Oil leaking from the Exhaust side of the turbo.
 

Here is what I have done.
Bought a 84 Toyota 4x4 with a 2.4ltr Naturally aspirated diesel in it.
I LOVE odd balls like this so I just couldn't pass it up.

I found a guy in Canada that had an exhaust manifold, intake, upgraded turbo and all the lines going to and from the turbo.
Could I pass it up? No!
So now it's a 2.4 ltr Turbo Diesel.
I did some searching and found a cool little unknown (to me) injection shop in SLC that had a BRAND NEW Turbo IP on the shelf. Bought it and tossed that suka on.
So I get it running BTW it runs great or at least I think it does.
The problem, I ran a 3/8 line for the oil feed right from where the oil sender used to be, it has a 1/2 maybe return line on it out of the turbo. so I ran 1/2 down to a oil return already there coming from the vac pump. The return on the vac pump is 3/8 so I had to reduce the return from the turbo down to 3/8 as well. This is where I think my problem is.
I have oil leaking around the waste gate pivot and after running for a while it drips out the tail pipe.

So my question for the group is; should I knock a hole in the pan and weld on a 3/4" nipple then attempt to get a larger return off the turbo so the oil can get out faster?
I think the reservoir in the turbo is under pressure causing the oil to be forced out the exhaust side.
does that make sense?
I had someone tell me I need to do this for the return and restrict the oil feed a bit.
BTW this engine has 60psi of oil pressure when it warm cruising down the freeway.
thanks all

I think you're on the right train of thought, sharing the the line with the vacuum pump isn't allowing enough flow.

Yip, I think I'll head to EVCO house of hose with the turbo drain in mt hand and measurement from the turbo to the pan and get what I need to drain it to the pan.

Thanks
