Let me quantify: Re: Uncorked exhaust

["Owen" <renarac@domain.elided>]

It will if there is nothing at all around the ports and you run it for 10K+
miles.

I suppose No donut could do it, but it's probably moot.

I was told that the cold ambient air would encourage crap to develop on the
valve seat. Eventually causing a leak. From that, eventually burning a valve
face.

But this was a crusty old coot. Who knows. He was the first person to show
me the 'ol rope in the cylinder trick when removing valves.
