Trust issues

Well think of this......how many small blocks have you ever seen with burnt up timing chains from lack of oil? I've not seen any. I will say I have seen quite a few I KNOW were virgin tear downs that did have that little bolt with the hole drilled through it, so evidently Chrysler did think that was a good idea. It's cheap and it doesn't cause a pressure loss since it just drips out of the intake valley. Nothing wrong with doing that.
I was thinking the opposite way. I didnt like the idea of leaving the bolt out. And i didnt think that drilling the hole would provide enough oil to make a difference, but the pressurized galley would skirt a far amount of oil on the chain and it falls right back into the pan so im not "losing" any oil. But that was just my thinking. Im sure there has been thousands of engines ran all three ways without any issues
