, etc.

Supposed to be a brand new seal that he installed. Looking at everyone elses seals and the install pic from GM, it looks wrong in there and doesnt look fresh either.
