If you are running a front mount, drain it right back into the timing chain cover..

 

pics going into the timing cover please.

 

This...

 

Yes, the engine is on a stand.

 

Timing chain cover, as u can tell in my particular year model truck the drain on the left wouldnt work due to clearence issues, npt threaded and jb weld!

 

what about this spot???

 

Mine is right below the starter.

 

Because typical T4 frame based turbo's have a 3/4" ID exit from the bottom of the center section. -12 is 3/4" ID. I elected to not step it down. I am a little sensitive to turbo drains considering what I went through installing gravity drain based TT kits on C5's. Granted front mount truck turbo's are typically mounted higher so gravity and their proximity to the pan allow more options. The -12 move was to prevent the question ever arising again if I have a turbo smoking problem or oil winding up in the charge section. I also do not have any 90 degree bends in my drain. It's one less variable to factor into any pontential future troubleshooting.

 

Mine is on the bottom front part of the pan. Has a 90* 1/2
x 3/8 pipe 90* elbow threaded into pan. Have ran this setup for years with no prob. Doesn't fit 2wd's so good tho I hear.

 

I just did a couple 3/8" NPT taps into the front of my oil pan. 5/8" (-AN10) hose fits perfectly over the 3/8" pipe.
