Another comment, the drain pipe/hose needs to be 20% larger than the bottom hole in the CHRA drain.
Most times people use a section of stainless pipe for the drain at least 6 inches long to get away from the
heat of the turbine housing. Then if you want to add some Braided line that is flexible that is ok from that point on.
On a engine that is driven for any period of time the heat from the turbine housing will kill a normal braided shield
drain line.

It's just the pic. Like I said that braided line was just to show you we had room. And we are considering running hard line for about 6". The drain hole is 1/4"npt so the actual hole is a scosh smaller and we're going to use at least 1/2" line to -10 or -12. I'm still shopping around for options. But I do understand about getting that oil out of there. I appreciate any input Tom. Thanks.
