My car is a G-body so probably different than what you're doing. The first bung I welded in turned out to be against the subframe. I closed it up and stepped up to a -12 and moved it back a bank. It's fine where it is but in reality after having the car 90% complete I see that I would have been better off going back to the next bank back. That would have allowed me to run the hose on a straighter path instead of making bends or curves in the line.

Dont have a pic, but the flat spot of the pan directly above your factory drain plug is perfect. As high up as you can get it

I was able to tap mine in the front, just below the balancer-it was the GM hot rod pan, so not sure it their deeper there or not
I ran the feed from the piece above the oil filter, used a plate with a 1/8 pipe tap

I bought a metric to a/n adapter and used the oil level sensor hole. You guys see a problem with using this setup? I use -12 return line that definitely flows downward. I hope not or the engine has to come out again.

Awesome thanks guys . I will be tapping above the drain plug and welding a -10an on there. And now I see where the feed comes into play after doing a little searching. Thanks guys

Dumping it back in the timing cover works as well, easier in come cases.

Also -10 on on the small side for most drains. Look at the manufactures minimum suggested drain size. Drain line shouldn't be any smaller than the drain hole on the bottom of the turbo.

That will not work because the oil level sensor is below the oil level so the oil will not drain back into the pan. You'll need to move it up higher on the pan.

Uh oh. Another member has done it on 2 builds. Said it worked with -12 drain which is what i have. I thought there may be a problem. Should have gone with my gut instinct and had the bung welded. ****, i just dropped the motor back in too.

Just run it like you have it. Iv seen other people have it there no issues too. If you have excessive smoke or something then switch things up, but no sense in going back now
