Oil sampling 5.3 engine

[SnowDrift]

What would be stopping the tube from going all the way to the oil through the dipstick tube? It is a few inches shy of getting to the oil in the pan.

Trying to pull oil out for a sample rather than drain out

2005 Tahoe if it matters

I've had to try a few times, twisting the tube so the curve goes a different direction.
I've never done anything 2005 Tahoe before. Quite a few others. And boat motors

The best I can tell, I've tried 360 degrees.

Perhaps try cutting a bevel in the tube's end to help it get past bends in the dipstick tube. Might work, might not.

Try the dipstick in different positions. If it can not go down 90° to its current position- then part of the tube or block forces it to only go one way for clearance issues. If that’s the case you might not get any tube down it.

Skinnier tube is only other idea I see.

They're sending me a smaller hose

Burp the oil drain. Just hang onto the drain plug, screw it back in. That's where the swarf is.. (the stuff you need to test).
