smoke possibilities?

Can you snake the oil drain line to the front?
I remember you saying it's easier to go toward the rear...

I don't know how your turbo exhaust manifold is designed, but you might be able to drill a hole in either the rotor housings or middle iron?
This has complications due to the fitting / pipe being so close to the hot turbo exhaust manifold though...

If you're going to try a sump, you'll need to pump the oil back into the supply -i.e. the oil pan.
This is not the best way as you're complicating the whole system, but sometimes it's a necessity.
Question is...how do you find a reliable pump that can handle hot oil?

Whatever the case, try to get the oil drain (from the turbo) to drop straight down first.
Try to stay away from bends right at the turbo.
Run the largest hose you can fit.
-10AN is minimum in my book, and I try and shoot for -12AN if possible.
Larger is better, but fittings get expensive!
Actually, stay away from AN fittings is possible...
Use / find flange / pipe like how the stock oil drain is.
This is the least restrictive - look at AN fittings *inside* and a lot of them neck down a lot!
Problem with this set-up is that you gotta use (soft) hose + clamps - heat destroys most types of (soft) hoses.

Good luck!

Thanks Ted. I think my original plan is to get metal pipe with an NPT thread. Screw it in and go straight down for a few inches. Then a 45* to a soft hose adapter. Soft hose to the other adapter and run it onto another hard pipe into the oil pan.

If I still have problems I may just use this:

If I still have problems with that set up I'll plug up the npt fitting on the oil pan, drill and tap into the oil cover. It's just so f'ing crowded up front.

It was raining today so I couldn't grab a picture of my engine bay to give you an idea.

IMNSHO the front cover is too thin to tap 1/2"NPT. Instead see if there is a perfectly flat 1.25" diameter spot and use a bulkhead fitting with some aluminum crush washers. My next option would be to weld a bung on. One more reason to get that TIG

Initial viewings seem to indicate that the 6in 1/2npt pipe to a 3/4 buffer to a 3/4 45* bend to a 3/4 buffer to a hose fitting have solved my smoke issues. It took me over an hour to install all the parts that cost me a whopping $6.00, but I had to remove my upper intake, the turbo itself and I found out that I can't rotate the cartridge/turbine housing like I should be able to. There's still a few things I need to fix, but all in all it's coming together.

If my problem stays fixed and I continue to not see any smoke I will not have to setup a scavenge system.

For a better understanding of this: I have replaced about 10in of soft line that continually rubbed up against the turbo manifold with a hard line to an oil accumulator which is still above the oil level. This in my mind should allow the oil ample space to return and run back to the oil pan. But like I said, I haven't noticed a problem with it *yet* and if I do, I have a back up plan I can initiate. Will check in the morning--just too tired now and apparently have developed an allergic reaction to something.
