Leak Down Test On My New 418 Need Help?

I wouldn't say it's complete nonsense. I've seen plenty of engines with a bad hone job or ring swap burn oil and have lots of blow by for a few thousand miles before it gets better.


If it takes a thousand miles to "break in" the rings they are JUNK. They will never be right.

Its F'ing 2018. When will the ring seal lies stop?
