broken dipstick tube 99 silverado 5.3
I was in the process of pulling the dipstick tube on this engine and it must have been seized because it broke off just below the o-ring. I really dont want to pull the pan to get the remainder of the tube out so I am thinking of just driving it on through and installing the new tube, my thinking is that it should lay in the bottom of the pan and not bother anything. But I am not familiar with the inner workings of this engine I assume the oil pump is screened and probably a windage tray to prevent it from some how flying up into the rotating assy.. I have to admit I dont like the idea of doing this but I dont want to pull the pan and I dont see what it will hurt to stay in there.
So does anyone have any suggestions or comments.

same thing happened to me, it pulled out next oil change on the end of the drain plug magnet.o and i dint bother changing the dipstick either, alot of cars dont have o-rings
on the dipstick, just put a little rtv on it if you want

air flow not to dis ya guy but I dont think there is a chance in hell that air is going to flow through between the dipstick tube and the crankcase. It is my beleif that that o-ring is to prevent an oil leak and as tight as the steel tube fits into the crankcase it is going to seal any outside air from coming in especially with a little gunk build up that is probably there already. But I have been wrong before. So anybody else got any thoughts on this.

Not a problem if you run breathers and removed your PCV, but otherwise it could throw a few gremlins into you tune at low airflow.
