Oil return position in motor from turbo?

[4000GT]

Hey guys, where have you put your oil return line? Sump? block? Motor in place or taken out? Threaded connector or weld in? Cheers!

Just welded a steel -10 to the sump,took the sump off.

depends on where the turbo is going to sit.

 

[4000GT]

Front centre, between motor and radiator... pretty much the only place it could go sadly.

In that location, I would weld a fitting on the front edge of the alloy section just below the bolt flange and ofset to one side of the crank pulley.

Just remember, you want the oil drain to be as steep and direct as possible to the pan. So being that the turbo is front and center, the drain location is best to be in the same area.

I find the rear sump configuration is little difficult to return the oil under the crank. Very little space available. So I use the side of the upper oil pan.

is there anything behind that location Lex? Easy to get to motor in the car? I want to avoid removing it if I can.

This where I put mine..

 

[4000GT]

Anything behind there XR8? ok to drill and tap in place?

 

[XR8tt]

Its the smoothest part I could find.. Its tapped with nut and O ring on inside... I could have welded an alloy 15mm pipe....
Obviously this engine is out of car..
Yes there's about 4mm.. I would use O ring and silastic or 5 min araldite

Cool looks like thats my loaction for the oil return.

4000GT,

XR example is from the LS400 or Celsior. The front sump is alot easier. However, rear sump is little harder because the you have very little space for drilling or tapping. Stevechumo did the same location as I did for his single.

 

[4000GT]

Ok, guess I need to see the options, Im more worried about what I might hit trying to drill...

 

[Lextreme II]

I wont worry much about hitting things behind. You will be ok.

On the front sump motors, there's evidently a lot more depth in the alloy pan up front as shown in XR8TT's photo. But Andrew, I think you have a rear sump motor like David, Steve & me, and as David said there's just not much depth in the upper alloy pan at the front of the motor. Here's a pic that shows that area, unfortunately not in great detail.

There's heaps of room on the side of the pan where you can see the -8 AN nipple I put in for my prelube system.

This an old picture but still the same location.

The side wall is very thin. So Markstoy helped me weld two 1/2" bungs to the pan (inside of the pan) for greater security.

Take the oil level sender unit out and flat plate it with a nipple to suit you drain line..

Take the oil level sender unit out and flat plate it with a nipple to suit you drain line..

Only thats where the feed is...

 

[Hennie Marais]

you might be thinking about the oil pressure sender, not the oil level sender, the front sump engine has it on the righthand side of the engine.

You realy need the return above the windage tray...
As close to top of oil pan as you can..Alloy section...
If you can beside main bearing cap where there's no oil sling...
