Can not be used as a drain. Both sides of that block are pressure.
We use to use -8. Problems when it gets cold.
-10 works great just make sure it drops as straight as possible.
We use -3, -4, and -6 depending on the turbo.
No need to run larger then needed.

couldn't appreciate it more guys!
the turbos have -8 drain fitting on them, so I plan on stepping them up to -10 right away and running a -10 hose and -10 fittings in the pan.

2010 Silverado 4.8L
I took mine to the timing chain cover.
I had a lot of room at the top of the front cover to make a connection.
Being very careful and using a lot of grease while working slowly I managed a hole in the top of the case that I threaded to 1/2" NPT (once again, using a lot of grease).
I flattened out the flow across the hose since the pics but the end of the outlet nipple is about 2" above the top of the inlet nipple. Got 1500 miles on it with no problems whatsoever.

I disagree slightly about oiling turbos...its nearly impossible to over-oil a journal bearing turbo. Basically all of the oil related problems are actually drain problems. Mostly too small of a drain line or not enough height difference if gravity fed.
Stay with the -4 feed. I am actually upgrading my feed to a -6 since the line is 5' long.
