How are those exhaust ports closed off for diving the boat?

Holly diesel smoke batman!

Still running fine by sound, correct?

Eichhörnchen, I think they closed by valves inside the boat. The exhaust holes were "always open".

Always a beautiful sound to hear

I didn't realize how loud they really are from the outside.

There are hand valves inside as Rhodes states. I believe the video in the OP with the heavy swirling may be a procedure necessary to the Gato diesels known as 'scavenging' a maintenance procedure to rid the cylinders of all unburned fuel That's a lot of white smoke(supercharged air) in the video not dark indicating fuel. http://maritime.org/doc/fleetsub/diesel/chap6.htm Some opinions please.

Close enough!

The Fairbanks-Morse 38 8-1/8 is a diesel engine of the two-stroke, opposed-piston type.[1] It was developed in the 1930s, and is similar in arrangement to a contemporary series of German Junkers aircraft diesels.[2] The engine was used extensively in US diesel electric submarines of the 1940s and 1950s, as backup power on most US nuclear submarines, as well as in other marine applications, stationary power generation, and briefly, locomotives. A slightly modified version, the 38ND 8-1/8, continues in service on Los Angeles-, Seawolf-, and Ohio-class nuclear submarines of the US Navy. The 38 8-1/8 has been in continuous production since its development in 1938, and is currently manufactured by Fairbanks-Morse Engine of Beloit, Wisconsin.

Obviously the VW defense team has not thrown this dart out in its defense argument of the great pollution scandal....that looked like a lot of pollution on the USS Silversides; ie pollution is acceptable when it's a battlefield deterrent!
