Slant 6 timing chain lubrication?

well, when I was ready to button up the front of my slant, I did ask myself, where does the oil come from? It's like the chain functions on very little lubrication as it gets something from the crank, and cam bearings. That being said, it's existed for generations that way. I'm just doing cause I'm there~ I wouldn't take the timing cover off a running engine to do this mod~ again, I'm just there and so why not~ ;)

This is an interesting thread about something I didn't even knew had existed as a problem with these engines.
I would like to thank all of you for posting in this thread, it was very informative.
I love it when I get to learn something new.
That's why I love this site!
