Oil Tube to rockers 49 chevy 216

[mytruck1949]

Guys I found the issue of my noise. it doesn't appear I am getting enough oil to the top of the motor. So after disconnecting the tube in the middle of the lifters I spun the motor in which I found that some oil was coming out but not a lot. Next I pulled it down to find that there was a rub hole where it comes up through. So me being me I figured well time to replace the whole tube right. Well I loosened the lower connector but the tube will not pull out.

So is it a case I have to drop the oil pan?


Also what is the correct term for this tub and probably be a LMC or Elklers purchase I bet.

Next what would be the best route to clean out the feeder holes for each rocker?
Any advise.
