oiling timing chain

View attachment 1715842225 Sorry for the crappy photo. This is what I found when I opened my 68 273.No oil hole or drip tang.
Added both when re-assembled .
How many miles on it?
I'm sure the chain was shot, over 75-150k miles I assume. Its a testament to how much oil already get to the chain imo.
It leaks from the no.1 cam bearing and is carried by the chain @ stop n go as well as the slinger.
