Are you sure that you don't have another open tube?
You could have a collapsed lifter/actuator or your chain tensioner might be weak. The chain should be tight.
I recall that the procedure to check the chain stretch is way more involved than replacing the chain BUT I once asked two major online parts places if they sold a lot of 119 chains. One said "no" and one said "never."

I just checked under the cover, and the tubes plugs are all intact.
A stretched chain is a possibility, but from the sound of it (see youtube video below), it definitely seems to be a single lifter. I've calc'd that at 700 RPM, there should be 5.833 ticks per second: 700 / 60 / 2. The "2" is for two crankshaft rotations per one camshaft rotation. Because the sound on the video is about spot on (it's about 600 to 700 RPM), and because the sound comes from somewhere back toward cylinder #3, I'm pretty sure it's a lifter.
One of these days, though, I would like to check the timing chain stretch. It's a comfort to here from a trusted mechanic I know that he's never had to do that work before on an M119 because he's never bad to....
