My friend has been learning to use a boroscope.
He sent me a link to a you-tube video of a valve opening and closing. Please take a look: https://www.youtube.com/watch?v=KxebW7Z6Lwg&feature=youtu.be
If you look closely, you can see slight movement in the valve seat as the valve contacts it. I think it is oil that is squeezing out of the seam between the seat and the cylinder head.
I would have thought the seat should be pressed into the head tightly and shouldn't move.
Is this bad? OK? typical?
Should this be addressed immediately? Soon? Let it go until something bad happens?
