LE5 turbo feeds and drains

Just wondering where everyone is getting their coolant and oil from and where you're draining it. I know there is an Allen bolt in the block that can be removed for oil feed correct? Then are you guys draining into the oil pan or tapping the block? I read oil pan is a no-no due to the pressure exuded by the pump and will wear out the turbo much quicker. How about coolant T fittings? Thanks!

Line it like the turbo cobalt ss's are. I think the return is going in straight to the block at the back.
Or the pan.

Just do the pan no issues here, don't have to worry about metal shavings in the block even if you clean it up

Mine is in the pan too, no problem with it. I got zzps oil pan.
Oil feed from the plug on the back of the block, zzp sells the fitting for this.
Coolant feed i have coming from the drain plug in the water pump, i got the fitting on ebay.
Coolant drain i have the lnf thermostat housing so it has a banjo fitting for return there.

I see the extra port here, but it doesn't look threaded to me. Are you sure the banjo bolt fits? Thanks!
